Visual and audio guides to radiation risk
Over the past three weeks, we have been inundated with numbers and estimates of risk posed by radiation from the earthquake-damaged Fukushima Daiichi nuclear power plant in Japan.
It can be hard to put this risk into perspective. My colleague Peter Wehrwein has done it with words. If pictures or sounds help you absorb complex information, here are three good resources for understanding radiation risk:
A cartoonist named Randall Munroe who blogs at has put together a that visually explains radiation exposures and risks. (The image above is just part of the chart.) Beginning with tiny boxes representing the smallest radiation exposure鈥攕leeping next to someone, or 0.05 millionths of a sievert鈥擬unroe builds up to a fatal dose of 8 sieverts, and shows a lot in between. (A sievert鈥攁bbreviated sV and pronounced SEE-vert鈥攊s a measure of the biologic effect radiation has on people and the possible harm it can cause.)
Adam Ragusea, a reporter and associate producer for , took Munroe鈥檚 chart and . Radio Boston airs on WBUR, one of Boston鈥檚 public radio stations.
Another of the possible harm caused by different doses of radiation comes from Ellen McManis, a senior reactor operator for the Reed Research Reactor, which is owned and operated by Reed College in Portland, Oregon.
