Abstract
A thin film (10-40 μg cm-2) of polycarbonate treated with polyvinyl alcohol was prepared and used as a Geiger-Muller tube window. The counting efficiency of this tube for a tritium sample was 6 to 15% of that for the same source obtained by using the windowless 2π counter. A Geiger-Muller tube of 17 μg cm-2 window thickness proved satisfactory for tritium counting.
