What is the occupational dose equivalent limit for radiation exposure?

100 Rem
50 Rem
25 Rem
200 Rem

The correct answer is: 50 Rem

The occupational dose equivalent limit for radiation exposure is established to protect workers in environments where they may be exposed to ionizing radiation. The recognized standard for the annual dose limit for radiation workers is 50 Rem (or 500 millisieverts). This standard is set by authoritative organizations such as the National Council on Radiation Protection & Measurements (NCRP) and the American National Standards Institute (ANSI), reflecting a balance between the benefits and risks associated with radiation exposure in the workplace. The limit of 50 Rem is consistent with the philosophy of radiation safety, which includes reducing exposures to as low as reasonably achievable (ALARA) while allowing for some practical exposure levels that benefit occupational roles in various fields such as medicine, industry, and research. Meeting this regulatory standard helps safeguard the health and safety of radiation workers by minimizing the risk of radiation-related health issues over the course of their careers.
