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.).
