Radsafe List:


I am looking for a company that manufactures a Sr-90 check source to
performance test Eberline RO-20 (RO-2 & RO-2a) ion chambers on each range.
The source is mounted in a plexiglass fixture that keeps the source to
detector geometry reproducible .  There is a round plexiglass piece that
rotates around to cover the source with various attenuation thicknesses,
thereby exposing the ion chamber to different dose rates corresponding to
each scale.  I last purchased this device from a company named "The Source"
around the years 1995 to 1996.  I can not locate this company.  Does anyone
know of a company that manufactures this type of instrument source check
