Safecast is a global project working to empower people with data, primarily by mapping radiation levels and building a sensor network, enabling people to both contribute and freely use the data collected.
After the 3/11 earthquake and resulting nuclear situation at Fukushima Diachi it became clear that people wanted more data than what was available. Through joint efforts with partners such as International Medcom and Keio University, Safecast has been building a radiation sensor network comprised of static and mobile sensors actively being deployed around Japan – both near the exclusion zone and elsewhere in the country.

The Safecast Map depicts over 1,000,000 radiation data points (13th November 2011) collected by the Safecast team (there are also other maps).
