NT6101-N50 environmental grade chi and gamma dose rate meter

Product Introduction

The X and gamma radiation air specific release energy (absorbed dose) rate meter for environmental monitoring uses large-sized NaI (Tl) scintillation crystals as detectors, mainly used for measuring the X and gamma radiation air absorbed dose rates in low radiation environments, searching for radiation sources, etc. Applicable to environmental protection departments, disease control centers, geology and mining, medical and health, nuclear power plants, public safety and nuclear emergency, national security, military customs and entry-exit inspection and quarantine, civil aviation, railways, highways and shipping, nuclear decommissioning and decontamination departments.
