Accurate measurement of radiation dose is crucial for ensuring safety in fields such as nuclear energy, medical radiation, and industrial radiation. The FN-2000B thermoluminescence radiation dose detection system launched by Feinuofei Technology (Shanghai) Co., Ltd. accurately measures radiation dose using the phenomenon of thermoluminescence, providing strong technical support for radiation safety.

　　Principle of Thermoluminescence Technology

Thermoluminescence (TL) is a physical phenomenon in which certain substances are excited to high-energy states by electrons after absorbing radiation energy. When these electrons return to the ground state under thermal excitation, they will release photons. By measuring the number of these photons, the radiation dose absorbed by the crystal can be accurately determined.
