How to Become a Medical Dosimetrist

Growth Trends for Related Jobs

Radiation therapy is used in the treatment of malignant cancers. A medical dosimetrist is part of the radiation team, ensuring that the right amount of lethal radiation hits the cancer cells without damaging healthy organs and tissues. The average annual salary for medical dosimetry jobs range from $105,037 to $125,040.

Job Description

After a physician prescribes radiation for a tumor, the medical dosimetrist creates a plan to deliver the prescribed dose. Using a computer with 3-D imaging software, the dosimetrist contours normal organs from a CT scan, a PET/CT scan or an MRI to determine the exact location of the tumor. The dosage and the arrangement of radiation beams are then calculated, to be reviewed by the radiation oncologist, who is the medical doctor specializing in cancer treatment by radiation. After the doctor's approval, the dosimetrist finalizes the treatment plan and will make sure that it is executed as designated.

Education Requirements

Becoming a dosimetrist requires completion of a 12- month medical dosimetry certification program from an accredited institution. Admissions to schools are competitive; most require a minimum of a bachelor's degree in physical science. Applicants are usually required to complete an observation of medical dosimetry to get an understanding of what's involved in the profession.

There is no CMD degree, but instead a Certified Medical Dosimetrist (CMD) designation earned by certification exam through the Medical Dosimetrist Certification Board (MDCB). There was previous an option for certification based on clinical experience, but as of 2017, only graduates from 12-month medical dosimetry certification programs who also have a bachelor's degree are eligible to take the exam.

Along with formal education requirements, dosimetrists must have excellent communication skills. They must listen to the radiation oncologist to understand treatment goals. They must accurately document the treatment plan and communicate exactly what is needed to the radiation therapist who will actually administer the dosage. Dosimetrists must have be good at problem-solving and have excellent computer, math and technical skills.

Work Environment

Dosimetrists work in hospitals, medical centers and cancer treatment centers. They are part of a medical team that includes physicians, medical physicists, oncology nurses and radiation therapists.

Salary and Job Outlook

The U.S. Bureau of Labor Statistics (BLS) tracks data and makes predictions for all civilian occupations. The BLS includes medical dosimetrists under the category of radiation therapists, and projects a job growth rate of 13 percent through 2026, a rate faster than average, compared to all other jobs. Advances in radiation therapy, as well as the aging of the general population, will likely contribute to the increase in medical dosimetry jobs.

The average salary for a dosimetrist is $114,992, as of October 2018. Factors such as geographic location, employer, education, experience and additional skills account for salary variations.
