Polysulphone film thickness and its effects in ultraviolet radiation dosimetry

Abstract

[Abstract]: Polysulphone film thickness and the effects on the dose calibration in ultraviolet radiation dosimetry were investigated. Compared to those obtained with the dose calibration for the 45 micrometre thick film the erythemal exposures determined from the dose calibrations for the 18, 20 and 30 micrometre thick film ranged from 33% to 45%. The absolute of the differences averaged to 22%, 37% and 19% for the 18, 20 and 30 micrometre thick respectively. The variations in the dose response of polysulphone film with different thickness have shown that the dose response is highly dependent on the film thickness and highlighted the importance of employing polysulphone film of consistent and reproducible thickness in ultraviolet photobiology research.
