ABPM 201S

Alpha Beta Particulate Monitor

The ABPM 201S 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.

APPLICATIONS

• Efﬂ uent release monitoring

○ Stacks, etc.

• Radioprotection of workers

○ Containment atmosphere

○ Control room air, etc.

• Post-accident operations

○ Containment atmosphere

○ Stacks, etc.
