Which type of OSLD detects beta and photons?

  1. Type LA

  2. Type AA

  3. Type SRD

  4. Type CD

The correct answer is: Type AA

The correct answer is associated with the OSLD (Optically Stimulated Luminescent Detector) that is specifically designed to effectively measure both beta particles and photons. This type of OSLD incorporates materials that are sensitive to both radiations, allowing for accurate detection and measurement in various environmental conditions or clinical settings. For example, Type AA OSLDs are constructed with specific materials or filters that help in capturing the energy from beta radiation and photons, making them versatile for radiation safety applications. This capability is particularly significant in medical and environmental monitoring, where clinicians and safety professionals need comprehensive data on different types of radiation exposure. In contrast, other types of OSLDs might be optimized for specific energy ranges or types of radiation, which limits their applicability. Understanding the characteristics and intended uses of various OSLD types helps ensure that the correct detector is selected for a given measurement scenario.
