The UK Government has heightened security at its seaports to detect the illegal import of materials that could be used in a radiological dirty bomb.

The installation of radiation detectors is one way the British Government has improved its safeguards against terrorism, according to the Under Secretary of State for Security and Counter-terrorism Alan West.

“We have looked much more closely at chemical, biological, radiological and nuclear materials which could be used to make dirty bombs and how we can stop them being brought it,” West said.

The portals enable authorities to detect any kind of explosive on board a ship when a container comes through the port, the government said in a statement.
