UDK 539.16.08 Общие основы и теория измерений и конструкции измерительных приборов. Методы измерений
The article considers an algorithm for creating a mathematical operator that allows one to convert the readings of a beta-radiation detector operating in the spectrometric mode into an absorbed dose in a tissue-equivalent material at a depth of 70 μm. The algorithm is based on the detector response matrix obtained using Monte Carlo simulation. The correctness of the operation of the mathematical operator was verified by direct measurements of beta radiation with known characteristics. For this purpose, an experimental beta-radiation detection unit was developed at ATOMTEX SPE.
