Safecast is a volunteer driven non-profit organization whose goal is to create useful, accessible, and granular environmental data for public information and research. Begun in response to the nuclear disaster in Japan in March, 2011, Safecast collects radiation and other environmental data from all over the world. All Safecast data is published, free of charge, under a CC0 designation.
Safecast is apolitical, and takes no position either for or against nuclear power. Safecast is pro-data and committed to giving people accurate information they can use to help make their own informed decisions. Safecast is funded by individuals, grants, and charitable foundations, however financial contributors and donors have no input on Safecast methods or mission.
Data is collected primarily via the Safecast sensor network. Measurements are taken free of charge. Safecast does not assign volunteers areas to be measured, but each data contributor is free to measure areas they consider worthwhile.
Safecast is a registered trademark and can not be used without permission.
The data collection effort is crowdsourced by volunteers who are widely distributed geographically. Several layers of quality control are in place, and best practices are followed. No warranties or guarantees are provided, however.
