What is the dose equivalent limit for a radiography student who is under 18 years of age?

The dose equivalent limit for radiography students who are under 18 years of age is indeed set at 1.0 mSv per year. This limit is established to protect the developing bodies of minors, who are more sensitive to the effects of ionizing radiation compared to adults.

Regulatory guidelines emphasize that individuals under the age of 18 should have stricter exposure limits since their cells are still actively dividing and they have a longer life expectancy during which radiation-related health issues could manifest. The limit of 1.0 mSv reflects a cautious approach to radiation protection for this vulnerable population to minimize the risk of potential long-term health consequences, such as cancer.

In contrast, the other options present recommended dose limits that apply to adult workers or higher exposures than what is deemed safe for those under 18, which further highlights the importance of the specific limit assigned to this age group.
