Title: Fukushima birds may cope with radiation
Source: New Scientist
Date: 11 April 2012

JAPAN’S birds can breathe a little easier: the Fukushima Daiichi nuclear accident might not have a lasting impact on breeding patterns.

A 2011 study of birds near Chernobyl in Ukraine found that their sperm is being damaged by harmful reactive oxygen species, which may have been created by radiation from the country’s nuclear disaster in 1986. But according to calculations by Jim Smith at the University of Portsmouth, UK, the radiation at Chernobyl couldn’t have produced enough reactive oxygen species to explain the observed harm [...]

That doesn’t convince Anders Møller at the University of Paris-South, France, an author on the 2011 study. He points to studies that suggest declines in farming affect barn swallows but don’t stop them reproducing. [...]

But the birds aren’t home free: radiation harms wildlife in other ways, such as damaging DNA.
