Organisations of Rosatom have created several neutron generators for space exploration, medicine and law enforcement. Medvedev tested the operation of one of such devices putting his hand to a small panel. “Clear” – the test result appeared in a second. Thus the device checked whether the person has held explosives over the last few days. Asked by the prime minister about the test precision, the experts have assured him that it can detect in six seconds 20 nanograms of a dangerous substance.
