Abstract

We achieved 42% counting efficiency for ⁹²P dried onto nitrocellulose filters using an end window Geiger detector and fixed geometry. This efficiency is greater than those previously reported. The counting efficiency was improved by using a high atomic number backing metal on which the filter is mounted.
