The technique of measuring of relativistic proton absorbed dose in thin biological samples

The technique of blood samples irradiation by the 1 GeV protons is described. This experiment was carried out to study chromosomic aberrations induced in human lymphocytes by the low absorbed doses. The problems of measurement and calculation of the absorbed dose of protons in thin samples with necessary precision are discussed. The method of forming the uniform spatial distribution of the proton flux that crossed the samples and the technique of the beam monitoring are presented
