FIELD: measurement technology; physics.
SUBSTANCE: invention relates to the field of radiation therapy with the use of protons and heavy ions for the treatment and can be used for practical dosimetry when determining the absorbed dose from a radiotherapeutic proton beam in a tissue-equivalent phantom for medical purposes. Summary of invention is in the fact that the energy release from ionizing radiation measurement is carried out by direct measurement of the particle mean free path by the Bragg peak to determine the absorbed dose from the calculated run-energy ratio in the energy release region luminescence visualization by a matrix CCD TV photodetector with interfacing optics, using the pixels combination and the television frames addition modes.
EFFECT: increase in the absorbed dose measuring accuracy from a radiotherapeutic protons beam in a tissue-equivalent phantom.
