title: Precision electronics for ionization chamber measurements.
abstract: By using commercially available units, an electrometer and an IBM personal computer, it was relatively inexpensive and simple to assemble a system which permits gamma-ray-emitting radionuclide activities to be measured in an ionization chamber with an uncertainty of +/- 0.5% and a reproducibility of +/- 0.05%.
