Research summary

The Nuclear Emergency Response group of Natural Resources Canada provides emergency response mapping of radioactive contamination, and assists in security operations searching for radioactive threat material.  In support of this responsibility, we conduct research and development of instruments and techniques for the detection and characterization of sources of radioactivity.

Students are sought for active research areas including:

* Design and testing of an unmanned-aerial-vehicle-mounted neutron detector and directional gamma-ray spectrometer

* Imaging methods applied to gridded data obtained during either manned or unmanned aerial vehicle flight

* Deployment and testing of a fieldable Compton gamma imager for long-range characterization of multiple and distributed sources of radioactivity.
