This paper describes the use of NaI （Tl） scintillation spectrometer on 137Cs and 60Co

and other sources of γ-ray radiation on absorption lawchange in circumstances to the tungsten-nickel alloy materials and lead material.Fitting get through the mapping of the different energy γ-rays in different substances in the line absorption and γ-ray absorption of half the thickness

Through this two kinds material of comparison

tungsten-nickel alloy that the γ-ray absorption far higher than traditional shielding materials---lead.So

tungsten-nickel alloy can utilize and protect the ray to shield the respect in radiation effectively.we has put forward newideason mterial selection to Radiation Protection.
