Abstract
We describe a new technique for nuclear-radiation spectrometry and identification by the pulse's shape in CsI(Tl) scintillators. The specific α-activity of soil samples taken from the Adit 139 and the Southeast Trace of the Semipalatinsk Test Range was determined by the method of α-particle identification in a CsI(Tl) crystal at a 1-MeV detection threshold. The results were compared to the data obtained using radiochemical separation.
