SubscribeUnaware of the small bomb he was holding, Mastick snapped the slender neck of the vial. It made a small, popping sound in the quiet laboratory. Instantly the material spewed out of the bottle and onto the wall in front of him. Some of the solution ricocheted back into his mouth, flooding his lips and tongue with a metallic taste.
Not overly alarmed, Mastick replaced the vial in its wooden container. Then he trotted across the hard-packed ground of the technical area to knock on the door of Dr. Hempelmann's first-aid station. He had just swallowed a significant amount of the world's supply of plutonium. "I could taste the acid so I knew perfectly well I had a little bit of plutonium in my mouth," he said in an interview in 1995.
IN MAY 1946, six male employees of the Metallurgical Laboratory of the Manhattan Engineer District in Chicago drank a water solution containing about 0.18 nanocurie of plutonium239 (Pu239). The purpose of this study was to investigate the gastrointestinal absorption and fecal excretion rate of ingested plutonium. Researchers also hoped to use the results to improve the interpretation of previously collected data on persons occupationally exposed to plutonium. Participation in this experiment was voluntary, and the amounts of plutonium ingested were sufficiently low to be barely detectable in urine and feces with instrumentation available in 1946. At least two of the subjects were still alive in 1994.
