The maximum permissible dose (MPD) of ionizing radiation for occupational exposure is?

The maximum permissible dose (MPD) of ionizing radiation for occupational exposure is established to protect workers from potentially harmful effects of radiation. The correct answer, which indicates a limit of 5.0 rem per year (0.05 Sv), reflects the guidelines set by organizations such as the National Council on Radiation Protection and Measurements (NCRP) and the Occupational Safety and Health Administration (OSHA).

This dose limit takes into account the fact that individuals working in radiation-related fields may encounter higher levels of exposure than the general public, which is subject to stricter limits. Regular monitoring and adherence to this MPD allow for the safe management of radiation exposure among workers while still enabling vital medical and industrial applications of radiation.

Lower options like 0.05 rem, 1.0 rem, and 0.5 rem indicate significantly lower exposure limits that are more suited for the general population rather than for occupational settings, where workers can be trained and provided with protective measures that mitigate potential risks associated with higher radiation levels. Thus, the designated maximum permissible dose for occupational exposure is set higher to accommodate the realities of certain jobs, while still prioritizing safety.
