Deep-Earth reactor: nuclear fission, helium, and the geomagnetic field.
Geomagnetic field reversals and changes in intensity are understandable from an energy standpoint as natural consequences of intermittent and/or variable nuclear fission chain reactions deep within the Earth. Moreover, deep-Earth production of helium, having (3)He/(4)He ratios within the range observed from deep-mantle sources, is demonstrated to be a consequence of nuclear fission. Numerical s...
متن کاملNuclear Fission without Microtubules—a Return to the Past?
One of the most familiar images in biology, even to high school students taking an introductory course, is that of newly duplicated chromosomes lined up along the center of a cell at the stage of cell division called metaphase. As the cell enters anaphase, microtubules, rod-like filaments that comprise the mitotic spindle, pull the chromosomes away from one another to opposite sides of the cell...
متن کاملDetecting a Nuclear Fission Reactor at the Center of the Earth
A natural nuclear fission reactor with a power output of 3-to 10 Terawatt at the center of the earth has been proposed as the energy source of the earth’s magnetic field. The proposal can be directly tested by a massive liquid scintillation detector that can detect the signature spectrum of antineutrinos from the geo-reactor as well as the direction of the antineutrino source. Such detectors ar...
متن کاملOptimization of the rate of production 99Mo-99mTC through fission in the TRR
Technetium is one of the most important radioisotopes recognized in medicine which is obtained through the decay of molybdenum 99.The half-life of this radioisotope is 6 hours and it is capable of 140 kev gamma ray emission. Due to its short half-life, this radioisotope must be produced at the site of consumption, so that the shortest possible time interval between production and consumption c...
متن کاملA comparison of rat SPECT images obtained using (99m)Tc derived from 99Mo produced by an electron accelerator with that from a reactor.
Recent shortages of molybdenum-99 ((99)Mo) have led to an examination of alternate production methods that could contribute to a more robust supply. An electron accelerator and the photoneutron reaction were used to produce (99)Mo from which technetium-99m ((99m)Tc) is extracted. SPECT images of rat anatomy obtained using the accelerator-produced (99m)Tc with those obtained using (99m)Tc from a...
