A Vietnamese man was detained in Ukraine’s capital city Kiev on Saturday after a clock in his baggage triggered a radiation detector at a local airport.
Russian media quoted Ukraine authorities as saying on Monday that the man, whose identity was not revealed, was checking in for a flight to Moscow at Boryspil International Airport when the machine went off.
His baggage’s radiation level was measured at 2.5 millisieverts (mSv) per hour, according to the agency.
The average dose of radiation per year is 6.2 mSv and exposure to 50 mSv is enough to cause a change in blood chemistry, The Moscow Times quoted data from the US Environmental Protection Agency as saying.
The man reportedly told the border guard agency that he had bought the tabletop clock, believed to have been produced in 1984, at a local market.
The case has been reported to the Ukraine's Interior Ministry, the agency said.
