AMSTERDAM (Reuters) - A Dutch person who stayed at a London hotel where former Russia spy Alexander Litvinenko met contacts before he died has tested positive for polonium 210, Dutch authorities said on Friday.

Litvinenko died of radiation poisoning in a London hospital on Nov. 23 after exposure to the highly toxic isotope.

"This person has a very, very low level of polonium 210. It is lower than what a person would receive from polonium in tobacco and food," said Wilbert Ransz, spokesman for the Dutch National Institute for Public Health and Environment.

He said the person, whom he declined to identify, was among 24 Dutch people who stayed at the Millennium Hotel between Oct. 31 and Nov. 2. They were called in for testing earlier this month and one was found to have traces of the radioactive substance.

The person would be examined again after about two months and the expectation was that the level of polonium would be lower, said Ransz.

Litvinenko met Russian citizens at the Millennium Hotel on Nov. 1, the day he fell ill.

In a deathbed statement issued by associates after his death, he accused Russian President Vladimir Putin of ordering his killing. The Kremlin has dismissed the allegation.

His death has led to a five-nation police investigation and damaged the Kremlin's reputation, despite its denials of involvement.
