A few years ago, on one of her first visits to Chernobyl, Katherine Raines went to the Red Forest, a radioactive cemetery of pine trees scorched by the nuclear accident in 1986. She was curious to see if there were bees living in the area. Research on the effect of chronic exposure to ionizing radiation on insects is limited, and some of the findings are controversial, but most experts support the idea that bees and other invertebrates are relatively resilient to radioactive stress.
Raines, a radioecologist at the University of Stirling in Scotland, didn’t spend long in that forest. In one spot there, her personal radiation dosimeter measured an environmental level of ionizing radiation of 200 microsieverts (µSv) per hour; more than a few hours of that exposure could have ...
