There is experimental evidence for the production of non-Cerenkov radioluminescence in a variety of materials, including tissue. We constructed a Geant4 Monte Carlo simulation of the radiation from P32 and Tc99m interacting in chicken breast and used experimental imaging data to model a scintillation-like emission. The same radioluminescence spectrum is visible from both isotopes and cannot otherwise be explained through fluorescence or filter miscalibration. We conclude that chicken breast has a near-infrared scintillation-like response with a light yield three orders of magnitude smaller than BGO.
有实验证据表明，包括组织在内的多种材料中会产生非切伦科夫辐射发光。我们构建了一个Geant4蒙特卡罗模拟，用于模拟P32和Tc99m在鸡胸肉中相互作用产生的辐射，并使用实验成像数据对类似闪烁的发射进行建模。两种同位素都能观察到相同的辐射发光光谱，无法通过荧光或滤光片校准错误来解释。我们得出结论，鸡胸肉具有近红外类似闪烁的响应，其光产额比BGO小三个数量级。
