We can see that the calculated value of mass attenuation coefficient has a variation from its given or desired value. Factors affecting the results are: Composition of the aluminum disk; Al may be oxidized; Experimental setup is not ideal; Symmetric uncertainty. According to NIST XCOM, the standard value of mass attenuation coefficient for Aluminium is 0.07466 cm2/gm. Hence, the correction factor when taken into account gives results more close to the desired value than when calculated without the correction factor. The equation for attenuated intensity value becomes I = I0* e^{-(f*µNIST *ρ*x)}.
