A radiation shield is being designed with two materials having mass attenuation coefcients of 0.05..


A radiation shelter is substance purposed delay two representatives having bulk leanness coefcients of 0.05 and 0.01 cm2/g. If 30% of the radiation shelter consists of representative 1% and 70% of the radiation shelter consists of representative 2, what is the whole bulk leanness coefcient for the shield?
