WHEN HIGH ENERGY ELECTRONS BEAM STRIKE THE METAL TARGET THEY KNOCKED OUT ELECTRON FROM THE INNER SHELL OF THE ATOMS. THESE ELECTRONS ARE CALLED PRIMARY ELECTRONS. AS VACANCY IS CREATED IN INNER SHELL, ELECTRONS FROM THE OUTER SHELL (FROM HIGHER ENERGY STATE ) START JUMPING TO FILL THE VACANCY IN INNER SHELL CREATED. THESE ELECTRON IS CALLED SECONDARY ELECTRONS. WHEN ELECTRONS JUMP FROM HIGHER ENERGY TO LOWER ENERGY STATE THEY EMIT THEIR ENERGY AS A RADIATION. THESE RADIATION IS NOTHING BUT X-RAYS. SINCE X - RAYS IS GENERATED BY SECONDARY ELECTRONS THAT'S WHY IT IS CALLED SECONDARY RADIATION.
Choose the right answers a)What is responsible for the production of x ray emission at the cutoff wavelength? 1)The last emission in a series of many emissions by the incident electron as it loses its energy. 2)The first emission in a series of many emissions by the incident electron as it loses its energy. 3)The most energetic emission in a series of many emissions by the incident electron as it loses its energy. 4)The least energetic emission in a series...
Explain why MRI is safe compared to X-ray scanner using the energy of the electromagnetic radiation.
1 & 2. A is a device placed at x-ray port to absorb low-energy radiation that does not contribute to the diagnostic value of the image and a is a device placed between patient and image receptor to absorb secondary scatter radiation.. 3. Gamma rays have wavelengths that are shorter relative to ultraviolet (UV) rays and would therefore be expected to have Higher or Lower LET values per millimeter of tissue than UV radiation. times greater than 4. In general,...
discuss one type of x-ray radiation at the dentist
Why was the picture called photo 51 in Franklins X-ray diffraction experminet? Who took this picture?
Light of 10 cm wavelength is classified as what type of radiation? x-ray microwave UV γ-ray visible
QUESTION 96 Consider the four X-ray emission spectra shown here. Which was produced at the highest operating KVp? # of X-Ray Photons A 0 10 20 30 40 50 60 70 80 90 100 110 X-Ray Photon Energy (keV)
Radio wave radiation has frequencies from 3.0×105 to 3.0×107 Hz, whereas the frequency region for X-ray radiation is 3.0×1016 to 3.0×1019 Hz. We can say that: 1. The speed of radio wave radiation is X-ray radiation. higher than , lower than or the same as 2. The wavelength of radio wave radiation is X-ray radiation. longer than, lower than, or the same as Please help with both questions .
4 types of electromagnetic radiation: how is x ray interaction different from that seen in other thpes of electromagnetic radiation?
If a certain element being studied by x-ray photoelectron spectroscopy displays an emission spectrum with 6 distinct kinetic energies. What are all of the possible elements that could produce this spectrum?
