Radiation Therapist Job Description Templates

6 free templates by setting. Download as DOCX or copy-paste.

The radiation therapist job description carries more weight than most clinical postings, because the person you hire delivers radiation treatment to cancer patients and works with high-energy equipment and radioactive sources under strict safety rules. Whether you are a small freestanding radiation oncology center making a key clinical hire or a hospital department filling a staff role, the posting has to communicate the exact credentials, the setting, and a real safety mandate. The generic templates from the big job boards give you one thin block of duties that reads the same for a two-machine clinic and a large cancer center, and they gloss over the credentialing and FLSA details that matter most.

At FirstHR, we build for the practices behind those hires, including small and independent radiation oncology clinics that handle hiring without a dedicated HR department. The six templates below cover the real versions of the role: general staff therapist, small or independent clinic, hospital or health system, entry-level, senior or chief, and the synonym title radiation therapy technologist. Each carries the ARRT credential, the setting, and the non-exempt classification the role needs. Fill in the brackets and post. For the fundamentals behind any posting, the guide to writing a job description covers the basics.

Six free, ready-to-use radiation therapist job description templates by setting: General / Staff, Small / Independent Clinic, Hospital / Health System, Entry-Level, Senior / Chief, and Radiation Therapy Technologist. Download as DOCX, fill in the brackets, and post. Use the precise title, state the ARRT credential and state license, write radiation safety in, and classify the role carefully since many therapists are non-exempt.

What Does a Radiation Therapist Do?

A radiation therapist delivers prescribed radiation treatments to cancer patients, operating the linear accelerator, administering the dose, monitoring patients, and following strict radiation safety protocols as part of the oncology team. The O*NET profile for radiation therapists frames the core: positioning patients, calibrating and operating the machine, delivering the prescribed dose, and maintaining records while following radiation protection principles.

The defining feature for an employer is the credentialing and the title precision. The role is also called a radiation therapy technologist or radiation oncology technologist, all the same job, and it is distinct from a radiologic technologist who does diagnostic imaging and a medical dosimetrist who calculates dose. The setting also changes the job: a small clinic therapist wears many hats, while a hospital therapist works across multiple machines in a larger team. For adjacent clinical roles in a small practice, the medical assistant templates and the nurse job description templates cover those seats with the same structure.

Radiation Therapist Duties and Responsibilities

Radiation therapist duties center on treatment delivery, patient care, safety and compliance, and the records and teamwork that hold the oncology team together. The setting shifts the weights, a small clinic therapist carries a broad version while a hospital therapist is more specialized, but the four categories hold. These are the duties grouped the way the templates use them.

Treatment delivery
Deliver prescribed treatments accurately and safely
Operate and monitor the linear accelerator
Administer the prescribed dose per the plan
Patient care
Position patients and verify treatment setup
Monitor patients during treatment
Explain the process and reassure patients
Safety and compliance
Follow radiation safety and ALARA principles
Maintain dosimetry badge monitoring
Support HIPAA and accreditation requirements
Records and teamwork
Maintain accurate treatment records and doses
Work with the oncologist, physicist, and dosimetrist
Support QA and equipment checks

A strong posting selects the responsibilities from each area that match your setting rather than listing every possible task. Safety belongs near the center, not the bottom, because a radiation oncology role lives in radiation protection and dose accuracy. For a structured way to scope any role before posting, the guide to defining job responsibilities walks through the process.

Which Template Should You Use?

Radiation Therapist vs Rad Tech vs Dosimetrist

Before you post, settle which role you actually need, because radiation therapist, radiologic technologist, and medical dosimetrist are routinely confused and carry different credentials, work, and pay. Picking the right title keeps the posting accurate and the candidates relevant.

RoleWhat they doCredential
Radiation Therapist (RTT)Deliver radiation treatment to cancer patientsARRT in Radiation Therapy
Radiation Therapy TechnologistSame role, alternate titleARRT in Radiation Therapy
Radiologic Technologist (rad tech)Diagnostic imaging: X-ray, CT, MRIARRT in Radiography
Medical DosimetristCalculate radiation dose and treatment planDosimetry certification (CMD)

Use radiation therapist or radiation therapy technologist when you need someone to deliver treatment. If the work is diagnostic imaging, you need a rad tech, and if it is dose calculation, you need a dosimetrist. Naming the role precisely in the posting prevents a flood of mismatched applicants and sets clear expectations.

Radiation Therapist Qualifications and Credentials to Include

Radiation therapist qualifications combine formal education with firm clinical credentials, which makes specificity essential: the posting either names the real degree, certification, and license requirements, or it draws candidates who cannot legally do the work. The difference shows in how the requirements are written.

