[Physicotechnical and dosimetric support of human whole-body irradiation in a standard medical source of photon radiation].

The paper is concerned with physicotechnical and dosimetric support of technology of therapeutic whole-body irradiation on a serial gamma apparatus ROKUS, with which a majority of radiological institutions in the USSR are fit out. Technology consists of the following procedures: patient positioning with relation to a source with a horizontal axis of radiation. Correction of dose distribution by means of a three-element compensator taking into account patient's constitutional peculiarities and preradiation preparation data; double irradiation in the bilateral regimen in the supine position.

[Evaluation of the efficiency of the shaping of brehmstrahlung beams on electron accelerators].

Proceeding from analysis of the influence of parameters of the target-filter system on radiation-physical characteristics of braking radiation, some recommendations were issued for assessment of the efficacy of the forming systems of medical accelerators of electrons. A new criterion--a coefficient of the forming system efficacy--was introduced, characterizing a beam formation tract with relation to a whole set of radiotherapeutic problems.

[Dosimetric characteristics of encapsulated 125I sources for interstitial radiation therapy].

Thermoluminescent dosimetry in the Mix-D material was used to study the dosimetric characteristics of discrete sources in the form of titanium and nylon capsules, sizes 0.8 X 2.5 and 1.
