Abstract

In this study, the effect of the concentration of carboxymethylcellulose (CMC) solution on the degradation by irradiation was investigated. The CMC solutions with different concentrations of 3%, 4%, 5%, 6% and 7% were irradiated at the doses of 5, 10, 15, 20, 25 and 30 kGy with gamma ray or electron beam, and the viscosity of CMC solution was measured. The viscosity of the CMC solutions was decreased with an increase in the irradiation dose, but the extent of the degradation by an irradiation was found to be decreased with an increase of the CMC concentration in the solution. The dependency of the irradiation sources showed that an electron beam radiation had degraded the CMC less severely than gamma ray.
