The system is based on the well-known Model 375P-1000 from Ludlum.
The Model 375P-1000 is a digital Model 375 Controller coupled to two shielded 7866 cm3 plastic scintillator detectors. The detectors are encased in weathertight enclosures suitable for the outdoor environment. The Model 375 Controller has been mounted within an environmental enclosure . This cost-effective solution offers a simple system that is easy to operate and maintain.
The system continuously monitors background levels and will alert the user when the infrared sensors detect a contaminated object. Once the object is removed, the system will return to normal (background) monitoring.
The controller supplies local alarms, but can also be connected to external alarms or even put onto an Ethernet network if desired. In addition, a 24-hour battery backup keeps the system operational in the event power is lost.
This system is ideal for inspecting outgoing trash and/or medical waste for possible low-level radioisotope contamination. It will easily pay for itself in the prevention of just one contaminated shipment. Fines assessed by the various regulatory agencies may be significantly more than the cost of installing this monitor at your facility.
Surface Contamination Inspection
Inspecting items using hand-held instruments can be too time-consuming in many cases. The Model 375P-1000 facilitates a more rapid and uniform inspection by placing two relatively large scintillation detectors in proximity to the incoming or outgoing articles under inspection. Both detectors are continuously monitored by the digital controller so any offending item can immediately trigger an alarm. Alarm conditions can be set up to automatically halt production conveyance devices, notify the central office, and even alert key personnel to initiate an immediate response.
