Abstract

1,147,918. Radiation absorbing materials. GIKEN KOGYO K.K. 20 March, 1968, No. 13592/68. Heading G6R. An X-ray absorbing material includes compounds of lead, iron and calcium. Photoelectric emission of electrons occurs when X-rays are incident on the material. The resultant orbital electron charges, within the material, cause the emission of further X-rays of reduced energy. In addition, Compton scattering of the incident X-rays also takes place. The material may be mixed with the mortar of shielding walls.
