Gas production due to alpha particle degradation of polyethylene and polyvinylchloride

Developing radiation tolerant polymer nanocomposites using C60as an additive

“…Furthermore, decomposition of the LLDPE hydrocarbon has the potential to generate hydrogen gas that can accumulate over time, creating a flammability and over-pressurization hazard in closed environments. 10 While polymer durability and puncture resistance have improved in recent years through the use of various additives 11,12 and metallocene catalysts 13,14,15 commercial availability of radiation tolerant polymers remains scarce. Recently, polymer nanocomposites based on various forms of carbon (e.g.…”

“…In this interim state, LLDPE also undergoes rapid degradation especially when in close contact with a sources. 10 This degradation can cause the bags to become brittle and susceptible to puncturing, which can result in radiological contamination to surrounding areas. To mitigate this risk, the current practice is to periodically repackage the waste in new LLDPE bags.…”
