Дозиметрия нейтронных полей терапевтического комплекса на базе циклотрона У-120

Abstract

In this work, the characteristics of the treat beam's dosimetry of fast neutrons of the U-120 cyclotron have been analyzed with the help of the ionizing method. The fast neutrons with 6, 3 MeV as medium energy have been obtained in coordination of deuterons with the target made of beryllium and are meant to be used for treating the patients with malignant neoplasms. The capacity of the dose in the beam of fast neutrons has been measured by ionization chambers of different types. The research has been done with the consideration of co-occurring gamma rays. The monitoring indices needed for calculation the duration of therapy session at given therapy dose have also been specified.
