フィルタータイプGlass fiber GF10, grade H12 for prevention of contamination and pollution of the iodine cartridge by aerosols
Air intake flange: DN 16; KF
Air intake filter diameter: 50 mm; S grade
Filter cartridge diameter: 58 mm; charcoal
Cartridge service life: several weeks depending on the iodine conc. of the ambient air
Cartridge activity load: 1 MBq
入力6 counters in total
4 counters are used for the three energy windows: Background energy window left; iodine energy window; background energy window right
製品タイプIodine Monitor
測定範囲Min. 100; Max. 105 Bq/m3 related to 60 minutes sampling time
Measuring Principle: The sample air is passed through a 2 ¼ “ standard filter cartridge filled with iodine adsorbent. Elementary as well as organically bound iodine are precipitated. The filter cartridge is manually exchanged. A NaI scintillation detector located in the axis of the filter cartridge continuously measures the low-energy gamma quanta emitted by the accumulated I-125 activity. The pulse height is discriminated by an appropriately set iodine window.
