Self-adhesive elastic radiation protective coatings

Abstract

Elastic self-adhesive radiation protective coatings with high adhesive strength to various substrates have been developed and can be applied to surfaces of any shape. In terms of radiation protection properties, they surpass foreign analogues by 15–35% barite-containing at an energy of 0.059 MeV, by 8%, 30% and even 200% tungsten-containing at an energy of 0.661 MeV. In terms of cost, tungsten-containing materials are 2–3 times cheaper than foreign analogues, and barite materials are 67–109 times cheaper than foreign analogues, and 2–3.5 times cheaper than domestic ones. With an absorbed radiation dose of 2.62.107 Gy (threshold value of 105 Gy), they retain radiation-protective properties and have minor damage.
