Description of poCAMon
The poCAMon personal online continuous air monitor combines a very compact design with a high flow rate and long battery life. The unit measures long living aerosols as well as short living Radon daughters by alpha spectroscopy and beta counting. In a radon atmosphere, the instrument can be used as Working Level monitor.
The instrument recognises if only natural Uranium aerosols have been collected and adjusts the related dose coefficients automatically. The continuous peak shape adaption results in an accurate natural background compensatione independent on filter exhaustion and particle size.
A bright alpha numeric display and the clear keypad allow the operation even under harsh conditions.
The integrated powerful charger recharges the unit within two hours.
Optical and acoustic alerts will warn the user immediately in case of dangerous situations. For first responders, an optional wireless interface (Net Monitors by ZigBee) allows the officer-in-charge to receive the data online from the action forces. The instrument can be ordered also with a GPS receiver.
Because the unit is based on our DACM platform, the whole functionality of that system is available for the user (communication paths, configuration of measurement cycles, configuration etc.).
Applications:
• for monitoring activity concentrations of airborne radioactive aerosols (LLRD) and measurement the radon/thoron equivalent equilibrium concentration (EECRn & EECTh) and/or the potential alpha energy concentration (PAEC) at workplaces.
• in nuclear facilities
• in the NORM industry
• in mining companies
• in nuclear medicine
Features:
• continuous monitoring of breathing air for airborne long-lived radioactive aerosols (LLRD) and short-lived radon decay products
• assessment and minimization of inhalation hazards for workers
• warning of workers in case of high levels of airborne activity
• spectroscopic separation of the nuclides and the complete compensation of the natural radon background for the LLRD measurement
• battery life of more than 30 hours
