What is the dose limit for children under 18 years old in terms of occupational exposure?

The correct choice indicates that the dose limit for occupational exposure for children under 18 years old is set at 10% of the adult limit. This approach reflects the understanding that children are more sensitive to radiation exposure due to their developing bodies and longer life expectancy, which increases the potential for long-term health effects from radiation.

In many regulatory frameworks, the adult occupational dose limit is typically around 5,000 mrem (or 5 rem) per year. Applying the 10% standard means that for individuals under 18, the limit would be 500 mrem per year, thereby emphasizing the precautionary principle in protecting young people from excessive exposure.

This aspect of radiation protection regulations is designed to ensure that younger individuals, who may not be as informed about the risks or have the means to protect themselves, receive additional safeguards. Such protective measures contribute to a broader commitment to health and safety in environments where radiation exposure is a potential risk.
