A rising war on terrorists

Technology for detecting and preventing acts of terrorism is addressed. Attention is directed toward methods for detecting explosives. The one technology, thermal-neutron activation (TNA), that has so far proven that it can quickly and reliably detect specified quantities of explosives within luggage and divert suspect bags without human intervention is described. Promising alternatives to TNA, which is very expensive, are resonance absorption of gamma rays and fast neutron activation.<
