Thermoluminescence dosimetry system
DTU-01M (Ukraine)
Purpose and field of use:
personal dosimetric control of employees working with sources of ionizing radiation as well as environment control in normal and emergency situations
Characteristics and metrological performance:
detected radiation – x-ray and gamma;
range of individual and ambient equivalent dose of photon radiation – 10^5...50 Sv;
range of detected photon energies with dosimeters DTU-1 measuring
Hp(10) – 0.015...3 MeV;
range of detected photon energies with dosimeters DTU-2 measuring
Hp(10) and H*(10) – 0.08...3 MeV;
energy dependence of sensitivity within the range of detected photon energies for dosimenters DTU-1 and DTU-2 – not more than 30%;
anisotropic sensitivity of DTU-1 dosimeters at photon energy 65 keV within angle range ±60° – not more than 15%;
limit of acceptable basic relative error of the DTU-01M system – 20%.
