MADRID, Spain (AP) - Spain's Nuclear Safety Council says it is checking some 800 people for contamination after learning that a radioactive leak at a nuclear plant was larger than first reported.
The council says none of the 579 people scanned so far have shown signs of contamination.
The Asco I nuclear power station on the Ebro River is still working, and the council assures there is no danger to the population.
The company that controls Asco I had confirmed the leak after being alerted by Greenpeace environmental group on April 4. Greenpeace says it believes the leak occurred in November.
The Nuclear Safety Council said Tuesday it was upgrading it from a Level 1 to a Level 2 leak, on a scale of one to seven.
