Background gamma and beta radiation in Sacramento, CA, March 19, 2011. Saturday

Another radiation reading in the same spot in Sacramento, Saturday morning. No significant gamma or beta radiation was detected. If there were a significant amount of radiation, the Geiger counter would click so fast that it would sound like static. Right now, there's so little radiation that it's almost undetectable. 1 milliseivert (mSv) = 100 mR Yesterday, March 18,2011, some highly sensitive instruments in Sacramento detected very, very low levels of radioactive atoms that was identified as originating in the Fukushima plant. See the previous video for how to interpret the mR/hr. Suffice it to say that, as of today, the official line appears to be correct - that, while highly sensitive instruments may be able to detect minute amounts of radiation, there isn't anywhere near enough to be worried about. If the Fukushima reactors explode, there might be higher levels.
