÷ RADIATION detection company Kromek had its products put to the test last week as its ‘dirty bomb’ detector was used to protect President Trump during his visit to Brussels for a Nato summit.

The mobile phone-sized D3S device was used by Belgian authorities to search for radiological threats in cargo, vehicles and buildings.

Kromek shares rose this month when it revealed fullyear revenue was up 32pc to £11.8m. Yesterday, shares fell 0.9pc, or 0.25p, to 27p.
