The efficiency of a radiation shielding structure consisting of a set of alternating layers of light and heavy metals is shown to be enhanced when the layered structure is turned to a radiation source by the light metal layer. The protection efficiency is maximal at the single-period structure scheme (one light metal layer and one heavy one). The validity of the predicted regularities is confirmed by experimental results obtained using W and Al as the layered structure materials. Dependence of radiation absorption efficiency on orientation of layers relative to the source was observed also for thin three-layer W-Mo-Tl structure.
