"Low Level Revision 1 1.2.6 1.2.6.3

Professor R.C.
von Borstel, Dept. of Biological Sciences, University of Alberta, Edmonton, Alberta,
Canada, in a review of "Health Effects of Low-level Radiation", by Sohei Kondo,
states (1995) that: "In another analysis that Kondo made on data of [many]
populations exposed to radon, his findings are in direct contrast to the estimates of the
US EPA... (T)he individuals exposed to radon have beneficial effects with respect to
cancer mortality. Kondo's analyses are extensive and profound." Drs. Gary M. Sandquist, Jay F. Kunze, and Vern C. Rogers and their collegues in Utah show (1997) inconsistencies with the LNT: in comparing EPA lung cancer projections with actual cancer incidence data published by the American Cancer Society, using the US EPA study of radon potential, the EPA Region with the highest background radon levels (CO, MT, ND, SD, UT, WY) exhibits a mean lung cancer incidence rate of 4.4x10-4, which is only 14% of the rate from the LNT model. On the other hand, the EPA Region with the lowest background radon (ID OR WA) exhibits a mean lung cancer rate of 7.3x10-4, which is 390% of the LNT model predicted rate. It is significant that not only are the LNT-projected health effects at considerable variance with actual health data, but that the LNT projections for all EPA Regions consistently scale inversely with actual observations. Dr. W. Schuttmann formerly of the Faculty of
Industrial Hygene, Department of Health, Berlin Germany and Professor Dr. K. Becker of the
German Standards Institute report (1998) that: female lung cancer rates in high
radon uranium mining areas of Southern Saxony are substantially lower than the average of
East Germany. Thus, the data from various countries showing biopositive effects of
increased radon levels can be confirmed in an area which has been closely associated with
the history of radiation health effects. The comprehensive GDR cancer register shows no
increased female lung cancer in this region. In fact, one of the high radon mining
districts was among the lowest of the country. Nevertheless, extreme remediation efforts
have a radon-related cost of about $US 2,000 million. This area is another ideal location
to test the 'official' assumptions about radiation health hazards in general and indoor
radon hazards in particular. The actual risk, comparing the country average and actual
female lung cancers in the high-radon areas between 1983 and 1987, show exactly the
contrary. |
