I'd suggest that you read up and learn what this means because the past "spiked"elevations of Fukushima radiation we see coming across the ocean on the jet stream are becoming the norm in Washington State. Increased cancer risks from constant exposure to these levels are real, in our state now, and increase with rain. As a reference, 20 CPM is the limit for normal workers at a nuclear facility, 100 CPM is the official "adjusted" limit for workers at the Fukushima plant. What these charts show you are that we are being exposed to right now well exceed what TEPCO thinks is a safe 'adjusted" exposure level of radiation even for workers at their own disaster of a nuclear facility..

No need to panic, but this is worth keeping an eye on due to the trend. Check out the Spokane readings, scary!
