Lightweight, battery-powered, Beta Particulate Monitor that can be used as a portable workplace monitor or a portable CAM for emergency-response assessments.

Benefits

Beta particulate in air detection. Real-time alpha peak-shape-fitting for determining beta background compensation for radon significantly reducing false alarms. Performs both fast-responding (Acute) and high sensitivity (Chronic) measurements. Local Acute and Chronic dose, concentration, and flow logging as well as optional alpha spectrum logging. Optional Alpha monitoring of up to two isotopes of interest. Wireless 802.11g RadNet Output Option for remote monitoring. ASCII Protocol Output Option via WiFi or RS-232 connection. MDC is less than 2x10-9 µCi/cc for Cs-137 using a 30 minute chronic analysis time in a 10 µR/h gamma background. Can be plumbed to house vacuum or external pump for higher flow rates and improved sensitivity. Complete instrument including internal pump weighs 8.3 lbs. 8-Hour battery life. American or SI units.
