Airport scanners can detect metallic and non- metallic objects on the body, including drugs and gold, hidden under the clothes and in baggage. Still, most times, they cannot detect the exact material, but provide visual cues about the material of the object, in the form of different colors. Airport scanners are specifically designed to detect ...

by using hyperspectral airborne or satellite sensors and applying suitable analytical and classification algorithms allows effective and progressive solutions for specified tasks. This article deals with the recent issues of selected remote sensing methods for detection, analysis and classification of areas with oil contaminations (or oil seeps).
X-ray fluorescence (XRF) is a non-destructive analytical technique used to determine the chemical composition of materials. Portable XRF technology has been around since the late 1960s, and each generation has offered improved size, speed, performance, and ease of use.Today's portable and handheld XRF analyzers have become the standard for instant …
Secondary Electron Detector The secondary electron detector is used for detecting the secondary electrons emitted from the specimen. Its construction is shown in Fig. 6. A scintillator (fluorescent substance) is coated on the tip of the detector and a high voltage of about 10 kV is applied to it.
Hyperspectral Imaging: A Useful Tool to Locate Gold, Oil and Terrorists. In terms of mineral exploration, hyperspectral imaging is well developed. Hyperspectral imaging can be …
Oil and gas in Ethiopia has a history which is a little over a century old. In 1860, an oil seep was discovered, but it wasn't till the 1920's that inexhaustible seeps of oil were verified. It was generally referred to as oil in the Red Sea coast but was later attributed to specific areas in the Ogaden basin.
Geiger himself was part of the detector: he visually counted flashes of light in the scintillator. 2 Description of Experimental Apparatus Figure 2 is a simplified cross section of the scattering geometry located in the vacuum system. The -particle source is a circular foil of 5mm diameter plated with 241Am, and the detector is a 9mm
