KIEV, July 9. /TASS/. A wildfire raging in the exclusion zone of the Chernobyl nuclear plant for the ninth day in a row poses a threat of radiation spread to big distances, a Ukrainian expert said on Thursday.

"The fire in the exclusion zone is highly dangerous, especially in the current weather conditions. High air temperatures instigates further blaze," Tatiana Timochko, the head of the Ukrainian Environmental League, told GolosUA.

In her words, ground fire burns upper layers of soil, which accumulate radionuclides. "This ash later is blown by the wind to long distances, which poses a danger of radiation spread over big territories, since this ash later falls out on plants, soils, waters," she said, adding that the Chernobyl fire might harm ecology and human health both in adjacent and distant areas.

"Naturally, radionuclide concentrations in areas far from the epicenter may not exceed natural background levels. But in adjacent area, it is a real danger. People may eat contaminated products," Timochko said.
