What is the density of NaI (Tl) scintillator?

The density of NaI (Tl) scintillator, which is an important material used in various types of radiation detection, is approximately 3.67 g/cm³. This density contributes to its effectiveness as a scintillator, as the density affects the interaction of gamma photons within the material, resulting in the production of detectable light when ionizing radiation passes through it.

The choice of NaI (Tl) as a scintillation material is largely due to its favorable properties, including high atomic number (Z), which allows it to efficiently convert gamma photons to visible light. The relatively low density compared to other materials can be advantageous for certain applications, such as portability and ease of handling.

Understanding the density of scintillator materials is crucial in applications like PET imaging, as it influences the design and efficiency of the detection systems crafted to maximize the capture of emitted gamma radiation.
