In the NIMB article published by Khelidj and co-authors in 2005, they criticized one of our papers published in 1985 by stating that our radiation dose rate modeling of a PVC material predicted an infinite lifetime at low dose rates which totally ign

Nylon 6.6 containing 13C isotopic labels at specific positions along the macromolecular backbone has been subjected to extensive thermal-oxidative aging at 138 °C for time periods up to 243 days. In complementary experiments, unlabeled Nylon 6.6 was

Oxidation of organic materials typically results in the outgassing of degradation compounds. The most abundant outgassing thermal-oxidative degradation species of nylon 6.6 are known to be carbon dioxide (CO2) and ammonia (NH3). By performing acceler
