When a patient is diagnosed with cancer, they often work with a team of healthcare professionals who provide a wide variety of services to help them get well. The leader of this team is typically an oncologist and other well-known professionals are involved such as nurses, social workers, genetic counselors, and pathologists. If a patient is to receive radiation therapy, a dosimetrist is added to this team. While they are lesser known, they ensure patients get adequate care. 

Dosimetrists’ primary job is to design, generate, and measure patient radiation doses. They will calculate overall dose distributions and provide oversight to the entire radiation therapy process. They have an in-depth understanding of math, physics, anatomy, physiology, and radiobiology to tailor treatments to a patient’s particular kind of cancer or tumor.

For each patient, dosimetrists start with simulations to locate the cancer or tumor with scans and then create immobilizing devices to ensure patients will not move during treatment. Once the simulation is complete and the oncologist has determined the specific treatment modality, dosimetrists will administer radiation therapy. 

The two primary therapy methods are external beam radiation, where radiation is delivered outside the body, and brachytherapy, where radiation is placed inside a patient’s body. 

To work in this field, dosimetrists must complete at least a bachelor’s degree in math, physics, or dosimetry. Many professionals in this field earn a master’s or certificate in dosimetry to have the necessary skills and knowledge. Certification is optional for dosimetrists, although many employers may require it. The primary certification body for dosimetrists is the Medical Dosimetry Certification Board (MDCB)

This is a detail-oriented, highly technical career. Keep reading to learn what it takes to become a dosimetrist, including top programs, typical wages, job duties, and certification steps.  

Dosimetrist Specializations & Degree Types

Dosimetrists must have at least a bachelor’s degree to practice in this field. There are only four bachelor’s programs in medical dosimetry in the United States, so many professionals pursuing this career earn a degree in a related field such as math or physics. 

Upon completing a general bachelor’s degree, students must pursue either a master’s or certificate in medical dosimetry. These programs are offered both at universities and hospitals or clinics.

Admissions Requirements for Dosimetrist Programs

Admission requirements for dosimetry programs vary based on the type of degree and the institution. Bachelor’s degree programs require applicants to have completed high school and take a national standardized exam such as the ACT or SAT. Bachelor’s degree dosimetry programs are often just the junior and senior years of a student’s degree. These programs require students to complete general education requirements and prerequisite coursework before applying. 

Master’s or certificate programs require applicants to have earned bachelor’s degrees. Preferably, this bachelor’s degree is in math or physics. Many master’s or certificate programs require applicants to hold an American Registry of Radiologic Technologists (ARRT) certificate to be eligible for admission. 

Lastly, some programs may require a minimum number of years of work experience in radiation technology. 

Dosimetrist Program Accreditation

The Joint Review Committee on Education in Radiologic Technology (JRCERT) accredits dosimetry education programs. Currently, there are only 14 certificate, bachelor’s, and master’s programs accredited by the JRCERT. Students should ensure their dosimetry program is JRCERT accredited, as this is a requirement to be eligible for Medical Dosimetry Certification Board (MDCB) certification. 

JRCERT accreditation assures students, employers, and the MDCB that a program has met strict quality standards in faculty, curriculum, and facilities. JRCERT standards were updated in 2021 to ensure students receive the highest education level. 

In addition, all JRCERT-accredited programs must submit year programmatic effectiveness rates and an assessment to ensure they continue to meet standards.
