- A gamma ray spectrum stripping method has been adapted to a Ge spectrometer for in situ measurements of exposure rates in air. This method involves subtracting out from a collected spectrum those counts that represent cosmic-ray events or partial absorption of gamma rays in the detector. The resultant total absorption spectrum is converted to flux incident at the detector, which is then used to compute exposure in air. The appropriate stripping and flux conversion parameters were determined by calibrating the detector for both full absorption peak and partial absorption continuum efficiency for parallel incident flux. This technique has particular application in indoor radiation measurements, where separate estimates of the gamma and cosmic ray exposure rates are desired and can also be used for deriving the energy distribution of a gamma-radiation field. 12 references, 4 figures, 2 tables.
