Measurement Of Cosmic Rays Intensity And Study Of It's Statistical Property

As a member of the nuclear and radiation technology center of Gansu province,my major work was devoted to the nuclear and radiation monitoring and evaluation.According to the specialrequirements of Master thesis of engineering,measurement of cosmic rays intensity and it's statistical properties investigation were chosen as my academic dissertation.It's important to chose a suitable detector in a practically nuclear and radiation monitoring.This work is mainly aimed at 2013-2015,GanSu,QingHai and NingXia in different parts of the cosmic ray intensity with altitude,geographic latitude and longitude,time,and the change of factors such as different detectors.Use portable X-ray gamma measurement instrument and high pressure ionization chamber and so on the different types of detectors to analyze statistical properties measurement and the measurement results.Measurement results show that,cosmic ray intensity increases with the increase of altitude and latitude and in the range of measuring longitude,decreases with the increase of longitude.This is consistent with the theoretical calculation results.In addition,RSS-131 meter measurement data with the theoretical calculation result on the trend and quantitative obvious consistency,compared with other measuring instrument,a wider range of energy response of RSS-131 type of measuring instrument implies that it can accurately feedback cosmic ray intensity.
