Effect of container diameter on β-radiation-induced polymerization of acrylamide
Beta particles emitted by radioactive nuclei have a finite depth of penetration in a given medium and hence a certain linear energy transfer value depending upon their initial energy. This property can be utilized to achieve different rates of radiation induced reactions. Various diameter capillarie...

Summary: | Beta particles emitted by radioactive nuclei have a finite depth of penetration in a given medium and hence a certain linear energy transfer value depending upon their initial energy. This property can be utilized to achieve different rates of radiation induced reactions. Various diameter capillaries containing saline solutions of acrylamide and radioactive phosphorus‐32 were used in the experiment and the change in viscosity of acrylamide solution was used as an indicator of the amount of energy transferred. Distinctly different rates were observed which were roughly proportional to the diameters of the capillaries containing the solutions. It also appears that irradiation of the polymer solution at 80°C even in the absence of oxygen has an adverse effect on the viscosity. The experimental conditions were chosen to approximate those existing in oil reservoirs. |
