Parallel Hole Collimators

Collimators are used for gamma camera’s and x-ray devices. They collimate radiation and filter scatter. We can supply collimators for most imaging devices on the market. These collimators can be designed according to the desired resolution and sensitivity.

Our collimators and anti-scatter grids can be used for different applications like Nuclear Medicine, Radiology, Radiotherapy, Homeland Security and Electron Microscopes.

RT-50 Laboratory Gamma Ray Spectrometer

The RT-50 is specifically designed to monitor and detect gamma emitting nuclides in environmental samples, construction materials and many other substances including metals.

Floor standing and easy to operate, the specially designed RT-50 gamma spectrum analyser is an indispensable part of any analytical laboratory. As an integral part of your laboratory analysis the RT-50 will rapidly detect and accurately measure extremely low levels of radioactive contamination.

Model 329-32 Laundry Contamination Monitor

The Ludlum Model 329-32 Laundry Contamination Monitor is intended for automatic monitoring of both alpha and beta-gamma contamination on clothing or other light articles presumed to be free of radioactivity, or within release or reuse limits. A motor-driven steel-mesh conveyor belt carries articles between two gas proportional detector arrays.

RadBump - Radiation-Detecting Speed Bump

The RadBump offers a unique radiation detection system that allows the operator to covertly monitor vehicles for potential radioactive threats.

The rugged sensor assembly detects elevated levels of gamma radiation as the vehicle passes over the speed bump and quickly notifies the operator, allowing the user to identify potential threats and segregate these threats from the main flow of traffic for further investigation.


The RadCompass is a unique instrument, offering a compact, easy-to-use, low cost solution for radioactive source localization. This directional survey meter displays both gamma dose rate and 360º directional information and is an ideal tool for first-responders, military personnel, and industrial radiation surveyors.

Model 44-110-2 Windowless Sample Counter Detector

A windowless gas flow proprtional detector for low-energy alpha and beta sample counting.

Model 54 Small Article Monitor

For automated routine contamination frisking to ensure that items leaving controlled areas are clean. The Model 54A is a smaller version of the Model 54 and incorporates identical field proven algorithms and features.

Model 54A Small Article Monitor

The Model 44-110 is a windowless 100 cm² gas proportional detector for tritium detection

Model 375-336, Monitoring System

  • wall-mounted 168 in3 plastic scintillator detectors
