Distribution of emission results in pollution of environmental district and an additional irradiation of the population, therefore there is a need of a society for the control of structure radioactive нуклидов emission of the atomic power station, and also in the control of pollution by sharing substances. A concrete object of research is radiation of components of emission which can be used for their identification and quantitative measurement. It is naturally supplemented with a problem of remote revealing of sharing materials which can be uncontrolled in the image in an environment. The purpose of work - to confirm an opportunity of creation of a technique of the control of emission of the atomic power station, additional to working, with use withoutprobe a method of scale - spectroscopy and to offer methods of remote detection of sharing materials. Method of research is the analysis of radiations радионуклидов which are transported in the gazo-aerosol form on pipelines of system of special gas of claim of reactor block , and opportunities of use of existing scales - spectrometers for construction of a technique of monitoring. Mathematical modelling procedure of registration of scale - radiation outside of the pipeline of system of special gas of claim when in middle radioactive gases and the aerosols making emission are transported is executed. External radiation from a pipe develops of the weakened scale - radiation radionuclide emission and brake radiation from of beta-active nuclides. For research of transformation of a spectrum of scale - radiation in a point of accommodation of detectors computer codes G-TUBE иi PENELOPE are used, and the nuclear data were received from known electronic database JEF PC. For experimental check of elements of the developed technique the laboratory stand - simulator of sources of radiation of the big sizes with which help it is possible to model linear or flat sources with free distribution of activity is designed. Preliminary experimental researches of an active method of remote revealing 235U with the help of short impulse the neutron generator of the big stream are carried out also. The received results allow to finish development of a technique of remote revealing 235U with use of the pulse neutron generator. Product Description popup.authors popup.nrat_date 2020-04-02 Close
