This portable, standard counter is perfect for monitoring radioactive sources in the lab. With its power-conserving push button, it detects beta, gamma, and X-radiation (0-10mR/hour)-with easy, one-touch operation. The LED indicator glows and the counter makes clicking sounds as radiation is detected. If radiation exceeds 20mR/hour, the meter indicates the danger by beeping. The unit features a sensitive, accurate Geiger-Müller detector; a unique logarithmic-scale analog meter; and durable construction. Factory calibrated to NIMS (Cesium 137 gamma source). Includes instructions and a 9V battery.
