The NGM 203S monitor forms part of the RAMSYS™ product line.
It has been developed to sample air in discharge stacks, ventilation ducts or working areas. A flow through ionization chamber is enclosed in a 4 π/5 cm (4 π/2 in) lead shielding.
This monitor is designed to meet the noble gas monitoring requirements set forth by the USA Regulatory Guide 1.97 and it can be used before, during and after an accident. It can operate in conjunction with a shielded particulate and iodine sampler (PIS 203™ sampler) and with a low range noble gas monitor (NGM 204™ monitor) to form a wide range monitoring system.
