Overview
The GR-200 series thermoluminescence neutron dosimeter belongs to passive solid-state integral detectors. Its characteristics are small size (high spatial resolution), effective atomic number close to air and human tissue, no interference from electromagnetic radiation, wide measurement range, low measurable lower limit, good reproducibility, and pulse radiation field that can measure high dose rates. They can be applied to personal monitoring of ionizing radiation, environmental monitoring, and specific radiation field measurements (including differential measurements of n and gamma mixed fields). It can also be applied to disciplines such as radiology, radiobiology, reactor engineering, archaeology, etc.
