Further Experiments on the Surplus Gamma-Radiation from Granite
Further Experiments on the Surplus Gamma-Radiation from Granite is a scholarly work, published in 1947 in ''Physical Review''. The main subjects of the publication include uranium-238, uranium, mineralogy, neutron, thorium, radiochemistry, physics, potassium, fission, cosmic radiation, geology, Neutron imaging, materials science, mineral, gamma ray, electromagnetic shielding, Fukushima Daiichi nuclear disaster, radiation, nuclear physics, and radium. In order to find out the origin of this unexpected surplus radiation, new experiments were carried out, using essentially the same technique, but shielding the ionization chambers with lead cylinders about 1 cm thick.