Vague requirementSpecific requirement
Degree in healthcareAssociate's or bachelor's degree in radiation therapy
Certification requiredARRT certification in Radiation Therapy (ARRT-RT)
License requiredState license in radiologic technology where required
CPR certifiedCurrent BLS / CPR certification
Technical skillsExperience with linear accelerator and [IMRT / IGRT / SBRT]

Keep every requirement job-related and neutral, because the EEOC prohibits job advertisements that express a preference based on protected characteristics. State the credentials as firm requirements and ask for proof in the application, and the ARRT radiation therapy credential page explains the certification candidates must hold.

How to Write a Radiation Therapist Job Description

A strong radiation therapist posting takes about twenty minutes once you settle the setting, the credentials, and the classification. Here is the process the templates are built around. If you are building out a small clinical team, the small business hiring guide covers the steps around the posting itself.

1
Choose the setting
Pick the version that matches the role: general staff, small clinic, hospital, entry-level, senior, or technologist. The setting shapes the scope and the team.
2
Use the precise title
Use radiation therapist or radiation therapy technologist with ARRT-RT, and do not confuse it with a rad tech or a dosimetrist, which are different roles.
3
State the credentials
List the ARRT certification in radiation therapy, a state license where required, and BLS or CPR certification as firm requirements.
4
Write safety and compliance in
Include radiation safety, ALARA, dosimetry monitoring, and HIPAA, because a radiation oncology hire carries real regulatory weight.
5
Set pay and classify carefully
Publish a pay range, and classify the role non-exempt unless a documented duties and salary review clearly supports exemption, since many therapists are owed overtime.

Radiation Therapist Salary

Radiation therapist pay is high for an allied health role, and it varies by setting, region, experience, and shift. The federal data gives a useful anchor for setting a competitive range.

Radiation Therapist Pay (BLS, May 2024)
Radiation therapists earned a median annual wage of $101,990 as of May 2024, about $49 per hour, with the lowest 10 percent under $77,860 and the highest 10 percent above $141,550 (U.S. Bureau of Labor Statistics). Employment is projected to grow 2 percent from 2024 to 2034, with about 900 openings each year, mostly from retirements and turnover.

Many roles are paid hourly, which matters for overtime since many therapists are non-exempt. Pay runs higher in high-demand metropolitan areas and varies across hospitals, physician offices, and outpatient centers. For an employer setting the rate, anchor on local market pay for your setting, publish a range, and remember that because the role is often non-exempt, overtime adds to the true cost of the position. The limited number of openings each year means competition for credentialed therapists is real, so a competitive rate and a clear, credential-specific posting help you compete.

What Hiring a Radiation Therapist Takes

A large hospital hires radiation therapists through a recruiting team, with HR handling credentialing, classification, and onboarding. A small or independent radiation oncology center makes the same clinical hire with far less infrastructure, often with the practice manager or owner-physician writing the posting and onboarding the therapist personally. Here is how to write the posting, and plan the hire, for that reality.

Use the right title, because radiation therapist, radiologic technologist, and dosimetrist are three different jobs that get confused
Radiation therapist has clear synonyms and clear non-synonyms, and mixing them up in a posting attracts the wrong candidates. A radiation therapist, also called a radiation therapy technologist or radiation oncology technologist, delivers prescribed radiation treatment to cancer patients and holds the ARRT certification in radiation therapy. That is one role under several names. It is not the same as a radiologic technologist, the rad tech who performs diagnostic X-ray, CT, or MRI imaging, and it is not the same as a medical dosimetrist, who calculates the radiation dose and typically holds a separate certification and a higher salary. These are distinct occupations with distinct credentials, and a posting that blurs them wastes everyone's time. Name the role precisely, radiation therapist or radiation therapy technologist with ARRT-RT, and the right applicants will recognize it.
Be careful with FLSA: many radiation therapists are non-exempt and owed overtime despite a six-figure salary
This is the costliest mistake a small clinic makes, because the high salary makes exempt status look obvious when it often is not. Exemption under the learned professional rule generally requires advanced knowledge acquired through a prolonged course of specialized intellectual instruction, and Department of Labor guidance on technologists indicates that an associate's degree plus a certification exam does not automatically meet that bar. That means many radiation therapists, especially those paid hourly with an associate's degree, should be classified as non-exempt and are entitled to overtime for hours over 40, regardless of how high the annual pay is. Misclassifying them as exempt to avoid overtime is a serious wage-and-hour risk. The safe approach is to treat the role as non-exempt unless a careful, documented analysis of the specific duties and salary clearly supports exemption, and to confirm it rather than assume.
Write the compliance and credentialing requirements into the posting, because a radiation oncology hire carries real regulatory weight
A radiation therapist works with radioactive sources and high-energy equipment, so the hire comes with credentialing and compliance that a generic posting ignores. State the credentials plainly: ARRT certification in radiation therapy, a state license where required (most states license radiologic technology), and current BLS or CPR certification. Then plan for the onboarding that this role demands: verifying the ARRT credential and state license, radiation safety orientation under ALARA principles, dosimetry badge issuance and monitoring, HIPAA training, and readiness for state radiation control and accreditation requirements. A small clinic without a dedicated HR function carries all of this manually, and missing a license verification or a safety step is a real liability. Putting the credentials in the posting screens candidates, and planning the compliance onboarding protects the clinic from day one.

