We service with OEM quality and the value of an independent service organization. (MCL) of 15 picocuries per liter (pCi/l) for total alpha particle activity, excluding radon and uranium, in drinking water. Americium-241 would be covered under this MCL. For more information about how EPA addresses americium-241 at Superfund sites, please contact either: EPA’s Superfund Hotline 1-800-424-9346 or 1-800-535-0202 Americium-241 emits alpha particles with almost the same energy as 238Pu, the source used in the original Metting design. The foil is comprised of a silver overcoat and undercoat, silver plus 241Am oxide active layer, and 0.006 in thick silver backing that is welded and rolled.

De senaste tweetarna från @malesource Gamma ray spectra of strong 241Am sources may reveal information about the source composition as there may be other radioactive nuclides such as progeny and radioactive impurities present. In this work the possibility to use gamma spectrometry to identify inherent signatures in 241Am sources in order to differentiate sources from each other, is investigated.

2017-03-09 · We're in the optimization phase of our game and we've gotten pointers towards transparency/alpha in textures/sprites being quite costly to render. So I've checked out the 'Alpha Source' setting on our Textures and tried to change it to 'None' from 'Input Texture Alpha'.
