![]() He was working extremely hard in a position of great responsibility." One report stated: "The patient felt well 38 months after exposure. The official reports seem to downplay the effects – the permanent impairment of vision in his left eye, or the many months it took for his sperm count to recover. ![]() Standing at Slotin's shoulder, Graves received a high dosage of radiation and became critically ill. Relatively unscathed by the accident, Schreiber went on to help re-design the way procedures like the one that killed Slotin were conducted, with a greater emphasis on safety. According to one researcher the US government "established a pattern of secrecy", in response to Slotin's death "that still persists". But there was little public discourse around what his death might mean. From this perspective, Slotin's accident was a missed opportunity a minor entry in a long history of technological wake-up calls that have been poorly recorded and at best partially examined. Niels Bohr once defined an "experiment" as "a situation where we can tell others what we have done and what we have learned". Like an experimental nuclear bomb, it was used to safely test the reactivity of a plutonium core. A little before 15:00, in the middle of one of the laboratory buildings, Graves spotted something he recognised: the "critical assembly", which was Slotin's specialism. Slotin was giving a tour to Alvin Graves, the scientist who was due to replace him. But, like Oppenheimer, in the months that followed, he came to object to the continuation of the nuclear weapons programme and had decided to go back to civilian life. He was an expert in bomb assembly and had played a central role, hand-building the "Trinity" device for the first test in July 1945, just a month before the Fat Man and Little Boy atomic bombs were dropped on Japan. ![]() On, the physicist Louis Slotin was in his final weeks of working for the Project. From this base in the desert, and under the leadership of Robert Oppenheimer, they developed the world's first atomic bombs. ".In the search for a harmonious attitude towards life, it must never be forgotten that we ourselves are both actors and spectators in the drama of existence." – Niels Bohr, physicistĭuring World War Two, the US government formed the Manhattan Project, recruiting scientists and engineers from across the world to live and work at a secret research centre in Los Alamos, New Mexico. ![]()
