Microsieverts.net Lets You Visualize Radiation Levels

In addition to the unspeakable sadness of Japan’s disaster, people in Japan have also been overwhelmed by a tsunami of information about what is happening in the aftermath.  To counter this, many have turned their tech creativity and savvy to provide applications to help make sense of things. First, we saw simulations of the quake and the damage.  Last week saw a number of mapping and communication applications to help survivors connect with people and resources in affected areas.  And now at http://microsievert.net/ is a site that offers a simple yet stunning visualization of how radiation – measured in microsieverts – is being released in key areas in Japan, and how these compare to recognized levels of safety and risk.

The site depicts the radiation levels ranging from natural to “emergency evacuation” and lines them up alongside current measurements being taken at 30 km from the Fukushima Daiichi Plant as well as various monitoring points in Gunma, Saitama, Tochigi, Tokyo and Kanagawa.

Simple English translation below – but better to view the live site. If you are wondering how these levels translate, the Japan Times just published its own map.
