Ludlum Model 44-169-4  Scintillation hand-held pressurized ion chamber thatLudlum Part no. 47 3647 Model 44 169 4 This is a 0. 5in x. 0. 5in x 24in Plastic scintillator in an aluminum housing (as opposed to the usual black plastic and tape) mounted in a PVC case used for portal monitoring. Note the pin connector. There is a standard C connector inside but that one is designed to be waterproof for outside use. These can be paired with Ludlum portal monitor meters, or standard meters if housed indoors. We have meters that can
