LM 212S
Off-line Gamma Liquid Monitor
The LM 212S from the RAMSYS product line has
been developed to sample liquid from a pipe, a tank
or a pool. A 1¼"x1" NaI scintillation detector face
a liquid sampler inside a 4 π lead shielding for the
gamma emitting isotope monitoring.
A radioactive source
allows compensation of potential drift whenever tem-
perature changes occur.
The spectrometry capability, based on a 1024 chan-
nel spectrum analysis, allows immediate and easy
radio isotope identi cation in case of alarm.
