SAAM-1

DESCRIPTION: Model SAAM-1 Filter Tape Alpha/Beta-Gamma Air Monitoring System is a line operated continuous duty long period air monitor which automatically integrates over preset period and prints results. It incorporates an alarm as well as hard copy. The electronic system is completely modular. Standard configuration reads gross alpha and gross beta-gamma. Has plug in capacity for one or more channels of specific radiation energies, e.g., Pu-239, U-238, etc.

In practice this system draws air through a section of a filter tape for a sufficient period to achieve the sensitivity desired and measures the activity on the tape after a predetermined elapsed time; usually 20 minutes. The system utilizes a high capacity pump and dwell times in the order of 20 minutes. Sensitivity is achieved in the order of 1% of the most restrictive alpha or beta-gamma airborne contamination standard.

APPLICATION: Model SAAM-1 Monitor is used for monitoring effluent from radioactivity utilizing or producing facilities either directly at the stack or other outlet or at the property boundary. It may be left unattended for period up to 45 days furnishing a complete record of activity for the period. The system alarms if filter roll is used up, which can happen if time limit is exceeded.

OPTIONS:

1. Single Channel Analyzer window(s) specifically for PU-239, and U-238 and/or other nuclides.
2. Clock and calendar to give printed date and time of each reading.
3. Calibration function to allow readout directly in µCi/cc or cps/m³ or other units.
4. Integrate function to average results over a 24 hour, or 100-day interval.
