Remote Air Sampling for Canine Olfaction
From Wikipedia, the free encyclopedia
Remote Air Sampling for Canine Olfaction or RASCO (sometimes RASCargO or -in the UK- REST (Remote Explosives Scent Tracing)[1] is a technology for transport security.
The system allows explosives to be detected in the context of transport facilities, specifically within any closed volume being transported, typically transport containers.[2]
Summary of technique
Samples of air from within a container are remotely collected and presented to a suitably trained 'sniffer dog', which will provide an alert if it senses the presence of target material, e.g. explosives.[2]
