The gamma-gamma sum peak method has been applied to the measurement of the total attenuation factors G22, in different concentrations of biological material, bovine serum albumin (BSA) using 133Ba as a probe. It is observed that G22 is inversely proportional to the correlation time of the two cascade radiations and to the concentration of biological sample surrounding the probe.
γ-γ和峰法已被应用于使用¹³³Ba作为探针测量不同浓度生物材料牛血清白蛋白（BSA）中的总衰减因子G22。据观察，G22与两个级联辐射的相关时间以及探针周围生物样品的浓度成反比。
