The AMA statisticians clearly had no idea that anyone would ever use the PhysPop values to evaluate the impact of medical radiation upon cancer mortality, by Census Divisions. In addition, we are totally confident that the mortality rates by Census Divisions, collected for Vital Statistics by the U.S. Government, ALSO are absolutely free from bias with respect to whether medical xrays have a big or a small impact on cancer mortality, by Census Divisions. One should go where the trustworthy data are, and we did. It would make good sense to avoid an exercise in SELF-defeat. The stakes for posterity are very high.
