но и походу здесь одну историю рассказали, где и как можно "материал" достать.
Довольно она уж старая (1998), но не слыхал ни разу,
а потом как в Дубне есть много специалистов, а рядом Мичуренец... то решил вот поделиться
Это оригинал -- как всё начиналось. (англ)
пдф-версияTo obtain americium-241, David contacted smoke-detector companies and claimed that he needed a large number of the devices for a school project. One company agreed to sell him about a hundred broken detectors for a dollar apiece. (He also tried to “collect” detectors while at scout camp.) David wasn’t sure where the americium-241 was located, so he wrote to BRK Electronics in Aurora, Illinois. A customer-service representative named Beth Weber wrote back to say she’d be happy to help out with “your report.” She explained that each detector contains only a tiny amount of americium-241, which is sealed in a gold matrix “to make sure that corrosion does not break it down and release it.”
