Ukraine fights fires in Chernobyl zone, says no radiation jump

KIEV (Reuters) - Local authorities in Ukraine have dismissed residents' concerns that forest fires near the Chernobyl nuclear power station have led to unsafe radiation levels.

The radiation levels in the capital Kiev and the exclusion zone established around the plant in 1986, after an explosion there that caused the world's worst nuclear accident, "did not exceed natural background levels", the zone's authorities said.
