POSC Units Classes POSC 2005-04-25 2006-05-25T09:10:05-0500 John Bobbitt This file documents the placement of POSC units of measure into quantity classes. To the best of our knowledge, this placement is accurate, and reflects work done by POSC and others in the creation of these classes and their units of measure. However, POSC makes no guarantee of the accuracy or completeness of this classification. Users are free to use these classes at their own risk with the understanding that POSC is not liable for any use or misuse of these classes. POSC This file was created to aid developers in the development of restricted lists of uom symbols, based on their usage of broadly defined quantity classes. Note that the uom symbols are based on the CatalogSymbol element of POSC units dictionary (version 2.2) found at http://www.posc.org/refs/poscUnits22.xml absorbed dose Gy Gy The amount of energy absorbed per mass. Gy mGy rd acceleration linear m/s2 m/s2 Gal cm/s2 ft/s2 gn m/s2 mGal mgn activity (of radioactivity) Bq Bq A measure of the radiation being emitted.
