What type of radiation do nuclear gauges typically use?

Nuclear gauges typically use gamma radiation because it has the ability to penetrate materials more effectively than alpha or beta radiation. Gamma rays are high-energy electromagnetic radiation, which allows them to interact with the materials being measured without significantly altering their properties. This characteristic is essential for the accurate measurements that nuclear gauges provide in various industries, such as construction and mining.

Gamma radiation is also less ionizing than alpha particles, making it safer to use under controlled conditions when proper safety protocols are followed. Its penetrating power enables it to pass through dense materials, allowing for the evaluation of thickness and density in real time, which is crucial for ensuring quality control during manufacturing processes. This is why gamma radiation is the preferred choice for nuclear gauges, as it delivers reliable data necessary for making informed decisions in various applications.
