Swedes Tested for Polonium Exposure
Three Swedes who were in London recently are being tested for polonium, the substance that killed a former Russian spy.
The three were staying at the hotel where the ex-spy was poisoned, and the radioactive substance has been found in some rooms and in personnel working in the hotel bar.
The medical authorities here say the chance of the three Swedes receiving a dangerous exposure is slight, as the level of radiation among the bar personnel was very low.
Four other Swedes who were also at London hotels where polonium has been found are not believed to have come in contact with the radioactive substance.
