ABPM 201M

Particulate, Gas & Iodine Monitors

ABPM 201M

Mobile Alpha Beta Particulate Monitor

The ABPM 201M 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

● Gamma dose rate indication

● Natural and arti cial alpha volumetric activity indication

● On-line spectrometry

● Up to 6 months  lter cassette autonomy

● Can be used as temporary bypass for ABPM 201S or

ABPM 201L when  xed unit is in maintenance with no

loss of monitoring capability

APPLICATIONS

• Radioprotection of workers

○ Containment atmosphere

○ Control room air, etc.

• Operational process monitoring
