查询词典 detector

It is suggested by our test work on radon mapping of geology that there is a good coincidence between the data got from gamma-ray spectrometer and radon monitor and the U、Th、Ra、K data got from indoor gamma-ray spectrometer and radiochemistry method; the data of gamma-ray spectrometer and radon monitor are also comparative to the 1∶20 ten thousand geochemistry data of U、Th、 Ra (calculated by the equilibrium coefficient between U and Ra) and radon concentrations measured by solid state nuclear track detector .
