Here we go with more of this
. Let's run the numbers and see if I should be concerned or not.120 CPM is about equal to 1 uSv/hr for CS137
. That's 97.7 uSv/hr here in Colorado Springs. But we don't know the exact gamma energies used in Bob Nichols report, so the ratio could be different.
So we're not up to even 1 mSv/hr as of yet. Seems like much to do about nothing at the moment. When the exposure rate gets to 10 mSv/hr, then I'll start being concerned.
I'm also not convinced about the whole "cumulative effect" of radiation. To me it all comes down to biological repair rate. If your body's immune system gets destroyed and can no longer make repairs faster than things are getting damaged, then yes, you have a problem, but as long as repair stays on the plus side, biological creatures should be resistant to ionizing radiation. They were designed that way. If you ask me, there is a lot of hype out there. Time to separate fact from fiction.
