As you may have heard the exclusion (evacuation) zone around the Fukushima Daiichi plant continues to be adjusted to allow people into areas with lower radiation levels, and move them out of areas with higher levels. There has been no easy way to see what these areas look like so Safecast volunteer Azby created this map showing the areas impacted. The pink areas are restricted, the orange and green areas were once restricted but now open for anyone to access.
The magi behind all things iOS in Safecast Land, Nick Dolezal, is working hard on the new version of the Safecast app (which will allow on demand refreshing of the map data) decided to whip up these alternate visualizations of the Safecast data. These maps show the frequency of samples taken – NOT READINGS OF THOSE SAMPLES – just showing how often a specific place has been measured. In this example, a location (like Fukushima) that has been measured repeatedly would show hot. Thought this was a really interesting look at the work Safecast has done over the last 2+ years.
A massive update to the iOS app just went live in the app store. If you don’t have it already you can download it here. In addition to the full Safecast database, there are new map layers showing natural background (and subtractions) as well as interpolations.
Combined with your iPhone’s GPS this continues to function as the best (only?) virtual geiger counter available. It’s free, so please consider downloading it now.
Full update notes after the jump.
Along with Tony DeVincenzi, MIT Media Lab student Samuel Luescher developed the GeoSense mapping platform to help solve many of the problems we were having visualizing our data set. Samuel recently gave a short presentation about the platform that shows just how powerful it is. We’re incredibly lucky to have brilliant developers like this on the Safecast team.
We’re incredibly excited to announce the launch of the Safecast iOS app available in the App Store now. Last year we reached out to Nick Dolezal, creator of the most amazing GeigerBot, with some questions and ideas about his app. It didn’t take long for us to realize he would be a fantastic addition to the Safecast team and he agreed. We started brainstorming on what a Safecast iOS app might look like and what it might offer. The results of those continued discussions are live now. We’re most excited about the “virtual geiger counter” aspect to this app – using the GPS on your iPhone or iPad you can quickly see readings that have been taken around you. We’ve got the full Safecast dataset on board, as well as a handful of other publicly available radiation measurement data sets which gives a comprehensive exposure map for the US and Japan, with other areas being filled in as we collect those readings. There’s also the ability to connect your own geiger counter and take readings which can be submitted back to the Safecast Database.
We feel like this will be an incredibly useful application for just about anyone to have, and hope to keep improving it’s functionality as well grow. Enjoy!
The Fukushima Government has created a world wide map of radiation measurements powered by SAFECAST radiation measurements.
Good news is that we’re working hard to expand our worldwide radiation map with Singapore, Holland, Belgium, Norway and Chernobyl.
Fukushima Prefecture. updated its website “Fukushima prefecture radiation map” on Sep. 7th and started displaying radiation levels from around the world. Twelve countries with 21 spots and 46 prefectures outside of Fukushima with 571 spots are shown with data provided by Safecast, a citizen group, so that people can compare radiation levels to the rest of the world.
The highest levels are 0.23 micro Sv/hr at Jayapura, Indonesia (June 8th) and Hong Kong, China(March 11th), and the lowest was 0.06 micro Sv/hr at Honolulu, Hawai (July 17, 2011)
This site shows a total of 4452 monitored spots within the prefecture: 570 points monitored by the prefecture and an additional 3882 spots monitored by MEXT and various.

This update has been months in the making. Our visualization rock stars Samuel Luescher & Anthony DeVincenzi at the MIT Media Lab are primarily to thank for this, as well as Paul Campbell who has been diligently cranking away on our new database and API that manages all this data
We wanted to get something out the door while our kickstarter campaign was still active (it ends in 2 days), however there are still a few bugs that we know about. Load times are a bit slow. There seems to be a delay between changing zoom and the refresh of data (1-5 seconds) which can feel like an eternity. If you’ve zoomed out far enough to see the dateline, you might not see data. We’re working on these and will have an update for this soon.
This is built on our new GeoSense platform that we’ll be releasing publicly to the world soon as well so anyone with data they want to tie to a map will be able to use. Check it out, let us know what you think. And expect it to change a bit in the coming days as well.
Last month we were excited to announce that the World Karate Organization was jumping into the pool of Safecast volunteers and would be mapping out some new territory for us and helping us test our a new version of our bGeigie, that for this specific purpose we’re calling it the “Black Belt bGeigie”. We’re excited to say we’ve begun receiving data from them already and their new coverage of Sapporo is in our database now. New ground is always exciting for us, and new ground with normal levels is even better. We’re looking forward to the next batch of data and continuing to fill in the empty spaces on our maps!
For the last few months our visualization team at MIT in Cambridge lead by Anthony DeVincenzi have been working hard on some new visualizations of our data, the first of those is live now. This has a number of improvements from our earlier maps in that you can link directly to any specific location and zoom level, see census data in Japan overlayed to get an idea how many people are in some of these areas, customize the appearance and get some pretty specific details about the measurements themselves. That’s in addition to showing off the more then 2,000,000 data points we’ve collected so far. We’re really excited about this new map, as well as what’s to come in the future. Hope this is helpful for you as well!
Earlier this week there was news that The San Onofre Nuclear Power Plant, just south of Los Angeles, was shut down due to a leak. This obviously caught our attention and luckily Safecaster Mike Outmesguine was nearby with a bGeigie and immediately drove over to measure the situation. As you can see from his readings we haven’t detected any elevated levels on the public roads closest to the plant so any leak they detected was likely contained within the plant. We’ll remeasure this area again soon and keep an eye on it, but for the moment this is fantastic news.
