摘要

用末端能量为37mev的轫致辐射，测量了切尔诺贝利核电站2号机组结构材料的γ-能谱。利用57Co和58Co活性比，确定了镍和钴的质量比。利用所得数据和样品中60Co活性的测定，建立了一种测定63Ni活性的方法。对所建立的方法进行了放射化学验证，并获得了光谱和放射化学方法获得的63Ni活度的良好定量一致性。

Determination of 63Ni activity in NPP construction materials

The γ-spectra were measured of the structural materials of the 2nd unit of the Chornobyl NPP which were irradiated by bremsstrahlung with end-point energy 37 MeV. Using the ratio of the 57Co and 58Co activities, the nickel and cobalt masses ratio was determined. Using the obtained data and the measured 60Co activity in the studied samples, a method for determining of the 63Ni activity was developed. Radiochemical validation of the created method was performed and good quantitative agreement of 63Ni activities obtained by spectroscopic and radiochemical methods was obtained.
