In our previous work [1], the detector collimator of the landmine detection device has designed and optimized using gamma-rays back scattering of 241Am isotopic source with 0.06 MeV in energy and NaI(Tl) detector. In this study the effect of changing energy of gamma-rays on the landmine detection device using 192Ir source gamma-rays with 0.35 MeV in the average energy of emitted gamma-rays was evaluated by Monte Carlo method using the MCNP code. NaI(Tl) detector shield was obtained the lead cylindrical with 2 mm in thickness and 100 mm in height. NaI(Tl) detector collimator was obtained the lead cylindrical with 2 mm in thickness, 14 mm in height and the inner radius equal to the radius of the detector window. The angle of axis detector and gamma-rays emission from 192Ir source with the soil surface were obtained respectively 90 and 70 degree to obtain maximum contrast. Finally, we can say that with increasing energy of gamma-rays, contrast decreases, but if the landmine detection device is optimized, the depth of landmine detection is increased.
