Compact personal geiger counter, radiation detector, dosimeter. Improved protection case for outdoor use, protecting from dust and humidity. Geiger counter can be used anywhere e.g. indoors or on objects, metals, top soil, etc. Trusted by radiologists, physics labs, jewelers importing metals, junk yard owners, archeologists and just curious folks looking to detect invisible dangers. Our radiation detectors are currently used by MIT students and volunteers at the Chernobyl Exclusion Zone. This latest geiger counter model provides a non-professional consumer with fast and precise measurements that can be used for localization of high-level radioactive sources. Detects dangerous, ionizing radiation such as Beta, Gamma and X-rays. Does not detect non-ionizing radiation such as electromagnetic waves, radio waves, infrared or visible light. This would not work on microwaves. US-based technical support. One-year replacement warranty.
