Richard Handl said that he had the radioactive elements radium, americium and uranium in his apartment in southern Sweden when police showed up and arrested him on charges of unauthorised possession of nuclear material.
Handl, 31, said he had tried for months to set up a nuclear reactor at home and kept a blog about his experiments, describing how he created a small meltdown on his stove.
Only later did he realise it might not be legal and sent a question to Sweden’s Radiation Authority, which answered by sending the police.