From Hiring to Onboarding

The job description is step one, and once a radiation therapist accepts, the same document becomes the basis for the offer and a thorough onboarding, because a clinical radiation role carries heavier credentialing and safety requirements than most hires. Start with the paperwork spine: the signed offer letter, the I-9 and W-4, and state new hire reporting, collected per the new hire paperwork guide. Then the clinical onboarding this role demands: verifying the ARRT credential and state license, a radiation safety orientation under ALARA principles, dosimetry badge issuance and monitoring, HIPAA training, BLS confirmation, and orientation to your specific linear accelerator and treatment systems.

Because this hire carries real regulatory weight, a missed license verification or safety step is a genuine liability for a small clinic. The documents around the hire follow the usual sequence: the offer letter template for the terms, and a structured onboarding template to turn the first weeks into a repeatable, compliant plan. FirstHR connects the HR side of it: e-signature for the offer letter and policy acknowledgments, document storage for ARRT certificates, state licenses, dosimetry records, and BLS cards, training modules to deliver and record radiation safety and HIPAA training, and a structured onboarding checklist, in one place built for clinics that hire without an HR department.

Key Takeaways
Pick the template by setting, general staff, small clinic, hospital, entry-level, senior, or technologist, because the setting changes the scope and the team.
Use the precise title: radiation therapist and radiation therapy technologist are the same role, but a rad tech and a dosimetrist are different jobs with different credentials.
State the credentials firmly: an associate's or bachelor's degree in radiation therapy, ARRT certification, a state license where required, and BLS or CPR.
Classify carefully: many radiation therapists are non-exempt and owed overtime despite a six-figure salary, so confirm by duties and salary rather than assuming exempt.
Use BLS data as a baseline: radiation therapists earned a median of $101,990 in May 2024, with pay varying by setting and region.
Onboard for compliance: verify the ARRT credential and license, run radiation safety and HIPAA training, and issue dosimetry monitoring before the first treatment.

Frequently Asked Questions

What does a radiation therapist do?

A radiation therapist delivers prescribed radiation treatments to cancer patients as part of the oncology team. Federal data describes the role as administering doses of radiation to patients who have cancer or other serious diseases. The work covers four areas: treatment delivery, including operating the linear accelerator and administering the prescribed dose accurately and safely; patient care, including positioning patients, verifying treatment setup, and monitoring patients during treatment; safety and compliance, including following radiation safety and ALARA principles and maintaining dosimetry badge monitoring; and records and teamwork, including maintaining accurate treatment records and working with the radiation oncologist, physicist, and dosimetrist. The role is also known as a radiation therapy technologist or radiation oncology technologist, which are alternate titles for the same job. It requires an associate's or bachelor's degree in radiation therapy, ARRT certification, and a state license in most states.

What should a radiation therapist job description include?

A strong radiation therapist job description includes a job summary, key responsibilities across treatment delivery, patient care, safety, and teamwork, required credentials, and compensation. Be precise about the title, since radiation therapist, radiologic technologist, and medical dosimetrist are three different jobs that get confused. State the credentials clearly: an associate's or bachelor's degree in radiation therapy, ARRT certification in radiation therapy, a state license where required, and current BLS or CPR certification. Specify the setting and equipment, since a small clinic and a large hospital department run differently. Include a pay range and the FLSA classification, and note that many radiation therapists are non-exempt and owed overtime despite a high salary. The templates in this article give you the full structure to customize by setting, including a version written for small independent radiation oncology clinics.

What are the main duties and responsibilities of a radiation therapist?

Radiation therapist duties fall into four areas. Treatment delivery: operating and monitoring the linear accelerator and imaging, and administering the prescribed radiation dose accurately and safely per the treatment plan. Patient care: positioning patients, verifying treatment setup against the plan, monitoring patients during treatment, and reassuring them through a difficult process. Safety and compliance: following radiation safety and ALARA principles, maintaining dosimetry badge monitoring, and supporting HIPAA and accreditation requirements. Records and teamwork: maintaining accurate treatment records, doses, and settings, supporting quality assurance and equipment checks, and collaborating with the radiation oncologist, physicist, and dosimetrist. In a small clinic, one therapist carries a broad version of all four, while in a large hospital department the role is more specialized across multiple machines and a larger team. A strong posting selects the responsibilities that match your setting rather than listing every possible task.

