德国SARAD氡钍子体测量仪EQF3220

氡钍子体测量仪EQF3220介绍:

在SARAD所有氡钍以及子体测量产品领域内,氡钍子体测量仪EQF3220是**端的一款仪器。 它包含了针对现场氡状况评估,以及科学研究所需要的所有组件。 除了同时氡钍测量以外,还包括了氡钍子体,以及对应不同气溶胶颗粒体积的相关性测量。 仪器除了分别收集结合态与未结合态子体以外,还收集了粒径在5至60纳米范围内的凝聚态粒子。 这部分通常在燃烧过程时出现在空气中。

氡钍子体测量仪EQF3220外置气溶胶采样头可以从主机分离,从而实现室内任意位置的摆放。 独特采样头设计,实现徒手快速更换滤膜。 通过采用增强纤维型滤膜以及对叶片泵的自动控制,使得流量恒定并且可调。 不锈钢丝网用于分离未结合态子体,大量实验数据验证了完美的实验结果与可靠性。

氡钍子体测量仪EQF3220同时在测氡模组与测子体模组上配备了高端半导体放射性探头,通过独有的阿尔法能谱算法, 实现了不同子体的完美辨识分离。

氡钍子体测量仪EQF3220内置高压氡测量腔室,经由特殊设计,实现了小腔室体积与高灵敏度的完美结合,在钍测量与小采样量时表现更为突出。 其他快速氡连续测量法(例如电离室法,闪烁室光电倍增管法)所面临的长效性递增本底210Po污染, 也被完全的剔除,而且不受环境本底影响。 独特腔室对于湿度变化完全不敏感,完全无需干燥桶。

对于每个放射性测量而言, 测量置信度是个中心关键点。 针对这一目的,氡钍子体测量仪EQF3220对每一个测量值,存储其完整的Alpha能谱。由此可以确定每个时间点,其测量的准确无误性。

氡钍子体测量仪EQF3220即时的测量值可由大屏幕触摸屏操作显示。 所有的测量数据存储于1块2GB的存储卡上,通过USB连线PC进行下载读取。 支持连接GSM-GPRS调制解调器或者ZigBee模块进行远程无线的数据传输与仪器控制。 用户还可以选择加装外置碘化钠探测器与EQF 3220相连,用于确定现场Gamma剂量率。 仪器内置更多输入输出端口,用于连接更多用户自定义探测器。

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.
