We should also remember the servicemen who died too young because of insufficient safety protocols for atomic testing.

People didn’t know any better at the time. A poor excuse, but true............

Using his own unapproved protocol, Slotin did not place any shims. ... Enrico Fermi reportedly told Slotin and others they would be "dead within a year" if they continued performing the test in that manner. Scientists referred to this flirtation with a nuclear chain reaction as "tickling the dragon's tail", based on a remark by physicist Richard Feynman.Spoiler Alert: Slotin surveyed Fermi's warning by four months.
And the innocent civilian bystanders that had no knowledge of what they were doing. Marie Curie is an example.
During her pioneering experiments, the dangers of radiation were largely unknown. Curie routinely carried vials of radioactive isotopes in her pockets and handled them with her bare hands. Because of the radioactive residue on her body, Marie Curie was interred in a lead-lined coffin. In 1995, her remains were relocated and entombed in the Panthéon in Paris, France’s national mausoleum, where she rests alongside other French luminaries. Because these materials have extremely long half-lives, this heavy exposure permanently contaminated her personal belongings. Her laboratory notebooks, recipes, and even her cookbooks remain so radioactive that they are still stored in lead-lined boxes at the French National Library, requiring protective gear to be handled. She was hot in the worst kind of way.
