Raytheon has won a $20.5m contract to develop an automated nuclear radiation detection system by the US Defence Threat Reduction Agency (DTRA).

The integrated stand-off inspection system (ISIS) is an active interrogation nuclear radiation detection system that will provide a fully integrated and automated inspection system to detect and track the movement of shielded special nuclear material.

Raytheon Integrated Defense Systems Engineering vice-president Michael Del Checcolo said that the need to effectively detect and track the movement of nuclear material increased every day.

“ISIS will enable the US Government to more effectively identify and classify nuclear materials to help prevent their unauthorised entry into the country,” he said.

Work will be carried out by a Raytheon-led team with other partners including Los Alamos National Laboratory, Oak Ridge National Laboratory, Advanced Energy Systems, Bubble Technology Industries and experts from the Massachusetts Institute of Technology.
