RadBall

RadBall is a novel, passive, radiation detection device which provides 3D visualisation of radiation from areas where effective measurements have not been previously possible.

Advantages of RadBall

• Simple deployment, no electrical or data connections necessary

• Smaller than competing gamma imaging technologies

• Can be combined with visualisation software to create 3D representations of deployment area and radiation detected

• Device responds to total doses of between 20 mGy - 100 Gy

• Sensitive to gamma radiation and tested with Co-60, Cs-137 and Am-241

What is RadBall used for?

RadBall provides 3D visualisation of radiation contamination in areas where it has never before been possible. A small, non-electrical device, RadBall can be deployed into high radiation areas without the risk of damage or contamination to expensive equipment. Its radiation sensitive polymer changes colour when exposed to radiation, providing an accurate 3D radiation map of the subject area.

Developed by the NNL, and evaluated by Savannah River National Laboratory, RadBall is suitable for use in hotcells, glove boxes or other enclosed areas of high radiation and provides an innovative solution to many of the nuclear industry's characterisation challenges. RadBall has been proven to detect Co-60, Cs-137 and Am-241 over the radiation range of 20 mGy - 100 Gy.

The 3D visualisation report identifies the high radiation components in the subject area from which staff can develop effective decommissioning/cleanup strategies away from the operating face.

How it works

About the size of tennis ball, RadBall uses a radiation sensitive polymer material which becomes permanently opaque when exposed to radiation. The degree of opaqueness depends upon the absorbed dose. Scanning the polymer once removed from the radiation allows NNL to create a three dimensional visualisation of the deployment environment and the radiation sources found.
