DOE’s letter of concern about BEIR 7 report

(Jul. 15, 2005) “..between the BEIR 5 Report of 1990 and last year, new and exciting biological research has been published demonstrating that cell in tissues respond very differently to radiation than isolated cells in culture and that cellural responses to low doses of radiation are very different from responses to high doses of radiation.” Continue reading

Nuclear shipyard worker study (1980–1988): a large cohort exposed to low-dose-rate gamma radiation

(June 2, 2005) A summary of the 1991 Final Report of the Nuclear Shipyard Worker Study (NSWS), a very comprehensive study of occupational radiation exposure in the US. The NSWS compared three cohorts: a high-dose cohort of 27,872 nuclear workers, a low dose cohort of 10,348 workers, and a control cohort of 32,510 unexposed shipyard workers. Continue reading

Nuclear shipyard worker study (1980–1988): a large cohort exposed to low-dose-rate gamma radiation

(Jun. 2, 2005) Information from the unpublished 1991 Final Report of the Nuclear Shipyard Worker Study (NSWS). The NSWS is the world’s largest and most thorough study of health effects of low-dose- rate ionising radiation to nuclear workers. Continue reading

Radiation Risk in Perspective

(August 1, 2004) In accordance with current knowledge of radiation health risks, the Health Physics Society recommends against quantitative estimation of health risks below an individual dose of 5 rem1 in one year or a lifetime dose of 10 rem above that received from natural sources. Continue reading

Radiation risk in perspective

(Aug. 1, 2004) In accordance with current knowledge of radiation health risks, the Health Physics Society recommends against quantitative estimation of health risks below an individual dose of 5 rem1 in one year or a lifetime dose of 10 rem above that received from natural sources. Doses from natural background radiation in the United States average about 0.3 rem per year. A dose of 5 rem will be accumulated in the first 17 years of life and about 25 rem in a lifetime of 80 years. Continue reading

Radiation Hormesis: Demonstrated, deconstructed, denied, dismissed, and some implications for public policy

(Aug. 1, 2003) The prevailing view of regulatory agencies and advisory groups is that all radiation is bad for health, and exposure to any form of it should be minimized. While high-dose radiation, regardless of source or intention, is harmful to health, evidence is presented that chronic doses up to 100 times those of normal ambient (including medical) exposures are beneficial, mainly due to lower cancer rates. Further evidence is presented that single, acute doses of up to 50 rad are beneficial, including in treatment of cancer and gangrene. Data are cited to show that below-ambient radiation levels are unhealthful, and that some radiation may be essential for many life-forms. Continue reading

The Hormetic Dose-Response Model Is More Common than The Hormetic Dose-Response Model Is More Common than the Threshold Model in

(September 12, 2002) The threshold dose-response model is widely viewed as the most dominant model in toxicology. The present study was designed to test the validity of the threshold model by assessing the responses of doses below the toxicological NOAEL (no observed adverse effect level) in relationship to the control response (i.e., unexposed group). Continue reading
