The polyrnerization of acrylamide in aqueous solution was carried out with BETA -irradiation ficilities using unsealed /sup 85/Kr gas as an internal radiation source. Irradiation experiments were made in a reaction vessel of 1- liter capacity with 290 Ci of /sup 85/Kr. The effects of dose rate, monomer concentration, and polymerization temperature on the polymerization rate were studied. The experimental results were compared with the results using /sup 137/ Cs as; source. It is observed that the polymerization rate, for either source, is proportional to the 0.55th power of dose rate and the 1st power of monomer concentration. In addition, the activation energy of polymerization is 1.8 kcal/ mol. It can be considered that there is no particular distinction in the polymerization rates due to difference in the radiation source. (auth)
