Purpose:
measurement of alpha and beta aerosol volumetric activity in air of rooms and ventilation system at NPPs, radiochemical plants and other radiation hazardous sites. 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 volumetric activity indication
• On-line spectrometry
• Up to 6 months filter cassette autonomy
• Can be used as temporary bypass for ABPM 201S or ABPM 201L when fixed unit is in maintenance with no loss of monitoring capability

APPLICATIONS

• Radioprotection of workers
• Operational process monitoring
