This product is a high sensitivity radiation dose alarm device, mainly used to monitor X, γ and β rays. It has features such as high sensitivity and accurate measurement. Widely used in an environment where the existing radiation environment,the human body receives a dose of radiation supervises and protects,such as family decoration, radiation-producing enterprises,hygiene, radiation treatments, nuclear laboratory, nuclear station,control of import and export trade, building materials ,petroleum chemistry, general geological surveys, used continuously,Detection of defects in industry and others. Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. It is made of material, coated with silicone, is non-slip and non-slip, wear-resistant and provides a comfortable grip. It adopts counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation. Configured color LCD screen with multi-functional monitoring pages, real-time display of the current dose power value in real time, cumulative measured value, cumulative saved dose power, maximum value, average value, starting date, cumulative time. The detector is used to measure X, γ and β radiation, is optimal for measuring small changes in radiation levels and has a high sensitivity for the most commonly used nuclides. The design of three alarm modes, with sound/light/vibration alarm, when the dose power and cumulative dose exceed the threshold, and the dose power and cumulative dose thresholds can be set manually. Wide applications, suitable for family decoration, radiation producing enterprises, hygiene, radiation treatments, nuclear laboratory, nuclear station, import-export trade inspection, building materials, petroleum chemistry, general geological surveys, used steels, industrial defect detection and others.
