Since the March 11, 2011, meltdowns, radiation and environmental sensor engineer Pieter Franken, a researcher at Keio University in Japan (Wide Project), and Joi Ito, the director of the MIT Media Lab, founded Citizen Science, a network of citizen scientists who monitor radiation levels throughout Fukushima Prefecture with Geiger counters.
” “What we’ve come to determine in Fukushima is that radiation levels are spotty. They can vary from street corner to street corner. We’ve also been able to determine that the levels over the last five years have reduced, partly because of half life of cesium, and because of environmental factors. We’ve also seen an increase in official government data being released in a similar style to Safecast’s drive-by method versus spot checking.”
According to Franken, “There is no safe dose of radiation as it’s debated by scientists; the higher the level, the higher the risk is that it will trigger a cancer. Though, at low levels the risk is much smaller, it is not zero. However, irrespectively of what we do, we will all be exposed to naturally occurring radiation. This varies worldwide a little, but in general you could say that if you’re exposed to those levels you’re not worse off than anywhere else. That level,” he says, “is somewhere between .05-.3 uSv/hr.”
“When Fukushima happened all of my education led to this moment,” said Joe Moross, a Tokyo-based radiation and environmental sensor engineer with 35 years of experience in radiation and environmental sensing in the U.S. and Japan. He has voluntarily driven and measured over 50,000 km [31,000 miles]. “I fit in this crisis better than I have ever before. Being trained in nuclear physics, and sensor technology, this is what I’ve been made for. One of the biggest problems in Fukushima is the anxiety and the uncertainty that people are suffering from the incident. I think what were doing is trying to alleviate that by giving them ways to educate themselves about the problem and giving them solutions where they can be empowered to do something about it, as a opposed to just going along with the current of the crisis.” ”
