SARAD EQF3320 Radon Daughter Product Monitor
The EQF 3320 allows measuring the concentration not only of radon and thoron gas but also of their decay products, in relation with the volume of the particles of the aerosol. The instrument samples free and attached decay products as well as the cluster component within the range of 20 to 100 nm. This component appears commonly during combustion processes in the air.
The small aerosol sampling head can be removed from the device and placed in any other part of the room. The fine pored membrane filter of the newly developed sampling head is exchangeable without any tool. The filter has a reinforced membrane fiber and an automatically controlled rotary vane pump that guarantees a constant air flow through the filter. A stainless steel mesh is employed to separate the free decay products. Several tests have shown an excellent reliability of the measurement results.
- Radon and thoron measurements in indoor air, soil air, and water samples
- Correct dose determination of radon or thoron daughter product exposure
- Derivation of location-specific equilibrium factors for dose estimation using radon dosimeters
- Radiological assessment of interiors in clay houses
- Dose-relevant investigations into the size distribution of aerosols as carriers of radon and thoron daughter product activity
