title: [Means of improving and characteristics of the use of beta spectrometry of 90Sr after the Chernobyl accident].
abstract: The paper is concerned with a theoretical possibility of the use of 90Sr beta-spectrometry in a mixture of radionuclides including 137Cs, 134Cs, 144Ce and 106Ru after the Chernobyl accident. Special attention is paid to the choosing of a detector and spectrum treatment techniques as factors determining the minimum detectable activity of the method. A brief description of the spectrometric system as well as of the software used is given. The comparison of the method with traditional radiochemical and gamma-spectrometric methods has shown that it is applicable to a wide range of activities and to different objects including those of biological origin. The sources of errors are considered in detail. Approaches to the development of the method are given.
