Safecast is apolitical

We take no position either for or against nuclear power. Our community is inclusive and non-partisan, bringing together people of all ages and from all walks of life. Outreach activities allow us to share our experiences with individuals and groups worldwide through frequent workshops, talks, and educational programs.

Safecast is pro-data

We're 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.

Safecast is voluntary

Data is collected primarily by volunteers using Safecast designed hardware. We do not assign areas to be measured, rather each data volunteer is free to measure areas they consider worthwhile. Measurements are taken free of charge. Several layers of quality control are in place and best practices are followed, but no warranties or guarantees are provided.

At Safecast, we're proud that much of our work overlaps with the United Nations Sustainable Development Goals. The following goals are directly related to our efforts. Click on any icon for more details.

The Safecast Team

In response to Japan’s tsunami and nuclear disaster of March 2011 a group of individuals came together in an effort to address a critical public need for open, accurate, and unbiased environmental data. Setting out to collect and publish useful data relating to the levels of nuclear radiation in and around the area of the disaster in Japan, Safecast was born.

Today our growing Safecast team continues collect and publish environmental data from all over the world.
