ASNT Industrial Radiography Radiation Safety Practice Test

What is the maximum dose a declared pregnant radiographer or assistant may receive during the entire pregnancy?

1. 100 mR (1000 μSv)

2. 250 mR (2500 μSv)

3. 500 mR (5000 μSv)

4. 1000 mR (10000 μSv)

The correct answer is: 500 mR (5000 μSv)

The correct answer is significant because it reflects the established safety standards for protecting the fetus during pregnancy while working in environments where radiation exposure is a concern. The maximum dose limit for a declared pregnant radiographer or assistant is set at 500 mR (5000 μSv) for the duration of the entire pregnancy. This limit is established by regulatory agencies to minimize the potential risks associated with radiation exposure to both the mother and the developing fetus. This standard is rooted in the understanding that the fetus is particularly sensitive to the effects of ionizing radiation, especially during the early stages of development. The 500 mR limit is designed to provide a safeguard that balances the need for radiographic work with the importance of health precautions taken for pregnant workers. By adhering to this guideline, the safety of both the pregnant employee and the unborn child is prioritized, thereby promoting a responsible approach to radiation safety in industrial settings.
