AMS02 Online-Aerosol Monitoring System
Measuring of radioactive aerosols, especially artificial nuclides

The opportunities of AMS02 Online Aerosol Monitoring System:

The aerosol measuring system uses two consecutive static filters:

• The first for aerosol particles.
• A second planar filter for molecular iodine.

The presence of non-natural radioactivity on one of the filters is detected by alpha, beta and/or gamma measurement. In the case of a warning or alarm signal, a third sampling and measuring unit is activated. The air stream exiting the molecular iodine filter is directed to an additional measuring position to detect organic iodine. The 500 filters are transported to the measuring positions with a manipulator and returned to the magazine after the measuring cycle.

Main applications:

• As a monitoring unit in a network for a large-scale early warning radiation system
• Monitoring of nuclear installations and facilities for the storage and treatment of nuclear waste
• Measuring unit in scientific and development institution
• Municipal control unit, mainly for the immediate control of accident radiation of the nuclear industry

The advantages of the Online Aerosol Monitoring System

Combined alpha, beta and gamma measurement in a single system
By using 4 detectors in a single system, there are 3 on-line measurement positions and a separate additional measurement position with special iodine evaluation filter material (in case of increased concentration) for efficient and reliable detection of artificial nuclides in the air. Radioactive iodine plays a very important role in this regard, as its presence in the air is considered a solid indication of a nuclear incident - and its rapid rate of propagation as a primary indicator.

Well-founded know-how delivers precise results
Unique evaluation algorithms that have been used and refined for more than 20 years, as well as a highly configurable isotope library and the use of a coaxial germanium detector (HPGe - High Purity Germanium), provide accurate results and enable online isotope identification.

Sophisticated measuring technology ultimately makes the difference

• Automatic calibration routine using natural content without additional radioactive sources
• Calibration parameters not only take into account the machine parameters but also the environmental conditions at the place of use
• The generous filter storage allows uninterrupted use of >1 year
• Database with data for each filter (eg date, time of last use, airflow and air volume data)
• A special vacuum pump ensures constant volume, regardless of temperature and filter deterioration. This allows comparable, meaningful results
