Abstract
An improved shielding structure for providing shielding from X-ray and gamma radiation, containing at least two, and possibly three layers of material, provided in specific order from the side in which X-ray or gamma radiation is received. The first layer in order has K-edge and L.sub.I -edge levels of a first range. The second layer in order has K-edge levels between the K-edge and L.sub.I -edge levels, and lower than a secondary radiation level which is emitted by the first layer. A third layer in order has K-edge levels between the K-edge and L.sub.I -edge levels of the second layer. Materials such as uranium, lead, and gold, among others, may be used in the first layer. Materials such as tin and indium, among others, may be used in the second layer. Materials such as zinc, copper, nickel, and chromium, among others, may be used in the third layer.
