Preventing cross-contamination is an important topic for professionals working with explosives or other illicit materials. Substances like these tend to stick to hands easily contaminating other surfaces during contact. Approaching this theory from a security perspective can be very interesting. Especially for the Delta R technology, that is developed as a non-invasive method to look for trace of illicit substances, such as explosives and narcotics.

People handling or in possession of illicit materials, will very likely have trace on their hands. Due to cross-contamination, trace will spread to other contact surfaces as well. This results in low quantities of substance trace, requiring high-end trace detection solutions. The Delta R Item Scanner is such an instrument, oriented to find these low quantity amounts.
Additionally, the Delta R Item Scanner is also very suitable for screening hand-carried items such as phones, keys, wallets and passports. Making this instrument suitable solution for both aviation and non-aviation purposes such as border control, prisons, ports, theatres, malls, railway stations and other critical infrastructure.
