Small and light enough to go anywhere, yet sensitive enough to detect minuscule amounts of gamma, beta or X-rays. Excellent for scanning lab work areas and clothing for traces of radioactivity after clean-up, or as a personal monitor in areas of potential radiation exposure. Useful in school labs for geology and science projects. Uses a Geiger-Mueller tube detector. The Meter registers 0~10mR/hour (milli-Roentgen) and 0~100?Sv/hour (microsieverts) on a dual scale. Audible clicking will increase with the amount of background radiation. *Beeping begins at 20mR/hr, increasing in frequency in proportion to the radiation level. Powered by a 9-Volt battery, included, which lasts 50 hours at normal background levels.
* Dimensions: 168 x 83 x 35mm. Weight: 241g.
