| In particular, MISTRAL XM Rooms is designed for free air monitoring, whereas MISTRAL XM Stack is used to monitor the air expelled from a chimney or a stack. In both cases, “X” indicates the number of sampling points: up to 8 (Rooms) or 1 (Stack).
The system is composed of:
The APU is the main user interface with the system, and it consists in a panel PC mounted on a wheeled support. | The SDU-XM includes the NaI(Tl) detector with MCA, the system electronics, a lead shielding well, a pump for air sampling with a control flow meter, and an array of electrovalves (if needed). The system also manages the expulsion of the monitored air.
The accessory flow rate meter STACK-DFM can be included in the stack version, to calculate the specific activity of the expelled air volume. The software installed on the PC displays in real time the measurement, controls the system status, and allows to set the operative parameters, such as the alarm thresholds. The user can define specific regions of interest (ROIs) and thus determine the specific activity (Bq/g) of the sampled air. |
MISTRAL XM
AIR ACTIVATION MONITORING SYSTEM
MISTRAL XM is a system designed to sample and monitor the gamma activity concentration resulting from air activation, in Marinelli geometry.
