Pre-Medical Dosimetry program

Join an in-demand healthcare career

Medical dosimetrists plan the treatment for patients receiving radiation therapy. Medical dosimetry requires critical thinking and problem solving, as well as a good understanding of cross sectional anatomy. 

Pre-Medical Dosimetry is NOT a major at UW-La Crosse. It is a statement of your intention to apply to Medical Dosimetry programs. You will still need to select a major to complete your undergraduate degree. Radiation Therapy is common, but not a requirement. An undergraduate degree in a biological and physical science is encouraged.

What is a medical dosimetrist?

Medical Dosimetrists work as part of the cancer treatment team. Working in collaboration with the medical physicist and radiation oncologist, the medical dosimetrist uses their knowledge of physics, anatomy, and radiobiology to plan optimal radiation treatment techniques and dosing.

Make your intention to pursue a career in Medical Dosimetry official by adding it as an "intended pre-professional track".

Declaring a Pre-Medical Dosimetry track will help you determine common program requirements, including UWL's. However, program requirements vary at other institutions. When selecting coursework, it is important to consult the websites of the programs to which you plan to apply.

Many professional schools do not accept prerequisite courses that have been taken online or at non-U.S. institutions; AP, IB, AICE, and community college credit policies vary by school/program.

Grow through experience

Shadow or observe a medical dosimetrist

Shadow or observe a medical dosimetrist. This is a great way to experience the profession and learn more about what it takes to become a medical dosimetrist. UWL’s graduate program requires a minimum of 40 hours. Be sure to check the requirement for the program you plan to apply for.

Gain healthcare experiences

Prior direct patient healthcare experience is required for many programs. These experiences can be volunteer or paid positions, but they need to involve direct patient contact. Some examples may include: Recent graduates of a radiation therapy or imaging sciences program; prior work experience in radiation therapy or imaging sciences; volunteer or paid experience as an EMT, lab tech/phlebotomist, or nursing assistant.

Polish technical skills

UWL's graduate program in Medical Dosimetry provides a list of technical standards required of Medical Dosimetrists.
