Product introduction

DA-2000B Thermoluminescent dose reader can measure the thermoluminescence detector after X, γ, β, neutron and other rays irradiation, give the reading value and dose value, with automatic calibration, deduction Functions such as background, heating parameter setting and printing. The thermoluminescent dose reader can be connected to a computer, and data management and printing can be performed through the application software of the thermoluminescent dose reader. It is suitable for environmental background measurement to radiotherapy dose, radiation flaw detection exposure dose control, nuclear accident dose measurement and monitoring, etc.
