Moisture Protection for Scintillators

Scintillator plates for medical imaging use alkali-halide crystals that degrade under any level of humidity. While protection with parylene is sometimes used, atomic layer deposition offers a superior solution. ALD technology produces a conformal, pinhole-free barrier coating with a much thinner layer that provides much better protection against moisture


ALD Thin Films encapsulation of scintillator plates

Common scintillator materials include Cesium Iodide (CsI) and Sodium Iodide (NaI), which are sensitive to moisture. Competitive product lifetime requires a thin film encapsulation coating.
