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. One-button operation, can be used by untrained personnel. Uses a Geiger-Mueller tube detector. The Meterregisters 0~10mR/hour (milli-Roentgen) and 0~100 uSv/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. Note: Radiation Meter 840026 features a broader dual scale: 0~100mR/hour and 0~1000uSv/hour.

Simple, easy to use, and surprisingly sensitive
»
I am a collector and dealer in crystals and minerals and use this meter to check for general levels of radiation - it is surprisingly sensitive for it's size and price, and very well-built - much more so than others in this price range. If you just need a good, high-quality detector for general use and are not in need of scientific measurements, this is a good choice. When purchased new, mine came with a sample of uranium ore to verify the functionality.
