What type of radiation is primarily measured by Self Reading Dosimeters (SRD)?

Self Reading Dosimeters (SRDs) are specifically designed to measure gamma radiation, which is a type of ionizing radiation that is highly penetrating and can travel significant distances in air and penetrate most materials. SRDs are handy in a variety of settings where exposure to gamma radiation could occur, such as in medical facilities, nuclear power plants, and research laboratories.

Gamma radiation is not only prevalent in various occupational environments but also poses the highest risk for radiation exposure due to its penetrating power, making accurate measurement essential for safety protocols. SRDs provide immediate feedback to the user about their exposure levels, which is crucial for effective radiation safety management.

In contrast, while dosimeters can sometimes measure other types of radiation, such as alpha or beta radiation, SRDs are specifically optimized for gamma detection and do not provide the same level of accuracy or functionality for measuring neutron radiation or other forms of radiation.
