Can you clarify my understanding of figure 1. It says "UK fallout dose rates" -- which I assume to be reasonably constant over the entirety of the U.K. To get the total dose rate at a location in the U.K. one would have to add the local background dose rate. In Cornwall in 1963, we would add the fallout dose rate of 0.15 mSv/yr to the background dose rate of 7.8 mSv/yr
That's my understanding too. The figure is from Allison's Radiation and Reason which I strongly recommend although I put a lot more emphasis on the dynamics of DNA repair than he does. The fallout radiation would be almost all Cesium-137 which is not present in natural background. I assume that's how they separated the fallout from other sources.
Maybe 60 Minutes on new CBS.
