The production of x-radiation
WebbWe also studied the effects of background electron density from previous discharges. We find that X-radiation and γ-radiation are enhanced when the on-axis air density is reduced by more than ∼25%. WebbTo produce a just perceptible increase in receptor exposure, the radiographer should increase the mAs by 30% For the same FOV, spatial resolution will be improved using a …

WebbFor X-rays generated by an X-ray tube, the part of the energy that is transformed into radiation varies from zero up to the maximum energy of the electron when it hits the anode. The maximum energy of the produced X-ray photon is limited by the energy of the incident electron, which is equal to the voltage on the tube times the electron charge, so a 100 kV … WebbX-Ray Production •Radiation-producing devices produce X-rays by accelerating electrons through an electrical voltage potential and stopping them in a target. •Many devices that use a high voltage and a source of electrons produce X-rays as an unwanted byproduct of device operation. These are called incidental X-rays. Production of X-rays
WebbBremsstrahlung is electromagnetic radiation similar to x-radiation. It is emitted by a charged particle as it decelerates in a series of collisions with atomic particles. This mechanism is illustrated in Fig. 1.25, where a beta particle traveling through matter approaches a nucleus and is deflected by it.This deflection causes a deceleration of the … http://www.columbia.edu/itc/hs/dental/sophs/material/production_xrays.pdf
