Typical background radiation levels for most of the USA are in the 5 to 28 uR/hr range. Readings can be higher for brief periods of time due to normal variations in radiation levels. They can also be consistently higher for areas at high elevations such as Colorado, or with larger natural deposits of uranium, thorium, radon, etc. Radiation Detector - Sper Scientific Calibration Radiation: Gamma - Cesium 137 1 mR/hr = 10 µS/hr Range: 0 to 10mR/hr Typical Accuracy: ±20% Max/Min Detection Energy: 30 KeV to 1.5 MeV Radiation Basics www.hps.org Using a survey meter www.mcgill.ca UNITS OF RADIATION MEASUREMENT www.antirad.com Nuclear Radiation Detection Summary www.vaughns-1-pagers.com National Radiation Map www.radiationnetwork.com Online Geiger Counter Nuclear Radiation Detector Map www.blackcatsystems.com www.iris.edu www.ustream.tv
