ABPM 203M
Mobile Alpha Beta Particulate Monitor
The ABPM 203M forms part of the RAMSYS product
line.
Its small and light weight extendable sensor allows
this monitor to function locally next to the respiratory
tract of workers. A dual 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 through unattended
operation, by the use of a continuous  lter and the
on-line spectroscopy capability. All these features
make the ABPM 203M an ef cient diversi ed and
cost effective tool.
