BetaScint appears to have gone out of business in 2005. The BetaScintTM fiber-optic sensor was a rapid less-costly alternative for measuring Sr-90 or U-238 contamination in soil samples on site. The BetaScintTM sensor contained plastic fibers doped with fluorescent compounds. These one-millimeter-thick fibers lit up (i.e., scintillate) when they contacted highly energized beta particles produced by radionuclides. The intensity of the light was counted by photo-detectors to determine the beta radioactivity of the soil sample. When background counts were subtracted, the number of scintillations counted in a given time was proportional to the average beta radioactivity of the soil sample.

The BetaScint(TM) sensor is designed to measure beta emissions from Sr-90 and U-238 in soils. The sensor is 150x35x8cm; it can measure contamination of the soil surface or of a soil sample spread over More Information
