Taking The Radon Cure

"An internationally respected radon researcher has uncovered some surprising and perplexing evidence. High levels of radon exposure are known to cause lung cancer. Studies of people exposed to such levels in mines demonstrate that conclusively. Then it follows, most peo-ple have thought, that the best level is zero, and any increase should produce an increasing rate of lung cancer. But controversial studies show that this may not be so.

"In one study Dr. Bernard Cohen of the University of Pittsburgh compared average lung-cancer rates in many counties with the average radon rates found in the respective counties. It's an ambitious study - 39,000 measurements in 415 counties.

"The results: In counties where lung cancer in women would have been expected to be up 25 percent from the radon levels, the incidences of cancer were actually down 30 percent. There are others. Finland has average indoor-radon levels of 2.5 picocuries per liter - 2.5 times higher than the world average. Yet the female lung-cancer rate in Finland is only 70 percent that of other industrialized countries."

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
