Scintillation Probe - 1.0'' x 0.25'' NaI (Tl) crystal (1.0" diam x 0.25 thick) (25.4 x 6.35mm) by SE International

Typically, crystals are grown to order once we find the right one for your needs. Below are the specifications for the most common detectors that we offer in this variety.

NaI(Tl), or Sodium Iodide, crystal is recommended for nuclide identification in room temperature application. It provides the best energy resolution for gamma rays in this environment and is relatively inexpensive. Sodium Iodide probes are available in a wide variety of sizes.

The CsI (Tl), or Cesium Iodide, 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.

1 Inches X 1 Inches (Typically 1.0" dia x 1.0" thick (25.4 x 25.4mm)
2 inches X 2 Inches (Typically 2.0" dia x 2.0" thick (50.8 x 50.8mm)
Smaller and larger custom sizes available.
Nal(Tl) Standard. Optional Extra: BGO, Cs(Tl) or (Na), TSO. Contact for more info.
