[Solar elements in the control of photon irradiation parameters in radiotherapy]. / Solnechnye élementy dlia kontrolia parametrov fotonnogo izlucheniia v luchevoi terapii.

A study was made of the dosimetric characteristics of semiconductor detectors (on the basis of silicon with the p-i-n structure) and combined detectors (scintillation crystals based on CsJ/Tl combined with silicon detectors). The spectral characteristics of semiconductor and combined detectors are described. The results of levelling of hardness dependence by filtration and combination of detectors are presented; their isotropism is reviewed.

The unit is capable of providing the information on the man parameters of the radioactive sources, thus improving the reliability and accuracy when planning the treatment in radiotherapy.
