This study was carried out to find the effect of γ-irradiation on the physical properties of alginic acid and λ-carrageenan solution. Alginic acid and λ-carrageenan aqueous solution were irradiated with Co∨60 γ-rays in dosages ranging from 3 to 100 kGy, and then the molecular weight, viscosity and color were measured. The molecular weight of alginic acid and λ-carrageenan solution were decreased as the γ-irradiation dosage increased. In addition, the viscosity of irradiated alginic acid and λ-carrageenan solution were decreased depending upon the γ-irradiation dosage, too.
