- PM-11 sensitive 2″ x 2″ NaI(Tl) scintillation probe
PM-11 is a sensitive scintillation probe for detection of gamma radiation.
A low voltage interface connects the RAM DA 2000 monitor with the probe.The PM-11 contains a highly efficient, hermetically sealed, NaI(Tl) scintillator, 2″ diameter and 2″ thick, coupled to a 2″ photomultiplier tube. This is encased in a rugged, splash proof housing for protection against shock, vibration and humidity. The probe also contains a high voltage power supply, single channel analyzer (SCA), pulse shaper, GM saturation indicator, detector identifier and malfunction detection circuitry. This configuration minimizes noise, improving sensitivity and stability.
