GR series lithium fluoride thermoluminescence detectors are passive solid integral detectors. It is characterized by small size (high spatial resolution), effective atomic number close to air and human tissue, free from electromagnetic radiation interference, wide measurement range, low measurable lower limit, good reproducibility, and high dose rate pulse measurement characteristics of the radiation field. They can be applied to personal monitoring of ionizing radiation, environmental monitoring, and measurement of specific radiation fields (including the differential measurement of n and γ mixed fields). It can also be used in radiology, radiation biology, reactor engineering, archaeology and other disciplines.
| Item | Specification |
| Detection object | X, γ-ray; Material: LiF: Mg, Cu, P or LiF: Mg, Ti optional |
| Detection object | Neutron rays; Material: 6LiF: Mg, Cu, P or 6LiF: Mg, Ti optional |
| Shape | Disc (also square, powder, square rod optional) |
| Specifications | φ4.5×0.80mm (other specifications can be customized) |
| Energy response | (photons from 30KeV to 3MeV): <20% |
