Radiation Safety Practice Exam

Why is care recommended when handling thorium check sources?

1. They are highly flammable

2. They are prone to rust

3. They can cause radiation exposure

4. They are difficult to replace

The correct answer is: They can cause radiation exposure

Handling thorium check sources with care is essential primarily because they can cause radiation exposure. Thorium is a naturally occurring radioactive element, and when handled improperly, it can expose individuals to radiation, which is harmful to health. This risk necessitates strict adherence to safety protocols to ensure that radiation levels remain within safe limits and to protect both the handler and others in the vicinity. Radiation exposure from thorium sources can result in various health effects depending on the level and duration of exposure. Therefore, understanding the principles of radiation safety, such as limiting exposure time, increasing distance from the source, and using appropriate shielding methods, is crucial when working with these materials. This awareness and preparation help to mitigate the potential risks associated with radiation exposure from thorium sources.
