" ,Demron, is effective as a radiation shield, comparable to lead in terms of g/cm2 and ,tantalum, according to the mass attenuation coefficient, against gamma, x-ray and beta emissions. For example, for 100 keV photon radiation, the mass attenuation coefficient is about 3.8 cm2/g, which means that the transmission will be down to the l/e point for a thickness of 1/33 = 0.26 g/cm*.
