Computer methods of recognition and analysis of X-ray and gamma radiation parameters

Abstract

The rapid development of computer technologies makes it possible to use computer methods for spectral analysis of X-ray and gamma radiation, where analog electronics have been traditionally used. One of the difficulties in obtaining data from radiation detectors is the very high frequency of signal registration. However, the use of special devices called digitizers allows us to acquire, digitize and send data to a computer system at a sufficient speed. Large data arrays obtained during experiments reflect the characteristics of spectrometric signals. It is possible to recognize the registration of radiation quanta in the detector, as well as to draw conclusions about the quantitative characteristics of radiation with the help of computer methods, mathematical calculations and special algorithms.

The overview of the main methods of obtaining data in digital form for further computer analysis, namely by conducting real experiments on special equipment and by means of computer modeling (simulation) is presented in the article. Several existing methods for recognition and analysis of individual radiation particles based on the shape of the signal are described, also the methods and the software algorithms for analyzing the parameters of X-ray and gamma radiation are implemented. The computer program, that is capable of simulating data with given characteristics and can perform recognition and analysis of gamma quanta based on the loaded data, has been developed as a part of the research. The program also allows visualizing the results and checking the efficiency of the methods. The conclusions about potential directions for further research have been made.
