What is the maximum allowable annual whole-body dose of ionizing radiation for radiation workers?

• A. 1 rem
• B. 2 rem
• C. 5 rem
• D. 10 rem

Answer: (C)

The maximum allowable annual whole-body dose of ionizing radiation for radiation workers is established by regulatory guidelines to ensure the safety and health of individuals who are regularly exposed to radiation. The widely accepted limit for radiation workers is 5 rem (which is equivalent to 50 millisieverts). This standard is set based on various factors, including the biological effects of radiation exposure and the need to minimize the risk of radiation-induced health effects over a lifetime. The choice of 5 rem as the maximum annual dose reflects a balance between the necessity for radiation in medical and industrial applications and the importance of protecting workers from excessive exposure. This limit is designed to reduce the long-term risks of developing radiation-related illnesses, such as cancer. Other options, such as 1 rem, 2 rem, and 10 rem, do not conform to the established guidelines for occupational exposure. A lower limit like 1 rem would be overly restrictive for workers who require higher exposure in their jobs, while a limit of 10 rem would exceed the recommendations and increase the risk of adverse health effects. Therefore, 5 rem is recognized as the appropriate safe maximum for annual exposure in a controlled working environment.
