Timothy J. Jorgensen, Director of the Health Physics and Radiation Protection Graduate Program and Associate Professor of Radiation Medicine, Georgetown University - You might guess that a frequent flyer’s radiation dose is coming from the airport security checkpoints, with their whole-body scanners and baggage x-ray machines, but you’d be wrong. The radiation doses to passengers from these security procedures are trivial. The major source of radiation exposure from air travel comes from the flight itself. Most people do not fly 370,000 miles (equal to 150 flights from Los Angeles to New York) within their lifetimes. So for the average flyer, the increased risk is far less than 0.01 percent.
Scientists for Accurate Radiation Information, SARI, S.A.R.I.: LNT-based radiophobia fuels needless evacuations, results in extraordinary environmental cleanup costs, inspires avoidance of life-saving medical procedures, produces pressure to lower the diagnostic quality of radiation-related medical imaging, and promotes nuclear fear. Studies supporting LNT are not benign; they do not err on the safe side; and they have deadly consequences.
S Kojima - Tokyo U. of Science, M Tsukimoto - Tokyo U. of Science, N Shimura - Ohu U., H Koga - Lead & Co, A Murata - Lead & Co, T Takara - Takara Clinic: There is considerable evidence from experimental studies in animals, as well as from clinical reports, that low-dose radiation hormesis is effective for the treatment of cancer and ulcerative colitis. In this study, we present 3 case reports that support the clinical efficacy of low-dose radiation hormesis in patients with cancer and inflammation diseases
Edward Calabrese, Professor of Toxicology at the University of Massachusetts, Amherst: This paper provides a detailed rebuttal to the letters of Beyea with offered a series of alternative interpretations to those offered in my article in Environmental Research concerning the role of the U.S. National Academy of Sciences Biological Effects of Atomic Radiation (BEAR) I Committee Genetics Panel in the adoption of the linear dose response model for cancer risk assessment.
