NGM 204 S

Low Range Noble Gas Monitor

The NGM 204S monitor from the RAMSYS product

line has been developed to sample air in discharge

stacks or ventilation ducts. The dual silicon diode

detector integrated in a 4 π/5 cm (4 π/2 in) lead

shielded sample volume guarantees high reliability of

the measurements. The  rst silicon diode detects the

beta/gamma radiation from sample volume and the

gamma ambient radiation (background). The second

one detects gamma radiation from the sample vo-

lume and the gamma ambient radiation. This allows

noble gas beta measurement with dynamic gamma

compensation by the processing algorithm.

APPLICATIONS

• Efﬂ uent release monitoring

○ Stacks, etc.

• Radioprotection of workers

○ Containment atmosphere

○ Control room air, etc.

• Post-accident operations

○ Containment atmosphere

○ Stacks, etc.
