4-1 GAMMA IONIZATION CHAMBER MEASUREMENTS

The fallout samples listed are all solutions of OCC samples. Because three instruments with
varying responses were invojved in measurements during Operation Redwing, observed values
have been arbitrarily normalized linearly to a standard response of 700 x 107 * ma for 100 ug
of radium.
