PM-10, Low Energy Scintillation Detector for Gamma Radiation

The PM-10 is a scintillation detector with high sensitivity for the detection of low energy gamma and X-ray radiation.
It is an external probe for a ROTEM radiation meter RAM DA-3-2000
It can be optimized for the detection of I-125 and other low-energy gamma emitters (option).
The high efficiency of the PM-10 provides a minimum detectable level (MDL) of 0.35Bq/cm2 (approximately 1.10-5 µCi/cm2 surface contamination of 125I.

The PM-10 can be connected to the RAM DA-3-2000 portable survey meter as a highly sensitive effluent detector.

The PM-10 contains a highly efficient, hermetically sealed, NaI(Tl) scintillator, 2" diameter and 0.04" thick, coupled to a 2" photomultiplier tube 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.
