The strontium unit is a Physical unit unit used to measure the amount of radioactivity from strontium 90, a radionuclide found in nuclear fallout , in a subject s body as the human body absorbs strontium as if it were calcium , incorporating it into the skeleton , its presence is very common. One strontium unit is equal to one pico curie from strontium 90 per gram of calcium 37 becquerel s per kilogram in the subject s skeleton. The United States National Academy of Sciences holds that the maximum safe measure of strontium 90 in a person is one hundred strontium units 3700 Bq kg . The average United States American is estimated to have three to four strontium units. The strontium unit was formerly known briefly as the sunshine unit , a term promoted by the United States Department of Defense until public ridicule brought about its disuse. Among the sources of this outcry was a George Carlin performance, released on the CD Parental Advisory Explicit Lyrics , during a passage on governmental euphemisms for dangerous or unethical activities The Pentagon has actually begun measuring nuclear radiation in something they call sunshine units References Unreferenced date March 2007 See also Project GABRIEL Project SUNSHINE Category Units of radiation dose Category Strontium ... more details

The alkaline earth metal strontium Sr has four stable, naturally occurring isotope s sup 84 sup Sr 0.56 , sup 86 sup Sr 9.86 , sup 87 sup Sr 7.0 and sup 88 sup Sr 82.58 . It has a standard atomic mass of 87.62 1 unified atomic mass unit u . Only sup 87 sup Sr is radiogenic it is produced by decay from the radioactive alkali metal sup 87 sup rubidium Rb , which has a half life of 4.88 10 sup 10 sup years. Thus, there are two sources of sup 87 sup Sr in any material that formed during primordial nucleo synthesis along with sup 84 sup Sr, sup 86 sup Sr and sup 88 sup Sr, as well as that formed by radioactive decay of sup 87 sup Rb. The ratio sup 87 sup Sr sup 86 sup Sr is the parameter typically reported in geology geologic investigations ratios in minerals and Rock geology rock s have values ranging from about 0.7 to greater than 4.0. Because strontium has an electron configuration similar to that of calcium , it readily substitutes for Ca in mineral s. s Twenty nine s Thirty one unstable isotopes are known to exist, the longest lived of which are sup 90 sup Sr with a half life of 28.9 years and sup 85 sup Sr with a half life of 64.853 days. Of importance are strontium 89 sup 89 sup Sr with a half life of 50.57 days, and strontium 90 strontium 90 sup 90 sup Sr .

Orphan date January 2011 Lanthanum strontium cobalt ferrite LSCF , also called lanthanum strontium cobaltite ferrite is a ceramic material of the ferrite magnet ferrite group. It is a mixture of lanthanum III oxide , strontium oxide , cobalt oxide and iron oxide cobalt iron oxide . It is black in color and crystallizes in a skewed perovskite structure. LSCF undergoes phase transformations at various temperatures depending on the composition. This material is considered a mixed ionic electronic conductor with transference number close to 1. It can become non stoichiometric at low oxygen partial pressures and high temperature. LSCF is being investigated as a material for intermediate temperature solid oxide fuel cell cathode s, LSCF is also investigated as a Membrane selective barrier membrane material for separation of oxygen from air, for use in e.g. cleaner burning power plants. http www.sciencedaily.com releases 2007 08 070802201909.htm It is commercially available.
