Аннотация доклада:
The International Code of Practice (CoP) IAEA TRS-483 provides a formalism for dosimetry in small fields of MV photon beams. It includes specific guidance for suitable detectors, and summarizes their general characteristics, e.g., dose linearity, stability, dose rate linearity, and leakage. The guidance for dose linearity stipulates it to be “better than 0.1% over an absorbed dose range of at least three orders of magnitude”. The CoP did not provide any methodology for the measurement of dose linearity. The aim of our multicenter experimental study was to verify the guidance given in TRS-483 for dose linearity applying two alternative methods, using a large number of suitable detectors recommended in TRS-483 for small field dosimetry.
