About Medical Dosimetry, M.S.

What is Medical Dosimetry?

According to the American Association of Medical Dosimetrists (AAMD) at www.medicaldosimetry.org, the Medical Dosimetrist is a member of the radiation oncology team who has knowledge of the overall characteristics and clinical relevance of radiation oncology treatment machines and equipment, is cognizant of procedures commonly used in brachytherapy and has the education and expertise necessary to generate radiation dose distributions and dose calculations in collaboration with the medical physicist and radiation oncologist.

The Medical Dosimetrist performs calculations for the accurate delivery of the Radiation Oncologist's prescribed dose, documents pertinent information in the patient record, and verifies the mathematical accuracy of all calculations using a system established by the Medical Physicist. We perform, or assist in, the application of specific methods of radiation measurement including ion chamber, thermoluminescent dosimeters (TLD), or film measurement as directed by the Medical Physicist. Another area that we may contribute to is giving technical and physics support to the Medical Physicist; this support could be in radiation protection, qualitative machine calibrations, and quality assurance of the radiation oncology equipment. Also, we often take on the role of educator in facilities that have radiation oncology residents, radiation therapy students or medical dosimetry students.

Mission, Goals and Outcomes


The program’s mission is to provide graduates with the knowledge, clinical skills, and professional behaviors for a career in Medical Dosimetry.   


Upon completion of the program students will be able to:

  1. demonstrate clinical competence.
  2. communicate effectively.
  3. develop critical thinking and problem solving skills.
  4. demonstrate professional behavior in clinic and the profession.


Students will apply didactic knowledge to treatment plans.

Students will generate clinically acceptable IMRT/VMAT treatment plans.

Students will communicate effectively with healthcare staff.

Students will communicate effectively through written work.

Students will evaluate, critique, and recommend changes to the radiation therapy plan as necessary.

Students will participate in the development of optimal treatment strategies.

Students will demonstrate professional behavior in the clinic.

Students will engage in the medical dosimetry profession.

** GVSU Dosimetry Program started in August 2015 with the first cohort graduating August 2016. This data will be updated annually after graduation dates. No five year averages available yet**

· Credentialing examination, job placement, and program completion data must be reported annually to the JRCERT. Graduate and employer satisfaction data must be collected as part of the program’s assessment process.

· Credentialing examination pass rate is defined as the number of graduates who pass, on first attempt, the Medical Dosimetrist Certification Board (MDCB) certification examination or an unrestricted state licensing examination compared with the number of graduates who take the examination within twelve months of graduation.

· Job placement rate is defined as the number of graduates employed in medical dosimetry compared to the number of graduates actively seeking employment in medical dosimetry. The JRCERT has defined not actively seeking employment as: 1) graduate fails to communicate with program officials regarding employment status after multiple attempts, 2) graduate is unwilling to seek employment that requires relocation, 3) graduate is unwilling to accept employment due to salary or hours, 4) graduate is on active military duty, and/or 5) graduate is continuing education.

· Program completion rate is defined as the number of students who complete the program within 150% of the stated program length. The program must establish a benchmark for its program completion rate. The program specifies the entry point (e.g., required orientation date, final drop/add date, final date to drop with 100% tuition refund, official class roster date, etc.) used in calculating program’s completion rate.

· Graduate and employer satisfaction may be measured through a variety of methods. The methods and timeframes for collection of the graduate and employer satisfaction data are the prerogative of the program.
