Assessment of blood levels of heavy metals including lead ...

Exposure to environmental heavy metals is common among African children. Although many of these metals are known neurotoxicants, to date, monitoring of this exposure is limited, even in countries such as Uganda that are undergoing rapid industrialization. An assessment of the burden and potential causes of metal exposure is a critical first step in gauging the public health burden of metal ...

It's Elemental - The Element Cesium

Cesium reacts violently with water and ice, forming cesium hydroxide (CsOH). Cesium hydroxide is the strongest base known and will attack glass. Cesium chloride (CsCl) and cesium nitrate (CsNO 3) are cesium's most common compounds and are primarily used in the production of other chemicals. Estimated Crustal Abundance: 3 milligrams per kilogram

Caesium cadmium chloride - Wikipedia

Caesium cadmium chloride (CsCdCl 3) is a synthetic crystalline material. It belongs to the AMX 3 group (where A=alkali metal, M=bivalent metal, X=halogen ions). It crystallizes in a hexagonal space group P6 3 /mmc with unit cell lengths a = 7.403 Å and c = 18.406 Å, with one cadmium ion having D 3d symmetry and the other having C 3v symmetry.

Caesium-137 - Wikipedia

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products ...
