| Zusammenfassung |
| A personal UV dosimeter that can quantitatively assess high exposure solar
UVA exposures has been developed. The chemical polyphenylene oxide has been
previously reported on its ability to measure high UVB exposures. This
current research has found that polyphenylene oxide, cast in thin film form,
is responsive to both the UVA and UVB parts of the solar spectrum. Further
to this, the UVB wavelengths were filtered out with the use of mylar. This
combined system responded to the UVA wavelengths only and underwent a change
in optical absorbance as a result of UVA exposure. Preliminary results
indicate that this UVA dosimeter saturates steadily when exposed to sunlight
and can measure exposures of more than 20 MJ/m2 of solar UVA radiation
with an uncertainty level of no more than ±5%. |
