I don’t know how those scanners work, but I’ve always presumed they’re looking for individual chemicals. There’s not many you’d need to detect to find explosives (probably just high concentrations of carbon, nitrogen and metals?)
- lukan 2y agoThere are lots of different explosives. High concentrations of nitrogen you can also find in the air for example. And metal all around in an airport. Carbon as well.
- AmericanChopper 2y agoThere’s not a lot of solid state nitrogen or metallic powders in an airport. The rest of the high explosives that I’m aware of are all rather dense organics. Possessing those things is how you get yourself selected for secondary screening. Again, I’m not an expert in how these things work, so I’m happy to be corrected. That to me just seems like the most obvious way the new dual energy scanners would be put to use.
