Description
• 3 Scintillation Detectors
➢ PARTICULATE DETECTOR:
• Scintillator-photomultiplier assembly & lead plug and handle on the cable end
• Filter collects 99% or more of particulate matter greater than 0.3 microns from the sample
• Filter is viewed by an RD-60 Beta scintillator
➢ IODINE DETECTOR
• A NaI(Tl) detector photomultiplier assembly & lead plug and handle on the cable end
• Sample passes through replaceable charcoal cartridge which absorbs the Iodine
• Iodine is viewed with the RD-60 NaI(Tl) Gamma detector
• A single channel analyzer amplifier (SCA) such as the RM-80, monitors an adjustable
• (typically 10%) window around the I131 photo peak
➢ NOBLE GAS DETECTOR
• Scintillator-photomultiplier assembly and lead plug and handle on the cable end
• Sample enters the shield & passes through a fixed volume chamber then exits the shield
• Fixed volume is viewed by RD-60 Beta scintillator that senses Beta particles from gaseous isotopes
