Nuclear radiation is a problem that each one needs to pay attention to, because it may bring some serious consequences, such as disease or even cancer. Our nuclear radiation detector can help you to detect nuclear radiation well, so if you need it, come and have a try. Dose Rates Alarm Thresholds Preset: T his device support preset the dose rates and alarm thresholds, the dose equivalent rate mesuring ranges is 0.01~100uSv/h. LCD Display: This tester adopt a large display screen for you to see the detecting data clearly, you can see the detecting data more clearly. This personals geiger counter can detect the X-rays, -rays, -ray and iodine 131 for you, and this product adopt geiger counter sensors. Wide Applications: This tool can be widely applied in radioactive indication for the work personnel in the following fields: nuclear power plant, accelerator, iron steel industry, chemical industry, isotope application, industrial X-y nondestructive flaw detection, Cobalt source treatments and so on. Specifications: Material: ABS Radiation Detection: X, y and hard rays Normal content standard: within 0.5uSv/h Measurement ranges: Dose equivalent rate: 0.01~100Sv/h Alarm threshold: Dose rate: can be arbitrarily selected in increments of 0.05pSv/h within 100.0 Sv/h Working environment: Temperature -10C~ #43;45C Relative humidity: 95%( #43;45C) Power: 2 * AA batteries (NOT INCLUDED) Package size: 140 * 80 * 30mm / 5.5 * 3.1 * 1.2in Package weight: 200g / 7.1ounce Packing list: 1 * Geiger Counter
