RCIS Practice Test 2025 – All-in-One Exam Prep

The correct answer is 5 REM, which aligns with the guidelines established by the National Council on Radiation Protection and Measurements (NCRP). This organization recommends that the maximum annual dose of radiation for occupational exposure should be limited to 5 REM (or 0.05 Sieverts) for radiation workers. This level is considered safe for individuals whose jobs involve regular exposure to radiation.

The rationale behind this limit is to minimize the risk of radiation-related health issues, including the potential for cancer development and other radiation-induced illnesses. By setting a maximum annual dose, regulatory bodies aim to protect workers in industries such as healthcare, nuclear energy, and research, where exposure to ionizing radiation is possible.

Other choices reflect levels that exceed those commonly accepted safety limits for occupational exposure. Maintaining a standard of 5 REM helps ensure that safety protocols and measures are effectively protecting individuals in these environments.
