Shielding nano- and microcomposites have emerged as a promising solution in the constantly growing requirements and expectations in the field of radiological protection. The majority of gamma and X-ray shielding nanocomposites are based on polymers due to lightweight, low cost and flexibility as the inviting features in comparison to traditional lead shields. Taking this into consideration, the following study proposes gamma-ray shielding composites characterized by their susceptibility to shape change using the heat and manual pressure. The paraffin-based composites were filled with pure lead and bismuth particles (Bi and Pb, in one mass fraction: 10 wt%) as well as it's oxides: bismuth (III) oxide (Bi
