Radioactivity and Earth Movements

Earth Radioactivity Measurements with a Deep Ocean Anti-neutrino Observatory

We consider the detector size, location, depth, background, and radio-purity required of a mid-Pacific deep-ocean instrument to accomplish the twin goals of making a definitive measurement of the electron anti-neutrino flux due to uranium and thorium decays from Earth’s mantle and core, and of testing the hypothesis for a natural nuclear reactor at the core of Earth. We take the experience with...

Atmosphere and Earth Physics Environmental Radioactivity Measurements of Some Egyptian Sand Samples

A long list of row materials are brought from the desert and invested in feeding of many industries. The investigation of radionuclides distribution and radiation levels of such materials is important to assess the potential hazard of radiation exposure for those working in such industries. In this work the high-resolution gamma-ray spectroscopic system was used to measure the radionuclides con...

Radioactivity and thyroid cancer.

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic applic...
