What is the primary use of a pocket dosimeter?

1. To measure noise exposure

2. To measure employee exposure to radiation

3. To measure chemical exposure

4. To track temperature changes

The correct answer is: To measure employee exposure to radiation

A pocket dosimeter is primarily used to measure employee exposure to radiation. This device is designed to give an immediate indication of the amount of ionizing radiation an individual has absorbed over a certain period. Pocket dosimeters are often used in environments where exposure to radioactive materials is a concern, such as medical facilities, nuclear plants, or research laboratories. The dosimeter functions by utilizing a specialized mechanism, typically involving a gas-filled chamber or a crystal that reacts to radiation, allowing for the detection and measurement of accumulated doses. The readings provided by a pocket dosimeter help ensure that workers are not exceeding safe exposure limits, thereby promoting health and safety in potentially hazardous environments. The other options listed revolve around different hazards. Measuring noise exposure typically requires a sound level meter, while chemical exposure assessments often involve sampling devices or badges designed to capture specific chemicals. Tracking temperature changes is unrelated to radiation exposure and would typically utilize thermometers or temperature data loggers. Therefore, option B accurately reflects the primary purpose of a pocket dosimeter in occupational safety.
