Efforts are also being made to deploy similar measures to other cross border vectors including: 1  Pedestrian radiation portal monitoring. 2  Air freight radiation portal monitoring. 3  Crane based radiation portal monitoring. 4  Air luggage radiation portal monitoring. 5  Railway radiation portal monitoring.
