ABSTRACT
ABSTRACT: The aim of this work to calculate the counting efficiency of NaI(Tl) 2x2 well scintillation detector (Canberra Inc.) .The advantage of this type detector its high efficiency which used to determination the low level of radiation as natural occurring radioactive material NORM.The gamma attenuation coefficients of natural radioisotopes and its daughters were calculated to find the three components of counting efficiency as shown in (Table 1). The (Table 2) presents the values of the counting efficiencies and plotted the graph as the aim of this study.
