Ludlum Model 375P-336

Radiation Waste Monitor

The Ludlum 375P-336 Radiation Waste Monitor is the latest solution to hospital radioactive waste management. The plastic scintillation detectors are much more compact and sensitive than the larger, more awkward NaI probes. For outdoor use, the system can be modified to be weather-proof. If desired, the system can be modified to be connected with the facility computer network. The basic system includes the lightweight Model 375 Electronics and two 168 in (2753 cm) Plastic Detectors with 200'(61m) cables. A 10 Ci Check Source is included to for periodic testing. Options include strobe lights, extra alarms, time/date printers, ethernet kit, software, and even cameras. For rugged environments (i.e. loading docks), consider this system with shielded 1"x3" NaI Scintillation detectors: Model 375-30.

Newer models are now available, with full color display, larger detectors, and interactive touchscreen GUI.
