What is the annual occupational whole-body dose-equivalent limit for a student under the age of 18?

1 mSV
5 mSV
10 mSV
20 mSV

The correct answer is: 1 mSV

The correct annual occupational whole-body dose-equivalent limit for a student under the age of 18 is set at 1 mSv (millisievert). This limit is established due to the increased sensitivity of younger individuals to ionizing radiation. Regulatory bodies, such as the National Council on Radiation Protection and Measurements (NCRP) and the American National Standards Institute (ANSI), recommend stricter exposure limits for minors as a protective measure. This dose limit acknowledges that younger individuals are still developing, and therefore, exposure to radiation presents a higher risk of potential adverse effects, including cancer and genetic damage over their lifetime. By enforcing a limit of 1 mSv, the guidelines aim to minimize risk and ensure the safety of students who may be training in environments where radiation exposure could occur. In contrast, the higher limits associated with other choices are designed for adult occupational exposure, and thus, are not applicable to individuals under 18 years of age.
