GCA-07W Geiger Counter with Wand - 0.001 mR/hr to 1000 mR/hr Range with Uranium Ore

Images SI Inc's Digital Geiger Counters are the only Geiger Counters in their price range that are accurate enough to be NRC Calibrated and Certified. Useful for detecting and measuring radioactivity. The model GCA-07W uses an external wand that houses the Geiger Mueller tube. Its applications are: Education - Classroom demonstrations and experiments. Emergency Services and Domestic Preparedness; HAZMAT and Compliance Verification. Dirty Bomb Screening and EMT's. It detects the following types of radiation: Alpha above 3 MeV, Beta above 50 KeV, X-Rays above 50 KeV, Gamma above 7 KeV. The Geiger Mueller (GM) Tube detector is Ne + Halogen filled. The GM tube's has a.38 effective diameter 1.5-2.0 mg/cm2 mica end window. The Liquid Crystal Display (LCD) is a 16 character by 2 line that provides an easy to read output. Switch selection allows Geiger Counter to measure and convert radiation (counts per second) into in mR/hr or mSv/hr. Factory calibration ensures accurate measurement. Secondary indicators; audio (clicks) and visual (LED) included. Also includes a headphone jack and a power jack for external power. The GCA-07W outputs serially the counts per second via USB cable to our Windows PC program for charting and recording the measured radiation over time. USB-TTL serial cable is included. Each uranium ore sample is radioactive and measured with A GCA-07W Digital Geiger Counter. Activity of alpha, beta and gamma in Counts Per Minute (CPM) is provided along with measurement certification. Uranium Ore samples typically have one area that is more radioactive than other areas. A measurement of radioactivity is taken from the most radioactive portion of the sample. CPM is total radiation read from the sample. Uranium container size: approximately 1-3/4" height 2-1/2" diameter. 9 Volt battery powered. Battery not included. Images SI Inc., manufacturing electronic instruments and kits for over 25 years.
