MISTRAL XM

AIR CONTAMINATION MONITORING SYSTEM

The MISTRAL XM monitoring system is designed to sample and monitor the activity concentration in the air, in Marinelli geometry. The MISTRAL XM Rooms version can sample and monitor the air coming from up to 8 rooms; the MISTRAL XM Stack version is used to monitor the air expelled from a chimney or Stack.

In both cases, MISTRAL XM is composed of two main parts:

  • Sampling and detection unit: SDU-XM (the “X” stands for the number of sampling points, from 1 to 8)
  • Acquisition and processing unit: APU

The SDU-XM sampling and detection unit consists in a NaI(Tl) detector with MCA electronics (PNAI-MC), a lead shielding, a pump to sample the air, a flow switch to control the pump functioning, and an array of electro-valves which automatically sample the air from the rooms to be monitored. If required, the system can also manage the expulsion of the monitored air, for example into the Stack.

As an option of the Stack version, a flow rate meter (STACK-DFM) can be installed into the Stack, allowing the system to calculate the activity referred to the expelled air’s volume.

The system performs a spectrometric analysis of the detected radiation, thanks to a multichannel electronics and a software specifically designed for this task.

The MISTRAL XM can be included in a environmental monitoring system (i.e. PITAGORA 5700), thanks an Ethernet connection with the central acquisition unit of the system.

In addition to standard supply, the following options are available upon request:

  • Stack flow rate meter for released activity calculation: STACK-DFM
  • Expulsion of the monitored air
  • LaBr3(Ce3+) scintillator detector instead of NaI(Tl)
