X-ray Absorption Spectroscopy X-ray absorption spectroscopy (XAS) techniques probe short- and medium-range order‚ yielding information on bond lengths‚ coordination numbers‚ local coordination geometry and the oxidation state of atoms for a wide range of solid and liquid systems. XAS experiments require an intense‚ tunable photon source only available at synchrotrons. Features • medium and high energy (from atomic number Z=20 upwards) XAS‚ XANES (x-ray absorption near-edge structure)

Gamma Rays in Radiotherapy 8B Lae Eun Kim In this unit‚ we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use

In this article "Airport Screeners Could See X-rated X-ray’s" Joe Sharkey tells us a little bit about a new airline security program. Sharkey advertizes that airlines are trying to bring in X-ray units that will be able to look beyond clothing‚ to the outline of bare skin. This precaution is becoming effective because technology is getting more advanced. Since metal detectors can’t be as reliable as we once thought‚ serious measures need to be demanded. However‚ scientists have discovered the previous
