Something not right here; the guy refused to say where he found the substance, but the authorities can state for certain it was found on the site of a Nazi factory? "A treasure hunting German pensioner has discovered a lump of radioactive material the Nazis were using to build an atomic bomb during the Second World War, according to police sources. Bernd Thälmann, 64, from Brandenburg, reportedly found the uranium-based object near to the site of a secret Third Reich factory that was destroyed by 16,000 RAF bombs. When Thälmann found the clump of material last Friday he triggered a major safety alert and found himself at the centre of a criminal probe for the 'illegal use of radioactive substances'. Thälmann originally took the mysterious, metal-like lump back to his home. Although it appeared to be metal it was not magnetic. As he researched it on the Internet he became alarmed and called the police. Together with the fire brigade a cordon was thrown around his home and those of 15 neighbours. Experts wearing anti-radiation suits used specialist equipment to determine that his find was indeed radioactive. It was packaged into a lead lined box and taken away. Experts say it was part of the Nazi atom bomb project that was dispersed into the countryside after one of the bombing raids to level the plant. Thälmann has refused to tell police exactly where he found it because he intends to return to the site in future for further expeditions. Prosecutors have not yet decided whether to press charges against him." German street evacuated after radioactive material found | Daily Mail Online

"Mother never pregnant, baby never born." This was the code phrase the USSBS nuclear research teams sent back to the US after investigating the Nazi bomb efforts.
