Frequently Asked Questions
Which occupations need dosimetry badges?
Dosimetry badges are needed in jobs where workers might be exposed to ionizing radiation. The goal is to track how much radiation a person actually absorbs over time (and keep it within legal safety limits).
Here are the main job categories that typically require them:
Healthcare & Medicine
- Radiologists & radiologic technologists
- X-ray, CT, MRI (MRI doesn’t use ionizing radiation, but staff in mixed imaging departments may still wear badges)
- Interventional cardiologists
- Nuclear medicine technologists
- Radiation therapists
- Dentists and dental assistants (especially those taking X-rays)
- Veterinary staff performing radiography
- Veterinarians who take or assist with X-rays
- Veterinary technicians / nurses
- Animal handlers or assistants who restrain animals during radiography
- Specialty vets (orthopedics, equine, emergency/trauma) who use imaging frequently
Nuclear & Energy
- Nuclear power plant workers
- Nuclear reactor operators
- Fuel handling and waste management staff
- Radiation safety officers
Science, Research & Industry
- Laboratory researchers using radioactive isotopes
- Medical and industrial physicists
- Industrial radiographers (e.g., weld inspection using gamma/X-rays)
- Semiconductor and materials testing technicians
Aviation & Space
- Airline pilots and flight attendants (cosmic radiation exposure)
- Astronauts
- High-altitude research crews
Manufacturing & Construction
- Non-destructive testing (NDT) technicians
- Workers using radiation-based gauges (thickness, density, moisture gauges)
- Mining workers (especially uranium or radon-heavy environments)
Environmental & Government Roles
- Environmental radiation monitoring staff
- Emergency responders trained for radiological incidents
- Regulatory inspectors (nuclear, medical, industrial facilities)
- Military personnel working with nuclear systems or radar (for ionizing exposure)
*Important nuance
- Not everyone in these fields wears a badge all the time.
- Badges are usually required when exposure could exceed a certain fraction of annual dose limits.
- Rules vary by country (OSHA, NRC, IAEA, etc.).
