Webenergy NaI probe efficiency for I-125 ~ 13%. Survey meters equipped with G-M pancake/frisker (15.5 cm2 area) or standard cylindrical style G-M probes are very inefficient (very low counting efficiencies) for the detection of low-energy I-125 gamma rays. G-M probes are only effective for gross I-125 contamination. [G-M efficiency ~ 0.5% at 1 cm]. WebNaI(Tl) scintillator is the standard and the most widely used detectors for gamma ray detection.The intrinsic photopeak efficiency is the probability of any gamma ray incident on the crystal being recorded in the photopeak of the spectrum. Intrinsic efficiency depends on source to detector distance (d) and optimizes after… Show more the island athol fugard script pdf
