Abstract

Abstract Only

The suitability of CR-39 (poly[allyl diglycol carbonate]) for low-dose solar UV ocular dosimetry was invetigated and compared with polysulfone film. the CR-39 was sourced from two suppliers and cut into indicidual dosimeters and contact lenses. All CR-39 and polysulfone dosimeters were exposed to sunlight (0-9 minimal erthemal dose). After exposure, CR-39 dosimeters were quantified by spectrophotometric transmittance measurements at 400 nm and 720 nm. Post-exposed polysulfone dosimeters were analyzed for change in absorbance by spectrophotometry at 330 nm. The CR-39, in the form of individual dosimeters and as contact lenses, was not capable of accurate dose assessment for the dose range considered. On the other hand, polysulfone was found to be a reliable sodimeter over the same dose range.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
