Model 375P-336 Series

The Model 375P-336 Series are monitoring systems that consist of a Model 375P digital controller coupled with two lead shielded 2753 cm³ (168 in³) plastic scintillation detectors. The Model 375P-336 is designed for indoor applications, while the Model 375P-336‑1L has detectors housed in waterproof enclosures that can be mounted outdoors. The Model 375P controller is not weatherproof and must be mounted either indoors or within an environmental enclosure (available separately).

These simple and cost-effective solutions offer a system that is easy to operate and maintain. The controller supplies local alarms but can also be connected to external alarms or put onto an Ethernet network if desired. Each system has a 24-hour battery backup to keep it operational in the event power is lost.

Medical Application

The Model 375P-336 Series are ideal for monitoring personnel or laundry for possible contamination in a nuclear medicine department. The monitor may also be used as a radiation contamination triage device to alert emergency department personnel of potentially contaminated patients or equipment coming into the emergency room. In environments where equipment, carts, or other traffic may strike and damage the detectors, Ludlum Measurements encourages the use of an optional protective rail (PN 2311167).

Surface Contamination Inspection

Inspecting items using handheld instruments can be too time consuming in many cases. The Model 375P-336 Series facilitate more rapid and uniform inspections by placing two relatively large scintillation detectors in close proximity to incoming or outgoing articles undergoing inspection. Both detectors are continuously monitored by the digital controller so any contaminated 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.

Also Available

Model 375P-336V & Model 375P-336-1LV: These versions include IR sensors that prevent the unit from alarming unless something is passing between the detectors and the alarm threshold has been exceeded.
