Infrared, motion detectors, i-i's and sound filters couldn't detect anyone else in the bunker.
The detector detects how much light was reflected from or transmitted through the sample.
However, as mentioned in the opening remarks, the ideal detector should detect region invariant up to viewpoint change.
The detector can detect both charged current and neutral current interactions.
Most explosive detectors in the market today can detect both vapors and particles of explosives.
Sensitivity is defined as the lowest amount of explosive matter a detector can detect reliably.
The infrared detector would then detect a difference in temperature, which would translate to moisture.
These detectors are extremely sensitive and can detect minute amounts of radioactive materials.
I'm quite happy to believe the detector detects what it claims to detect.
Joe told me that you'd calculated what the detector should have detected, and sure enough it did.
