Abstract:
A nuclear barcode has been proposed to identify taggants added to explosives, which encodes identifying information by adding a unique combination of taggant elements at different concentration levels. Testing was conducted on two single element solutions at three concentrations to determine minimum detection concentration levels. The effect of delaying the time to obtain measurements and its effect on uncertainty over approximately four half-lives (5 days) was tested on five 1 part per million holmium solutions.
