Abstract (English):
Results of research of absorbed dose rate dependence on distance and on positioning accuracy of standard dosimetric beta-radiation sources at the new AT200 calibration facility (by ATOMTEX SPE) are presented. The non-uniform profile of beta-radiation fields created by sources with strontium-90 + yttrium-90, krypton-85 and promethium-147 radionuclides under conditions as specified in ISO/DIS 6980-2:2021(E) international standard was investigated.
