The Urgent Mission of RadiationWatch

RadiationWatch is an ad hoc group of concerned private individuals from around the world who have been carefully monitoring the events at the nuclear power plants in Fukushima prefecture, Japan, caused by the devasting earthquake of March 11, 2011.

The current source radiation data is spread across multiple government ministries at various levels, NGOs, and more. This official data is further enhanced by the numerous monitoring points set up by individuals. It is available to the public, anywhere. However, the data has not been collected,  standardized, and made easily available.

The central government of Japan currently has many tasks on their hands. Our aim is to assist them, as well as the Japanese public and members of the media, by providing a comprehensive list of links to the attempts being made around the world to collect and represent the available data in a readable form. Our belief: Knowledge is power.


Above all, we want to emphasize: regardless of our individual opinions regarding nuclear power, RadiationWatch as a group does not have a political agenda. Our sole aim is to make the data accessible to all. 

If you're interested in joining our urgent efforts, please add message @trebonian1 on Twitter. You will need to follow him so that he can DM you. Before you do, you must realize the absolute urgency of our task.

Let us do our small part to aid the people of Fukushima, Japan.
