Embodiment 1
[0024] Take by weighing 255 grams (8.5wt%) of polyvinyl alcohol (PVA) resin, its degree of polymerization is 1750, 2745 grams (91.5wt%) of distilled water is placed in the flask, above-mentioned PVA resin is added into distilled water slowly, stirs while adding After the feeding is completed, continue to stir for 10-20 minutes, then heat up to 95°C, and continue to stir for 30 minutes after constant temperature. Filter the solution with a G3-G5 sand core funnel and pour it into the breast-shaped silicone rubber bag prepared in advance. The volume of the high molecular polymer solution in the capsule is 88-96% of the volume that can be accommodated in the capsule, and then the air bubbles in the solution in the capsule are removed, the silicone rubber capsule is sealed, and the sealed breast-shaped solution is housed. Put the silicone rubber bag into the breast formwork and seal it for packaging, and finally irradiate it with cobalt-60 gamma rays in the air at room temperature, ...
Embodiment 2
[0026] Take by weighing polyvinyl alcohol (PVA) resin 210 grams (7wt%) that polymerization degree is 1750, polyvinylpyrrolidone (PVP) resin 30 grams (1wt%), distilled water 2760 grams (92wt%), distilled water is placed in the flask, Slowly add the above PVA resin and PVP resin into distilled water, stir while adding, continue to stir for 10-20 minutes after the addition is complete, then heat up to 95°C, continue to stir for 30 minutes after constant temperature, and pour the solution into a G3-G5 sand core funnel After filtering, pour it into the pre-prepared breast-shaped silicone rubber capsule. The volume of the high molecular polymer solution poured into the capsule is 88-96% of the volume that can be accommodated in the capsule. Silicone rubber capsule, then put the breast-shaped silicone rubber capsule that has been sealed with the solution into the breast mold frame for sealing and packaging, and finally irradiate it with cobalt-60γ rays in the air at normal temperature...
Embodiment 3
[0028] Take by weighing polyvinyl alcohol resin 195 grams (6.5wt%) that the degree of polymerization is 1750, polyacrylamide (PAAm) resin 30 grams (1wt%), distilled water 2775 grams (92.5wt%), make by the method for embodiment 2, heat The temperature, stirring time, pouring amount are the same as in Example 2, and the absorbed dose of cobalt-60 gamma rays is 19.5kGy, and the product of the present invention is obtained.
