NGM 216S

Particulate, Gas & Iodine Monitors

NGM 216 S

Low Range Beta Noble Gas Monitor

The NGM 216S monitor from the RAMSYS product

line has been developed to continuously measure

beta volumetric activity of radioactive gaseous

sample. The sample is drawn from discharge stacks,

reactor building, ventilation ducts or working areas

via a pumping system. This monitor can operate as a

stand alone device or in conjunction with a particulate

monitor (PM 205 or ABPM 201), an iodine monitor (IM

201) or a shielded particulate and iodine sampler (PIS

203) and with a high range noble gas monitor (NGM

203) to form a very wide range monitoring system.

FEATURES

● Compact and reliable

● Calculation of the total released activity through a stack

 ow rate signal provided

● 1E quali cation and embedded safety related software

● Available under 10 CFR 50 App. B, IEC 61226 and

ASME NQA-1 programs for safety related application
