A dirty bomb or RDD (Radiological Dispersal Device) is usually a conventional bomb or improvised explosive device which contains radioactive material. The bomb is used to spread radiation across as wide an area as possible. The bomb is not a nuclear weapon and usually has minimal destructive power, its main purpose being to create a large enough blast to disperse the radioactive material. This material is usually nuclear waste from power stations. Materials most likely to be used in dirty bombs are Caesium-137, Strontium-90 and Americium-241. The actual damage that a dirty bomb could inflict is still the subject of a great deal of contradictory debate.
GammaTect Plus provides sophisticated radiation detection and identification for preventing the storage and movement of materials for dirty bombs combined with alert system and camera triggers.
Identifinder radiation detection units are able to distinguish between sources of a threatening nature from trace radiation in normal products of a non-threatening nature.
