Which device is primarily used for personal dose measurement in radiation safety?

• A. Geiger-Muller counter
• B. Dose rate meter
• C. Dosimeter
• D. Neutron detector

Answer: (C)

The correct choice for personal dose measurement in radiation safety is the dosimeter. A dosimeter is specifically designed to measure an individual's exposure to ionizing radiation over a period of time. These devices provide a quantitative measure of radiation dose received by personnel working in environments where radiation is present, helping to ensure that exposure remains within safe limits set by regulatory bodies. Dosimeters come in various forms, such as film badges, thermoluminescent dosimeters (TLDs), or electronic personal dosimeters, and they are typically worn on the body to provide continuous monitoring. The data collected from dosimeters can be used to assess cumulative exposure and verify compliance with safety protocols. In contrast, while devices like Geiger-Muller counters and dose rate meters are useful for detecting radiation and measuring the radiation environment in general, they do not provide an accurate personal exposure dose over time. Neutron detectors are specialized tools used to monitor neutron radiation specifically, but they are not commonly used for personal dose measurement, making them less applicable in the context of individual exposure assessments.
