Abstract
The subject of the invention is a UV dosimeter suitable for visual evaluation, which is consisted of a light-sensitive layer on a carrier and a cover layer. The thickness of the light-sensitive layer is 10-40 &mgr;m, the concentration is 95-105 g/dm,and calculated to the volume of the suspension it contains in a water bloated high molecular weight polymer amenable to hardening 0,004-0,2 mole/dm,of argentic (I) oxalate, 0,0014-0,07 mole/dm,of water soluble multivalent metallic oxalate and 0,00044-0,006 mole/dm,of complexing additive. The light-sensitive layer is fitted with a cover layer, which is light-transmitting in the UVB range excluding the humidity of the air.
