Acrylamide–methylenebisacrylamide gels (95/5 monomer ratio) of 10, 6, and 4% total monomer concentration were subjected to from 0 to 57.6 Mrad. of ionizing radiation. With increasing radiation dosage, the gels first shrink because of further crosslinking, then rupture and break into gel particles. At a dose rate of 0.5 to 1 Mrad/sec., the gels will absorb about 5 Mrad. before degradation begins. Weaker gels (4%) will absorb more irradiation before they degrade than will stronger gels (10%).
