NGM 202L

Noble Gas Monitor

The NGM 202L monitor forms part of the RAMSYS

product line. It has been developed to continuously

sample the volumetric activity of noble gas and

tritium in a radioactive ef uent gaseous sample. This

monitor can operate as a stand alone device or in

conjunction with a particulate monitor (ABPM 201),

iodine monitor (IM 201) and with a high range noble

gas monitor (NGM 203) to form a very wide range

monitoring system.

APPLICATIONS

• Ef uent release monitoring

○ Ventilation ducts

○ Stacks, etc.

• Radioprotection of workers

RELATED MONITORS

• NGM 203S: accident range noble gas monitor

• NGM 204L: low range noble gas monitor

• NGM 204S: low range noble gas monitor

FEATURES

● Dynamic gamma radiation compensation

● Compact and reliable

● Minimum periodic maintenance

● Tritium measurement capability
