Purpose:
continuous measurement of alpha and beta aerosol volumetric activity in air of rooms and ventilation system at NPPs, radiochemical plants and other radiation hazardous sites, where ionizing radiation sources are used. It has been developed to sample air extracted from ventilation ducts or stacks.

• Static and dynamic compensation of the radon and thoron solid progenies
• Gamma dose rate indication
• Natural and artificial alpha volumetic activity indication
• On-line spectrometry
• Up to 6 months filter cassette autonomy 

APPLICATIONS

• Effluent release monitoring
• Radioprotection of workers
