WebThorium would make uranium-232 in reactors when being irradiated, which emits dangerous levels of gamma rays. [9] The thorium-uraninium cycle produces uranium-232, which decays to Tl-208, which has a 2.6 MeV gamma ray decay mode. This process is therefore require higher ... Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose … Meer weergeven Thorium is a moderately soft, paramagnetic, bright silvery radioactive actinide metal. In the periodic table, it lies to the right of actinium, to the left of protactinium, and below cerium. Pure thorium is very ductile and, as … Meer weergeven A thorium atom has 90 electrons, of which four are valence electrons. Four atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, 7s, and 7p.

WebThorium is poorly absorbed from both the lung and digestive tract, and 70% of the thorium reaching the blood is translocated to the bone, 4% to the liver, and 16% to all other organs and tissues of the body. Thorium accumulates in the liver, spleen, lymph nodes, and bone marrow, leading to long-term exposure with a diversity of cells. how can i clone my hard drive
