Background and Aim: In angiography, the lens of the eye may be exposed to radiation and cause cataracts. In Iran, at present, only a single film dosimeter is used under the lead-apron to evaluate individual doses. The aim of this study was to investigate the status of occupational radiation as well as the validity of measuring the dose of the whole body of individuals and eye lenses using a sin...
A prototype UVA dosimeter that is responsive to the UVA wavelengths only has been developed for measurement of personal exposures. The chemical phenothiazine, cast in thin film form and which is responsive to both the UVA (320400 nm) and UVB (280-320 nm) part of the spectrum was used and filtered with mylar. This combined system responded to the UVA wavelengths only and underwent a change in op...
A simple optical dosimeter was used to measure the light intensity in rat liver and muscle in vivo with fibers positioned at different depths to investigate whether the light penetration changed during photodynamic therapy (PDT). The results were then correlated with measurements of the three optical-interaction coefficients µ(s), µ(a) and g for wavelengths in the range 500-800 nm for PDT-treat...
