Gamma-spectra corrected for backscatter and background
NaI(Tl) scintillator detectors have been exposed to gamma rays from 8 different point sources from different directions. Background and backscatter of gamma-rays from the surroundings have been subtracted in order to produce clean spectra. By adding spectra obtained from exposures from different directions it is possible to generate the detector response to any radiation field. The obtained results are to be used for determing the dose or kerma rates equivalent to measured gamma ray spectra.
