Frequency and process for exchange: Dosimeters are issued for either a one month or three month wear period.

Who is required to wear dosimeters?

Who needs a dosimeter? Radiation workers who operate x-ray machines, flouroscopy units, certain unsealed and sealed radioisotopes or are exposed to other sources of gamma or high energy beta radiation are generally required to wear one or more dosimeters.

How much radiation is considered safe?

Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is “as low as reasonably achievable; however, not to exceed 5,000 millirems” above the 300+ millirems of natural sources of radiation and any medical radiation.

How can we detect radiation in a person?

Detecting radiation is achieved through the use of a variety of instruments. The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter.
