Trees show harmful effects of Chernobyl nuclear radiation

Chernobyl’s legacy recorded in trees By Mark Kinver Environment reporter, BBC News Exposure to radiation from the 1986 Chernobyl accident had a lasting negative legacy on the area’s trees, a study has suggested.

Researchers said the worst effects were recorded in the “first few years” but surviving trees were left vulnerable to environmental stress, such as drought.

They added that young trees appeared to be particularly affected.

Writing in the journal Trees, the team said it was the first study to look at the impact at a landscape scale.

“Our field results were consistent with previous findings that were based on much smaller sample sizes,” explained co-author Tim Mousseau from the University of South Carolina, US.

“They are also consistent with the many reports of genetic impacts to these trees,” he told BBC News.

“Many of the trees show highly abnormal growth forms reflecting the effects of mutations and cell death resulting from radiation exposure.”…… Prof Mousseau and his team hope to follow up this study by carrying out similar work in the Fukushima region in Japan, where logging also had considerable economic importance and pine trees were widely dispersed. http://www.bbc.co.uk/news/science-environment-23619870
