The CsI (Tl) crystal used in Radiation Alert® Probes has a higher atomic number, is more rugged, and less hygroscopic than a typical Nal detector.

The improved gamma ray absorption allows a thinner crystal to be used, effectively reducing the



Type-CsI (Tl) crystal (Cesium Iodide Thallium)

RAP47 RAP640
Thin-crystal (1 mm) optimizes sensitivity to low energy gamma radiation while minimizing sensitivity to higher energies. An excellent detector for Iodine-125 and suitable for thyroid uptake measurements Superior to a 1 x 1-inch NaI detector, this is a great choice for an all-around gamma and x-ray detector. Optimal energy range of about 20 keV to 2 MeV. Highest efficiency for a broad spectrum of gamma-emitting isotopes.
