“…Scintillation counters, in general, and NaI (Tl) in particular are widely used in various fields of nuclear radiation detection, such as environmental studies [1,2], nuclear medicine [3], health physics [4] and high energy physics experimental [5]. The efficiency of the NaI(Tl) was Studied by many researcher [6][7][8][9][10][11] , So the experimental applications:…”

To study the effect of the shield thickness of the surrounding on the total and photo peak relativity efficiency for the NaI(Tl),two NaI(Tl) detectors (3'' × 3'') and (1.5" × 1.5") crystals are used and the radioactive source is Cs-137 which emits (0.662) MeV photons at distance of(25)cm from the detector and (146.8µci) activity.The Surrounded materials represented by cylinders of (35) cm. long, and different thicknesses (2.5, 4.4, 5.6and8.9) mm. and different diameters (11, 16 and 21.5) cm. for the steel (Iron) cylinder.For (1.5" × 1.5") and (3'' × 3'') detectors without cylinder, the total and Photo peck Relativity efficiency are (100%) relative to it selves.While, increasing of the thickness of the cylinder, the total and Photo Peak Relativity efficiency decrease for the two-size detector
