Four Infographics that Help Explain Radiation Exposure

Beware the misinformation about radiation risks, and arm yourself with these charts to better put the crisis in Fukushima in context.

In the immediate aftermath of the tsunami and the Fukushima nuclear crisis, we posted a couple of charts about the impacts of different levels of radiation. In the past few weeks, designers have had the chance to touch up those simpler efforts. Here are some of the best that should help you better understand the actual threats of radiation.

Lena Groeger, of NYU’s Studio 20 in New York, created this radiation exposure infographic on a vertical linear scale to "transform something you can't see, smell, taste or feel into something a bit more tangible." It goes a long way in giving viewers the scale of exposure.

Alexandra Muresan created Triangle Chart with Fabian Fucci to explain the overall effects of the radiation exposure rate and, more importantly, exposure time on the estimated amount of radiation received.

David McCandless, of Information is Beautiful, created this chart, which, like all of his work, the data behind the chart is publicly available.

Randall Munroe, of XKCD, created this well-circulated logarithmic box chart that contains some useful explanatory text.

The charts help put the accident at Fukushima in context, but, as Anil Dash writes, it's important to distinguish between dose and dose rate. He emphasizes that "risk is a function of the accumulated internal dose."

It's also worth pointing out the shortcomings of the familiar benchmark—the "banana equivalent dose"—which tends to oversimplify the kind of radiation exposure.

Let us know in comments if you find any other compelling visualizations that help make the complex science behind nuclear radiation exposure more comprehensible.

In the months after the Japanese bombed Pearl Harbor in 1941, President Franklin D. Roosevelt authorized the military to move Japanese-Americans into internment camps to defend the West Coats from spies.

From 1942 to 1946, an estimated 120,000 Japanese Americans, of which a vast majority were second- and third-generation citizens, were taken in their homes and forced to live in camps surrounded by armed military and barbed wire.

After the war, the decision was seen as a cruel act of racist paranoia by the American government against its own citizens.

The interment caused most of the Japanese-Americans to lose their money and homes.

The head of the 1,100-member Federal Judges Association on Monday called an emergency meeting amid concerns over President Donald Trump and Attorney General William Barr's use of the power of the Justice Department for political purposes, such as protecting a long-time friend and confidant of the president.

North Korea remains arguably the most mysterious place on Earth. Its people and modern day customs are shrouded behind a digital and physical wall of propaganda. Many people in the United States feel that North Korea is our "enemy" but almost none of us have had the opportunity to interact with an actual person who lives in, or has lived under, the country's totalitarian regime.

Even more elusive is what life is like in one of North Korea's notorious prison camps. It's been reported that millions live in horrific conditions, facing the real possibility of torture and death on a daily basis. That's what makes this question and answer session with an escaped North Korean prisoner all the more incredible to read.
