![]() Regulatory requirements for the assessment and recording of external exposures are set forth by different federal agencies such as the Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE). They permit radiation protection professionals to not only ensure people are not being exposed excessively, but to demonstrate that regulatory dose limits have not been exceeded.Īre there regulations that apply to external exposure monitoring? These devices not only detect but measure the amount of exposure. In fact, the use of personnel dosimeters is one of the most important aspects of a monitoring program. Is the use of personnel dosimeters a common practice? Another typical approach is to use devices called “personnel dosimeters” One way of assessing external exposures is to measure the exposure rate in the location of interest then simply multiplying that value by the amount of time spent in that location. How do you evaluate the magnitude of an external exposure? This section focuses only on evaluating exposures from external sources. In a previous chapter of this basic introduction to concepts of radiation and radioactivity, we discussed the ways of evaluating internal radiation exposures. Simply stated, an individual can be exposed to radiation from either an internal (inside the body) or external (outside the body) source of radiation. How can a person be exposed to radiation?
