Handheld Radiation Meter - Geiger Counter 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 Meter registers 0~100mR/hour (milli-Roentgen) and 0~1000 uSv/hour (micro Sieverts) 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. If required, this unit can be calibrated to NRC standards by a government authorized test facility. Used in applications where radiation may be present in greater than trace amounts. Visit the US EPA website for information on the health effects of radiation exposure. Dimensions: 6.75" × 3.25" × 1½" (171 × 83 × 34 mm) Weight: 1 lb (454 g.
