The medical dosimetrist is a member of the radiation oncology team that plays a role in the management of cancer. Medical Dosimetry allows professionals to utilize their knowledge of mathematics, medical physics, science, and critical thinking in his/her everyday work. Medical Dosimetrists specialize in the planning of optimal radiation treatment techniques and dose calculations in collaboration with the medical physicist and radiation oncologist.

According to the American Association of Medical Dosimetrists (AAMD), the professional organization, the medical dosimetry profession is described as:

After the Radiation Oncologist has consulted with the patient on their plan of treatment, he/she will write a prescription of radiation dose to a defined tumor volume. The medical dosimetrist will then design a treatment plan by means of computer and/or manual computation to determine a treatment field technique that will deliver that prescribed radiation dose. When designing that plan, also taken into consideration are the dose-limiting structures. These structures could include the eye when treating the brain, the heart when treating the lung, or the spinal cord when it is included in the area of treatment.

The medical dosimetrist maintains a delicate balance between delivering the prescription the physician has written while ensuring the patient will not lose important healthy organ function. In many institutions, the medical dosimetrist also has the ability to execute planning for intracavitary and interstitial brachytherapy procedures.

Following the planning process, the patient will have a simulation for tumor localization to ensure reproducibility of treatment set up and plan delivery. Here, it may be necessary to produce moulds, casts, and other immobilization devices for accurate treatment delivery. A medical dosimetrist may supervise, perform, or assist in this process. The medical dosimetrist will then work with the radiation therapists in the implementation of the patient treatment plans including: the correct application of immobilization devices, beam modification devices, approved field arrangements, and other treatment variables.

The advancements in computer technology place us at the forefront of many new processes. Using imaging modalities such as CT scans, alone or in combination with MRI or PET scans, we plan with 3-D computers that enable us to give higher doses of radiation to a tumor while lowering the doses to the sensitive structures around it. In some environments we play a part in cutting edge clinical research for the development and implementation of new techniques in cancer treatment. It is an exciting and amazing profession to work in. We are members of a team that contributes toward cancer survivorship on a daily basis.

In summation, 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.

Skills Needed


  • possess an understanding of the technical aspects of radiation oncology and medical physics to derive computerized treatment plans.  They communicate these aspects to the Radiation Oncologist for plan approval and to the Radiation Therapist for plan implementation.
  • are able to perform routine duties independent of supervision, consulting with the Radiation Oncologist and Medical Physicist as required.
  • operate and perform quality assurance on the treatment planning system , under the direction of the Medical Physicist.
  • have a working knowledge of radiation safety in addition to the current rules and regulations of the Nuclear Regulatory Commission.
  • are able to interpret and execute treatment plans as defined in relevant treatment protocols.
  • possess mathematical skills including algebra, trigonometry, and introductory calculus and are able to visualize objects in three-dimensional concepts to facilitate the treatment planning process.
  • are experienced and comfortable with computer operations and functions.
  • are at ease with having close patient contact while working in a health career field.

Career Outlook

The future job market for Medical Dosimetry is strong.  The advances in treatment planning increase the demand for qualified medical dosimetrists.  Wages are comparable with other healthcare professions.  Given the diversity and ever changing technology of the job, lifelong career satisfaction is achievable.


After successful completion of the medical dosimetry program and six months of work experience, students are eligible to apply to take the medical dosimetry certification exam.  The exam is held in various locations throughout the United States every year in June.  The Medical Dosimetry Certification Board (MDCB) is the credentialing body for the certification exam.

Gainful Employment Disclosures

Federal regulations require that institutions disclose certain information on educational programs that do not lead to a degree, such our Track 2.  Information and the required disclosures related to the gainful employment of Track 2 students is provided at Gainful Employment Disclosures.

The University is accredited at the institutional level by the Higher Learning Commission of the North Central Association. Additionally, the UWL- Medical Dosimetry program is accredited by a discipline-specific, professional accreditation organization - the Joint Review Committee on Education in Radiologic Technology.

The program completed the most recent accreditation site visit in July of 2011 and received an 8 year accreditation, with no citations. This is the maximum accreditation awarded by the JRCERT. The interim report is due in 2015 and a re-accreditation is due in 2019.

What does an accredited program mean to a prospective student?             

  • The profession is assured, through programmatic accreditation, that educational programs in the field are providing consistent minimum education in the profession as the profession itself has defined it.
  • Through the process of programmatic accreditation, educators are assured that their educational programs are keeping pace with the profession and with standards developed through national consensus.
  • Accreditation of educational programs assures patients that students who perform procedures have appropriate supervision during the educational process. It also assures them that graduates will have met the minimum level of competency as defined nationally by the profession.
  • Accreditation of an educational program provides students, as graduates, assurance that the educational program will provide them with the requisite knowledge, skills, and values to competently perform the range of professional responsibilities expected by potential employers nationwide. It also assures they will be eligible for licensure in each of the 50 states. By requiring programs to teach the entire curriculum developed by the professional society, the American Society of Radiologic Technology, it also assures students they will have the foundation knowledge to continue to develop as professionals in the various fields of the radiation sciences.
