英文原文：

EQF 3220 : Particle size specific Rn/Tn gas & daughters monitor

The EQF?3220 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.

The EQF?3220 is equipped with high-end semiconductor radiation detectors, both in the radon measurement chamber and the detection head for the decay products. This allows a perfect separation of the different decay products of radon, using alpha spectroscopy.

The measurement chamber works following the principle of high voltage collection and has, despite its low volume, an extraordinary sensitivity. This means a decisive advantage when it comes to measuring thoron or small probe volumes. The long-term contamination that appears in other measurement principles by the increasing polonium-210 underground is completely annulated.

There is no cross-sensitivity regarding the ambient radiation. The chamber is immune to humidity changes of the environment.

The quality control is a main issue of any radiation measurement. Therefore the EQF?3220 records a complete alpha spectrum for each measured value.

The EQF?3220 has a big touch-screen, showing the measured values. All measured data are stored in a 2?GB memory card and are available from your PC or laptop through a USB interface. Data transmission and device control can be done by radio modems, as well as via ZigBee adapter (Wi-Fi).

A NaI detector to fix the local gamma dose is an optional feature of the device. The EQF?3220 comes with additional input and output terminals to connect sensors and actuators according to client-specific needs. The data sheet shows some examples.

The instrument comes with a factory calibration certificate. The calibration process for Radon (Rn-222) fulfills the requirements of the DIN ISO EN 17025.
