Contamination detection devices are used to detect surface contamination by radioactive materials. Our measuring instruments respond to even the slightest contamination by radioactive substances and are used to check personnel and material before they are allowed to leave the hazardous area. The scintillation detectors installed in GRAETZ contamination detection devices are not filled with a gas and therefore do not need to be purged with a counting gas. GRAETZ contamination detection instruments can measure alpha, beta and gamma contamination simultaneously and selectively. Learn more about our product solutions.
