"The glaring but largely overlooked message in the radiation poisoning of former Russian spy Alexander Litvinenko is that the underworld has become expert in effectively using radioactive materials for malicious purposes. This is the first example of real or attempted radiological crime or terrorism where the perpetrators were true experts. This case should alter government's perception of radiological terrorism in the same way that 9/11 affected their overall perception of terrorism."
