George T. Reynolds, Russian espionage,
shots Ruth and Ray, 1953

"Using the ionizing radiation survey data reported for shots Ruth and Ray as measures of the probable ionizing radiation levels produced consequent to proof of the 200 tons TNT-equivalent uranium hydride Mark II experimental device conducted at the Port Chicago Naval Magazine it is readily apparent that even the two men who survived the Port Chicago explosion at 1,000 feet under the rubble of the Joiner Shop, at the shore end of the pier, would probably not have suffered adverse short-term health consequences as the result of ionizing radiation exposure, prompt gamma nor subsequently from any local radioactive fallout."
