Faiman, Laurence (2009) Alkaline erosion of CR 39 polymer surfaces. Radiation Physics and Chemistry 78 (1), pp. 69-76. ISSN 0969-806X.Full text not available from this repository.
We have investigated the mechanism of erosion of CR 39 polymer in alkaline environments. We observed the kinetics of absorption of water and methanol into both unirradiated and γ-irradiated samples. We use a capillary model to interpret our results. We etched our samples in both KOH solutions, and KOH solutions doped with methanol. Etch rate was desensitizing to γ-irradiation when KOH concentration approached saturation, but KOH solutions doped with methanol were not desensitizing, unlike with nuclear tracks. We account for this difference.