What is the difference between a radiation therapist, a radiologic technologist, and a dosimetrist?

These are three distinct roles that are easy to confuse. A radiation therapist, also called a radiation therapy technologist, delivers prescribed radiation treatment to cancer patients using a linear accelerator and holds the ARRT certification in radiation therapy. A radiologic technologist, often called a rad tech, performs diagnostic imaging such as X-ray, CT, or MRI, not radiation treatment, and is a separate occupation with a lower median wage. A medical dosimetrist calculates the precise radiation dose and treatment plan, typically holds a bachelor's degree plus specialized dosimetry certification, and earns a higher median wage than a therapist. For hiring, the distinction matters because the credentials and the work are different: use radiation therapist or radiation therapy technologist when you need someone to deliver treatment, rad tech when you need diagnostic imaging, and dosimetrist when you need dose calculation. Naming the role precisely in the posting prevents a flood of mismatched applicants.

Is a radiation therapist exempt or non-exempt from overtime?

Often non-exempt, despite a high salary, which makes this a common and costly classification mistake. Exemption under the learned professional rule generally requires advanced knowledge acquired through a prolonged course of specialized intellectual instruction, and Department of Labor guidance on technologists indicates that an associate's degree plus a certification exam does not automatically meet that standard. Because many radiation therapists hold an associate's degree and are paid hourly, they should often be classified as non-exempt and are entitled to overtime for hours worked over 40, regardless of how high the annual pay is. The six-figure salary does not by itself make the role exempt. Treating a non-exempt therapist as exempt to avoid paying overtime is a serious wage-and-hour risk, especially for a small clinic without HR support. The safe approach is to treat the role as non-exempt unless a careful, documented review of the specific duties and salary clearly supports exemption, and to confirm rather than assume.

How much does a radiation therapist make?

Radiation therapist pay is high for an allied health role. Federal data reports a median annual wage of $101,990 as of May 2024, with the lowest 10 percent earning less than $77,860 and the highest 10 percent earning more than $141,550, which works out to a median of about $49 per hour. Pay varies by setting, region, experience, and shift, with hospitals, physician offices, and outpatient centers paying differently, and metropolitan areas with high demand often paying more. Many roles are paid hourly, which matters for overtime since many therapists are non-exempt. Employment of radiation therapists is projected to grow about 2 percent from 2024 to 2034, slower than average, with roughly 900 openings each year, mostly to replace those who retire or move on. For an employer setting the rate, anchor on local market pay for your setting, publish a range, and remember that because the role is often non-exempt, overtime adds to the true cost of the position.

What qualifications and credentials does a radiation therapist need?

Most radiation therapist roles require an associate's or bachelor's degree in radiation therapy, certification by the American Registry of Radiologic Technologists in radiation therapy, and a state license in the many states that license radiologic technology. Current BLS or CPR certification is commonly required as well. Federal data notes that radiation therapists typically need an associate's or bachelor's degree and that most states require licensure or certification, which often includes passing a national certification exam. Beyond credentials, the role needs strong technical skill with the linear accelerator and treatment systems, careful attention to detail for accurate dose delivery, physical stamina, and the interpersonal skill to support cancer patients through treatment. For an employer, the practical move is to state the ARRT certification and state license as firm requirements, ask for proof of credentials in the application, and verify them before the first day, since this is a regulated clinical role.

What happens after I hire a radiation therapist?

Once your radiation therapist accepts, the job description becomes the basis for the offer and onboarding, and onboarding a clinical radiation role is heavier than most because of the credentialing and safety requirements. Start with the paperwork spine: the signed offer letter, the I-9 and W-4, and state new hire reporting. Then the clinical onboarding that this role demands: verifying the ARRT credential and state license, a radiation safety orientation under ALARA principles, dosimetry badge issuance and monitoring setup, HIPAA training, and BLS or CPR confirmation, plus orientation to your specific linear accelerator and treatment systems. Because this hire carries real regulatory weight, a missed license verification or safety step is a genuine liability for a small clinic. FirstHR handles the HR onboarding side for small radiation oncology centers: e-signature for the offer letter and policy acknowledgments, document storage for ARRT certificates, state licenses, dosimetry records, and BLS cards, training modules to deliver and record radiation safety and HIPAA training, and a structured onboarding checklist, all in one place built for clinics that hire without a dedicated HR department.
