Texas Industrial Radiography Gamma Practice Test

Pocket dosimeters used in industrial radiography should ideally have a range of:

1. 0 to 100 mR

2. 0.1 to 1 R

3. 0 to 200 mR

4. 100 to 1000 mR

The correct answer is: 0 to 200 mR

Pocket dosimeters are essential tools in industrial radiography for monitoring exposure to gamma radiation. They provide immediate readings of radiation dose received by personnel, which is critical for safety and compliance with exposure limits. The ideal range for pocket dosimeters is designed to encompass low to moderate levels of radiation exposure, which are typical in most industrial radiography applications. A range of 0 to 200 mR allows users to accurately measure doses at levels encountered during regular operations, ensuring that personnel can track their exposure in real-time. This range is particularly suitable as it accommodates typical exposure scenarios while being sensitive enough to detect low doses. The lower end of this range ensures that even minor exposures are measurable, promoting safety and adherence to regulations. Meanwhile, the upper limit of 200 mR helps protect against instances where higher levels of exposure might occur, thus fostering a safe working environment for radiography professionals. Other ranges do not provide the same balance of sensitivity and applicability for typical radiographic exposures. For instance, ranges that start at higher minimums may miss lower exposures, and those that extend too high may lead to a lack of needed precision in monitoring common dose levels.
