Thorium | Th - PubChem

Thorium is a natural radioactive chemical element with the symbol Th and atomic number 90. In nature, virtually all thorium is found as thorium-232, and it decays by emitting an alpha particle, and has a half-life of about 14. 05 billion years (other, trace-level isotopes of thorium are short-lived intermediates of decay chains). It is estimated to be about four times more abundant than ...

Journal Archive - Johnson Matthey Technology Review

In contrast, small additions of elements such as thorium and cerium have been shown to segregate to grain boundaries and to improve ductility (2, 25). The very coarse grain structure of Ir and Ir alloys in cast ingot form makes the material particularly sensitive to cracking at relatively small tensile strains.

Nickel - Wikipedia

Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge.

3. What are the levels of exposure to arsenic? - GreenFacts

Arsenic concentrations in air range from very low (0.02 to 4 ng/m3) in remote and rural areas, to low (3 to about 200 ng/m3) in urban areas. Much higher concentrations (more than 1000 ng/m3) can be found near some industrial sources such as smelters, although in some countries, very high levels are no longer found because of measures taken to reduce pollution.
