Earthquake Recap: What Worked, What Didn't

Safecast was formed in reaction to the Fukushima Nuclear Powerplant Disaster, which was caused by the magnitude 9.0 Tōhoku earthquake and tsunami of March 11, 2011. Specifically, our project was begun because of the lack of publicly available data regarding the accident’s impacts and the condition of the nuclear reactors themselves in the days and weeks following the start…

Notes from the road: Safecasting Iceland and France

During a recent family visit to Iceland and France this July, I took my bGeigie along, and in the course of a few weeks, this has allowed me to send about 50,000 measurements to the Safecast database, during many drives. Once you get into the habit of hanging the bGeigie on the outside of your car, it is…

Regarding Radiation From Air Travel

[:en]Last week VOX posted an article about radiation from air travel which caught some attention and immediately people started asking us for related data. For the past several years we’ve been logging radiation readings during flights so we have a significant amount of measurements relating specifically to this. We haven’t added these “flight” measurements to…

Safecast Code

We’ve been thinking about what describes the Safecast project as a whole, and came up with a list of 10 things that we try to incorporate into all of our efforts. This is something like our code of conduct, what are we doing, what should we be doing. We try to check ourselves against this…

Decon or Con? How is remediation being managed, and how effective is it?

HOW EFFECTIVE IS DECONTAMINATION ANYWAY? Does the Japanese government have a clear plan for decontaminating Fukushima Prefecture? Are the aims they’ve stated really feasible? Is anyone really able to keep track of the changing standards and guidelines? Lately the ministries tasked with managing this work, as well as spokespersons from various corners, seem to be…

Why is "Is it safe?" a hard question?

We are getting a lot of questions, both at info@safecast.org and through the Safecast group from concerned people – they all try to understand some aspect of radiation or another. And of course, many people ask similar questions, but without doubt the most often asked question is “Is [something] safe?” or a variation of it.…

Safecast at Stanford's Medicine X conference

I gave a presentation about Safecast at the Medicine X conference at Stanford today. There was a mix up with some of my slides and I’m not sure if I hit all the points I wanted to, and several people asked me afterwards if the presentation would be online so I thought I’d post it…
