Overview
The GR-TLD series lithium fluoride thermoluminescent detectors are passive, solid-state integrating-type detectors. Their key features include small size (high spatial resolution), effective atomic number close to that of air and human tissue, immunity to electromagnetic interference, a wide measurement range, low lower detection limit, good reproducibility, and the capability to measure high-dose-rate pulsed radiation fields. They are applicable to personal monitoring of ionizing radiation, environmental monitoring, and measurement in specific radiation fields (including differential measurement in mixed neutron-gamma fields). They can also be applied in fields such as radiological medicine, radiobiology, reactor engineering, and archaeology.
