Marvin Herndon www.nuclearplanet.com deep-Earth nuclear fission reactor will produce sufficient helium with precisely the range of ratios as observed from deep-source oceanic lavas. Moreover, the ratio of 3He to 4He increases over the lifetime of the georeactor. The high ratios observed in Icelandic and Hawaiian basalts suggest that the end of the georeactor lifetime is approaching, perhaps within the next 100 to billion years, and presumably soon thereafter the geomagnetic field will begin its final collapse.
