Safecast, crowdsourced radiation monitoring project, logs 10 million data points

The crowdsourced radiation monitoring project Safecast, which was launched in the weeks after the Fukushima nuclear disaster in Japan, has reached a big milestone: they have collected and published over 10,000,000 individual data points.


  1. I need to see if my area is mapped out radiation wise. Learned recently all our ground water is polluted with Radium and other nasty crap thanks to the Northrop Gruman plant being in town and the fact it’s cheaper to pay a fine illegally dumping than actually being responsible. Kind of a local mess, high cancer rates and many other health maladies, for example I have weird skin issues where I peel all rear round like a bad sun burn and severe tooth issues where they just got super stupid loose and fragile. I used to drink the water. 

    Waiting on the class action suit. 

  2. I love the idea of this project – it’s  a great representation of what crowdsourcing efforts can accomplish. It also allows ANYONE to access REAL numbers about the state of Fukushima disaster affected areas, and many parts of the world in general.

    However, while such raw data is great and bias free, the lack of context may be risky. The website shows the readings on a (what to me seems as arbitrarily chosen) color-coded scale. If one doesn’t read on effects of radiation and only uses the information from this project to form their opinion, they might think that some areas have very dangerously high levels of radiation, simply because they are marked red. Even though there are many areas in the world where the natural occurring radiation exceeds the values that we consider “normal” by hundreds of times.

    Also: given the equipment that these crowd-sourced stations use, you are pretty much limited to the detection of gamma radiation. Given the nature of beta and alpha radiation, you’d need a significantly more serious setup to measure their presence in the environment. So in the end your picture is incomplete. But again, it’s definitely better than nothing and I personally think it’s a step in a right direction.
