Mobile Iodine Monitor
방사선 유형:
131I
Inspect for gaseous iodine activity virtually anywhere in the nuclear power plant with the Thermo Scientific™ FHT 1702 Iodine Monitor. Designed for various air contamination monitoring applications as well as for immission and emission measurements, the FHT device monitors gaseous iodine activity from first measurement to present activity concentration. Depending on the measuring application, the total iodine activity can be detected. A second energy window with thresholds above and below the iodine window measures the background count rate (trapezoid method) in parallel to the sampling.
The FHT 1702 Iodine Monitor comes in fixed units and mobile units for easy transport.
- Maintenance-free and low-noise gas ring vacuum pump
- User-friendly, maintenance-free long term operation
- For use in ambient air monitoring networks or stack emissions monitoring systems
- Excellent selectivity against other iodine isotopes or interfering noble gases
- Direct read-out of measured values in physical units of Bq/m3
- Aerosol filter heated air inlet for optimized iodine retention
- Menu-driven calibration procedure with complete track record of efficiency data.

Measuring Principle: Fixed filter monitor for the detection of the 364 keV line of 131I by a NaI detector. Compensation of higher energy gamma lines is realized with the help of online background subtraction by the trapezoid method. A built-in lutetium adapter is used for continuous peak-stabilization.
