Selenium 74 Metal (Selenium-74) is a stable (non-radioactive) isotope of Selenium. See below table for ENSDF Citation and Half Life. It is both naturally occurring and produced by fission. Selenium 74 Metal is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Selenium Metal 74 additionally has special application in bioavailability as an essential nutrient. Selenium Metal is also available in ultra high purity and as nanoparticles. For thin film applications it is available as rod, pellets, pieces, granules and sputtering targets and as either an ingot or powder. Selenium Metal 74 isotopic material is generally immediately available. Additional technical, research and safety (MSDS) information is available.
Selenium is a Block P, Group 16, Period 4 element. The electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm.
