[Role of Radionuclide Technologies in Medicine].

The paper describes the role of radionuclide technologies among the nuclear-physical methods used in medicine. The condition and prospects of the development of nuclear technology with use of radionuclides in medicine, and in particular, the method of brachytherapy are analyzed. The analysis of the current state of applying radionuclide facilities in medicine is provided.

[Method to increase efficiency of irradiation of biological objects by electron beams].

The method has been proposed for active control of distribution of the dose caused by an electron beam passed through the medium. The method is based on the influence of magnetic field on charged particles and it allows concentrating of the absorbed dose in the prescribed area. To investigate this method the Monte-Carlo simulations were carried out for 20-70 MeV electrons in 0.
