[Radiation characteristics of narrow photon beams].

The paper is concerned with an analysis of the radiation characteristics (depth doses, beam contours, radiation output) of several medical linear accelerators in the formation of high energy narrow beams (up to 2 x 2 cm). Experiments and computer-assisted numerical simulation have shown that the use of an additional collimator makes it possible to obtain characteristics of photon beam dose fields in biaxial rotation comparable to those in irradiation of small intracranial targets with proton beams at the energy of 1000 MeV.

[Results and future of the activities of the Department of Medical Radiation Physics of the Central Scientific Research Roentgenoradiology Institute of the USSR Ministry of Public Health].

The main directions of research activities, pursued in the Department of Medical Radiation Physics over 25 years, are reviewed. The staff-members have done a lot for the development of Soviet modern radiotherapeutic engineering (electron accelerators). They are devising a cyclotron complex for purely medical purposes. Investigations in fundamental dosimetry, software for radiation therapy, computer use in x-ray studies will permit research in the following directions: --physicotechnical aspects of medical use of cyclotrons; --automation of radiation therapy technology (including software and control systems); --procedures to ensure quality in radiation therapy; --dosimetric maintenance of radiobiological experiments; --computer use for analysis of medical images.

[Measurement of dose fields using different detectors].

The authors presented and analyzed the results of measurement of dose fields of photon and electron radiation using 3 types of detectors (ionization camera, Si detector and diamond detector), alternately switched on to the CADSCAN dose field analyzer. The results of a study of dose fields of inhibitory radiation at 18 MeV were indicative of the similarity of data obtained with the help of diamond and Si detectors and an ionization camera. Comparison of the results for electron radiation at 4, 17 and 20 MeV showed that data obtained with the diamond detector, coincided with absorbed dose distributions calculated on the basis of ionization measurements whereas dose accumulation values obtained with the help of the Si detector were very high.
