What is one primary function of handheld radiation detectors?

Handheld radiation detectors are primarily designed to conduct surveys for locating radiation sources. These devices can detect and measure the presence of radiation in an environment, making them essential tools for identifying potential radiation hazards. This capability is crucial in various settings, such as nuclear facilities, medical institutions, environmental monitoring, and emergency response scenarios.

The detectors work by sensing ionizing radiation, which includes alpha particles, beta particles, gamma rays, and X-rays. When used in surveys, these devices can provide immediate readings that help users pinpoint the location and intensity of radiation, allowing for timely and informed decision-making to ensure safety and compliance with regulations.

Other functions listed, such as measuring temperature variations, providing medical diagnoses, and analyzing chemical compositions, do not pertain to the primary role of handheld radiation detectors. These devices specifically focus on radiation detection and measurement, which is integral for radiation safety and monitoring efforts.
