X-rays ( X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 [ 1] and named it X-radiation to signify an unknown type of radiation.
A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer ...
The dosage of X-ray radiation received by a dental patient is typically small (around 0.150 mSv for a full mouth series [1]), equivalent to a few days' worth of background environmental radiation exposure, or similar to the dose received during a cross-country airplane flight (concentrated into one short burst aimed at a small area). Incidental ...
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
Alabama’s attorney general said Monday that another nitrogen gas execution will go forward in September after the state reached a settlement agreement with the inmate slated to be the second ...
They're second at +190 odds (bet $100 to win $190), and the Bills are ahead of them at +165. The Jets' Super Bowl odds of 22-to-1 rank 11th among NFL teams. Rodgers is the favorite for one award ...
An X-ray tube is a vacuum tube that converts electrical input power into X-rays. [ 1] The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is ...
