ok...back to war, tuesday, 19.39 pm...just a tip...this is the honeycomb carbon nested material...1. bcz its nested, on a format of hexangal, the reader will hv lots of difficulty on determine the colour based contrast for detection, on the other hand this made with carbon...not only carbon is present on about everything degradable and so, its not a chemical base for the detectors, but also, present on explosives...this is all for any pyrogen...not for nuclear.
