Russia medics fear nuclear blast contamination

Two of the medics in Arkhangelsk spoke to BBC Russian about the victims' evacuation, on condition of anonymity.

Five nuclear engineers died on 8 August when an "isotope-fuel" engine blew up at the Nyonoksa test range, officials said. Six other people were injured.

President Vladimir Putin said the test involved a new weapon system.

Officials gave few details about the accident. On 14 August Russia's weather service Rosgidromet revealed that radiation levels had spiked 16 times above normal, in Severodvinsk, a city 47km (29 miles) east of Nyonoksa.

According to the official data, the radiation that reached Severodvinsk was not heavy enough to cause radiation sickness.
