New Spectroscope Perfect For Asteroid Mining, Planetary Research
Science_afficionado writes: Scientists at Fisk and Vanderbilt Universities are developing a new generation of gamma-ray spectroscope that is light weight, compact and don't require much power but have the capability for detecting veins of gold, platinum, rare earths and other valuable materials hidden within asteroids, comets, moons and other airless objects floating about the solar system. "A gamma-ray spectroscope records the intensity and wavelengths of the gamma rays coming from a surface. This spectrum can be analyzed to determine the concentration of a number of important, rock-forming elements ... The key to the new instrument is a recently discovered material, europium-doped strontium iodide (SrI2). This is a transparent crystal that can act as an extremely efficient gamma-ray detector. It registers the passage of gamma rays by giving off flashes of light that can be detected and recorded."Read more of this story at Slashdot.
