GENERAL DESCRIPTION:
Model RMDF-60L is a portable lightweight continuous radiation air monitor that measures near real-time gross radioactivity levels on a 47 mm glass fiber filter paper. The system provides audible and visible alarms based upon an operator selectable activity or concentration value. Gross beta-gamma radioactivity is measured as a Cs-137 equivalent value. Other specific isotopes are operator selectable. Metric or English units are available as a factory installed selection. The portable lightweight CAM is ideal for homeland security applications and for commercial nuclear power plant emergency kits. Typical detection sensitivity is 1.4E-9 µCi/cc based on the Cs-137 isotope and sampling for ten minutes. Longer sample collection times result in better detection sensitivity. The typical flowrate range is 30 – 60 LPM depending upon the airflow resistance of the filter media. Typical flow range 30-60 SLPM (1.1-2.1 SCFM).
