What medical dosimetrists do
Typical tasks
- Design the arrangement of radiation fields to reduce exposure to critical patient structures, such as organs, using computers, manuals, and guides.
- Plan the use of beam modifying devices, such as compensators, shields, and wedge filters, to ensure safe and effective delivery of radiation treatment.
- Identify and outline bodily structures, using imaging procedures, such as x-ray, magnetic resonance imaging, computed tomography, or positron emission tomography.
- Calculate the delivery of radiation treatment, such as the amount or extent of radiation per session, based on the prescribed course of radiation therapy.
- Calculate, or verify calculations of, prescribed radiation doses.
- Develop radiation treatment plans in consultation with members of the radiation oncology team.
- Supervise or perform simulations for tumor localizations, using imaging methods such as magnetic resonance imaging, computed tomography, or positron emission tomography scans.
- Create and transfer reference images and localization markers for treatment delivery, using image-guided radiation therapy.
- Record patient information, such as radiation doses administered, in patient records.
- Advise oncology team members on use of beam modifying or immobilization devices in radiation treatment plans.
- Fabricate beam modifying devices, such as compensators, shields, and wedge filters.
- Perform quality assurance system checks, such as calibrations, on treatment planning computers.

Projected pay for Medical Dosimetrists (3, 5 and 10 years)est.
Today $147,470 → in 3 years $159,600 → in 5 years $168,200 → in 10 years $191,700 (10-year range $164,900–$222,600). The model assumes pay growth of +2.7% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (BLS projected employment growth), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →
