Tipo de productoIodine Monitor
Intervalo de mediciónMin. 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.
