ABPM 201L
Particulate, Gas & Iodine Monitors
ABPM 201L
Alpha Beta Particulate Monitor
The ABPM 201L monitor forms part of the RAMSYS
product line.
It has been developed to sample air extracted from
ventilation ducts or stacks. A double silicon detector
performs the gamma compensation and a radial n
grid limits the scattering of the alpha particles (static
compensation) which facilitates the compensation of
the radon and thoron solid progenies by the
processing algorithms (dynamic compensation).
Operating costs are minimised by the autonomous
operation through automatic lter advance
management.
FEATURES
● Static and dynamic compensation of the radon and
thoron solid progenies
● Natural and arti cial alpha volumetric activity indication
● On-line spectrometry
● Up to 6 months lter cassette autonomy
APPLICATIONS
• Effl uent release monitoring
○ Stacks, etc.
• Radioprotection of workers
○ Containment atmosphere
○ Control room air, etc.
