Abstract :
Calculation of distributions of the absorbed dose is an important constituent of radial therapy of malignant tumours. Accuracy of such calculation substantially determines radial affect on the tumour and the result of treatment. Therefore the scientists continue to improve the methods of calculation in order to obtain a lot of information about distribution of the obsorbed dose with great accuracy. This paper is devoted to the estimation of influence of natural artificial heterogeneities in radiated area of the human body. Calculations have been carried out with the help of program complexes EPHCA and GEANT 4 (version 6.1).
