What is the primary function of personal dosimeters?

The primary function of personal dosimeters is to track individual radiation exposure. These devices are crucial for monitoring the amount of ionizing radiation a person may be exposed to while working in environments where radiation is present, such as hospital settings, nuclear power plants, or research laboratories.

Personal dosimeters provide a quantitative measure of radiation exposure over time, allowing individuals and safety officers to ensure that exposure levels remain within established safe limits. This monitoring is essential for protecting workers' health and complying with regulatory standards regarding radiation safety.

The other options focus on different safety concerns that are not related to radiation exposure. For example, protecting against electrical hazards pertains to electrical safety, measuring body temperature is related to health monitoring, and detecting chemical spills is focused on chemical safety. None of these pertain to the specific function of personal dosimeters in measuring radiation exposure.
