PROPERTIES OF WELL CRYSTALS AS GAMMA-RAY DETECTORS.
Abstract
Several parameters were investigated for gamma-ray counting with a 3 x 3-inch NaI(T1) well-type scintillation detector. For normally encountered gamma-ray energies, volumes from 1 to 3 ml (using a 10-ml vial) can be counted with little efficiency loss; for standardization a 2-ml volume is proposed. Instrument response when counting showed essentially no efficiency loss for dead times up to 20 percent; for standardization a dead time below 10 percent is proposed. A set of equations based on peak areas was formulated for the unscrambling of composite spectra, and a least squares solution to these equations is provided. Resolution of either set of equations requires a computer. (Author)
