• Radiation Alert® Scintillation Probes

    Cesium Iodide Thallium probes available at various energy sensitivities.

Scintillation Probe / 1 X 1 CsI (Tl) - Cesium Iodide Thallium

CDV700 Replacement Probe

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 background count rate.
