Low density polyethylene film was irradiated with gamma rays from Co/sup 60/ in atmospheres of nltrous oxide and xenon. A plot of solubility (S + S's') against reciprocal of irradiation dose gives a nearly straight line in each case. The probability of crosslinking increases by 44% in N/sub 2/O as compared with vacuum irradiatlon, and increases by 10% in Xe. On the other hand, the probability of main-chain scission is scarcely affected by the gases. Therefore the increase in gel fraction due to the gases is not due to the protection against main-chain scission, but is caused mainly by the sensitization against crosslinking. Furthermore, the formation of trans vinylene unsaturation is also sensitized by the gases. (auth)
