a.. Study of the sensitivity, quality dependence, anc maximim range of the film badge; and b. A cross-calibration study. | . Some 15 different AEC installations participated, and the [findings show that most of these installations are able to get a fair ddgree of ‘precision in measuring and interpreting gammaand x-ray radiation doses over a Wide range of energies and intensities. The survey hasfbeen im- portant in pointing out areas where improvements may be initiajfed in order to reauce inaccuracies in filmdosimeter measurements. | 2. Testing of Radioactive Electric Cells. Tests were mage of two + Model E-50 electric cells of the radioactive scurce type manuffctured by the Radiation Research Corporation of West Palm Beach, Florfda. are the first cellsof this type which have appeared onthe These a ket. Pre- liminary results indicate that the load characteristics are bekter than those claimed by the manufacturer. However, the voltage of thhk cells when no load is applied shcwed seme cependence on humidity ccenpitions. It is expected that electric cells cf the racioactive scurce e will and wide appliceticn in low current devices where long tb storage and smal] battery dimensions are required.
