RADIAC instruments that operate on the scintillation principle are divided into which two categories?

• A. Digital and analog
• B. Liquid and solid crystals
• C. Portable and stationary
• D. High and low sensitivity

Answer: (B)

The correct answer identifies that RADIAC instruments based on the scintillation principle can be categorized into systems that use liquid or solid crystals. Scintillation detectors work by detecting and measuring ionizing radiation through the emission of light (or scintillations) when radiation interacts with certain materials. Liquid scintillation detectors use a liquid solution with dissolved scintillator materials to capture radiation. This liquid medium allows for a wide range of radioactive isotopes to be measured effectively. On the other hand, solid scintillation detectors use solid crystals (such as sodium iodide doped with thallium) that produce scintillation light in response to radiation. Both types are instrumental in various applications for measuring different forms of radiation, such as gamma rays and beta particles. This distinction is crucial for users to select the appropriate detection method based on the specific application or type of radiation they need to measure, leveraging the unique properties and efficiencies of each category. Understanding these categories is vital for effective radiation detection and safety practices in different environments. The other categories, such as digital/analog, portable/stationary, or high/low sensitivity, refer to different operational or functional characteristics of instruments but do not specifically relate to the materials (liquid vs. solid) that produce the scint
