Radiation Safety Practice Exam

What is the maximum radiation exposure allowed for minors or declared pregnant females per year?

1. 100 mREM

2. 500 mREM

3. 1000 mREM

4. 5000 mREM

The correct answer is: 500 mREM

The maximum radiation exposure allowed for minors or declared pregnant females is established to protect their health, as they are particularly sensitive to radiation's potential harmful effects. For minors and declared pregnant females, the regulatory limit is set at 500 mREM (or 5 mSv) per year. This limit serves to minimize the risks associated with radiation exposure during crucial developmental periods. Minors, due to their ongoing growth and development, have a higher susceptibility to radiation-induced effects, including cancer. Similarly, for declared pregnant females, the limit is designed to protect both the mother and the developing fetus, as the fetal tissues are more radiosensitive. The limit is significantly lower than what is permitted for adults, reflecting the necessity for additional precautions in these vulnerable groups. Understanding these limits is essential in maintaining safety and health standards in environments where radiation exposure is a factor.
