Web228 Th is generated when 226 Ra, a radioactive isotope that is found in nature, is exposed to neutron irradiation in a nuclear reactor. After the 228 Th is extracted from the material, it is a radioactive source which continuously generates 212 Pb through radioactive decay. 212 Pb can be generated by: - Extracting it directly from the 228 Th, or WebSep 23, 2024 · Alpha (α) decay involves the release of helium ions from the nucleus of an atom. This ion consists of two protons and two neutrons and has a 2 + charge. Release of an α -particle produces a new atom that has an atomic number two less than the original atom and an atomic weight that is four less.

Thallium is malleable and sectile enough to be cut with a knife at room temperature. It has a metallic luster that, when exposed to air, quickly tarnishes to a bluish-gray tinge, resembling lead. It may be preserved by immersion in oil. A heavy layer of oxide builds up on thallium if left in air. See more Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists See more Thallium (Greek θαλλός, thallos, meaning "a green shoot or twig") was discovered by William Crookes and Claude Auguste Lamy, working independently, both using flame spectroscopy (Crookes was first to publish his findings, on March 30, 1861).
