Longevity

 

Professor Emeritus Myron Pollycove, MD, of Laboratory Medicine and Radiology, UCSF, also reports (1994) that:

"The (reported) decreased mortality risk reported by the US-Japan Radiation Effects Research Foundation (RERF) study of Hiroshima and Nagasaki (Shimizu 1992) is also consistent with the recent article on Nagasaki survivors from Nagasaki University and the Atomic Energy Research Institute, Kinki University, Japan. Mine et al. report (1990) upon the ‘apparently beneficial effect of low to intermediate doses of A-bomb radiation on human lifespan’.

Pollycove 94 Table 11.2

"The decreased RR of non-cancer male deaths to 0.65 (p<0.05) in the 0.50-0.99Gy dose range was to a large extent offset by the RR increase to 1.56 in cancer deaths. The male RR for total deaths in this dose range was 0.88, with low statistical power (p=0.34). Fitting of a U-shaped dose-response relationship confirmed the significantly lower male RR for non-cancerous diseases with maximum reduction to 0.76 (p<0.02) in the 1.00 to 1.49, average 1.08, Gy dose range. Female survivors, on the other hand, showed no significant change in RR of death from all causes until the 2.00 to 5.99 Gy dose range was reached, in which there was a rise of the RR of both cancer deaths (p < 0.0 1) and total deaths."
