Times Cited Count:0 Percentile:0.00(Chemistry, Physical)In recent years, the use of radiation-resistant resins of polyimide and polyether ether ketone becomes increasing as vessels for irradiation and unsealed radioisotope experiments. However, in our radiolysis experiments, the possibility of interaction between radiolysis products of water and the resin was found, suggesting concerns that the resin may affect reactions in water in radiation fields. To clarify the interaction, dichromate (CrO
) reduction and hydrogen peroxide (H
O
) formation in
-radiolysis of water were compared with and without the resin. The Cr
O
reduction amount in aqueous solution with the resin became larger than that without the resin at the same dose, indicating the promotion of Cr
O
reduction by the resin. On the other hand, the H
O
formation in pure water with and without an electron scavenger were almost independent of the presence of resin. These suggested the interaction between hydroxyl radical and the resin in contact with water in radiation fields.
