Mobile Iodine Monitor

The IM 201M monitor forms part of the RAMSYS

product line.

It has been developed to continuously measure

the gamma volumetric activity of radioactive iodine

sample, in both molecular and organic forms (methyl

iodine), contained in air drawn from stacks, ventilation

ducts or working areas.

An NaI scintillation detector faces the activated

charcoal cartridge in which radioactive iodine is

trapped. The proximity of the detector and the

cartridge, enclose within a 4 π/5 cm (4 π/2 in) lead

shielding, serves to optimize detection ef ciency. A

radioactive

241

Am source built into the NaI

christal allows compensation of temperature and

aging related drifts. The spectrometry capability,

based on a 1024 channel spectrum analysis, allows

radio iodine isotope localization.

APPLICATIONS

• Ef uent release monitoring

• Radioprotection of workers

○ Containment atmosphere

○ Control room air, etc.

• Operational process monitoring

RELATED MONITORS

• IM 201L: “light” version

• IM 201S: seismically quali ed version

• PING 206S: version with particulate and noble gas

• PIM 206S: version with particulate

FEATURES

● Embedded

241

Am source for energy spectrum

stabilization against temperature changes and aging

● 1024 channels spectrum analysis

● Ef uent trapping of both molecular and organic forms

of iodine

● Can be used as temporary bypass for IM 201S or
