natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

A virtual counter was developed to count the signals from a scintillation detector. After were processed by some electronic devices, they counted and real counter. The counts obtained both counters accumulated via different amplifier gains source-to-detector distances investigate their effects on recorded counts. results compared with those of one. It concluded that could be used radiation dete...
