From the Greek word for hidden, kryptos. Say what? Krypton is pronounced as KRIP-ton. History and Uses: Krypton was discovered on May 30, 1898 by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, while studying liquefied air. Small amounts of liquid krypton remained behind after the more volatile components of liquid air had boiled away. The earth's atmosphere is about 0.0001% krypton. The high cost of obtaining krypton from the air has limited its practical applications. Krypton is used in some types of photographic flashes used in high speed photography. Some fluorescent light bulbs are filled with a mixture of krypton and argon gases. Krypton gas is also combined with other gases to make luminous signs that glow with a greenish-yellow light. In 1960, the length of the meter was defined in terms of the orange-red spectral line of krypton-86, an isotope of krypton. Once thought to be completely inert, krypton is known to form a few compounds. Krypton difluoride (KrF2) is the easiest krypton compound to make and gram amounts of it have been produced. For those that are curious, pictures of krypton gas and krypton plasma can be found in the Questions and Answers section of this site.

People starting getting cancers, dying, and children born deformed. (gee, did anyone know all that goes on behind the scene for all your credit reports and credit card processing?) EPA came to investigate. They didn't know what to test for exactly, so submitted request to U.S. G*v where needed to know what was done, so could test properly. The investigation was closed because the answer that came back was as follows, per the VP at the time: "People dying & illness is not an issue of Nat. S ecurity. Unless it is an issue of Nat. S ecurity, we will not answer this request." If go to sptimes site and search for "equifax cancer" can read some in the archives. Very different what media reported and what actually happened & way more people than reported. |
