Medical Health Physics provides radiation monitoring devices to measure an individual's radiation exposure from X-ray or radioactive sources. The standard monitoring device is a clip-on dosimeter badge or ring badge bearing the individual’s name and monitoring period.
A radiation dosimeter badge does not protect the worker from radiation but detects and measures exposure levels. The badge detects high-energy beta, gamma, or x-ray radiation but cannot detect low-energy beta radiation from some isotopes, including tritium (H-3).
To minimize your exposure to radiation from radioactive materials or radiation- producing devices, always practice the “As Low As Reasonably Achievable” or ALARA principle, which includes minimizing time near a source, maximizing distance, and using shielding between you and the source.
