## Abstract

Mass attenuation coefficients μ of milk sample have been studied by using gamma radiation at energy 662keV. The results have been presented in a graphical form. The graph of path length (cm) V/s particle intensity shows linearity. The points are fitted with least square method. The slope there graphs gives the value of the liner absorption coefficient. The density of milk sample at different concentrations V/s attenuation coefficients shows that attenuation coefficients decreases exponentially with increasing the density and confirms the interaction of gamma radiations with various concentrations of milk sample The mass attenuation coefficient usually depends upon the density and the concentration of the milk samples. Exponential decay was observed. This validates the gamma absorption law.
