What is XRAY hardness?
The penetrating capacity of x-rays that is an inverse function of the wavelength.
What is radiation hardness assurance?
What is RHA? • RHA consists of all activities undertaken to ensure that the electronics and materials of a space system perform to their design specifications after exposure to the space radiation environment.
What is intensity in radiography?
Intensity – the rate of flow of electromagnetic radiation energy through unit area perpendicular to the direction of motion of the wave.
What are the properties of Xray radiation?
The X-Rays properties are given below:
- They have a shorter wavelength of the electromagnetic spectrum.
- Requires high voltage to produce X-Rays.
- They are used to capture the human skeleton defects.
- They travel in a straight line and do not carry an electric charge with them.
- They are capable of travelling in a vacuum.
What does the term Bremsstrahlung mean?
braking radiation
bremsstrahlung, (German: “braking radiation”), electromagnetic radiation produced by a sudden slowing down or deflection of charged particles (especially electrons) passing through matter in the vicinity of the strong electric fields of atomic nuclei.
What is radiographic technique?
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography (“diagnostic” and “therapeutic”) and industrial radiography.
What is called bremsstrahlung?
bremsstrahlung, (German: “braking radiation”), electromagnetic radiation produced by a sudden slowing down or deflection of charged particles (especially electrons) passing through matter in the vicinity of the strong electric fields of atomic nuclei.
How is the hardness of a material measured against the scale?
The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For example, if some material is scratched by topaz but not by quartz, its hardness on the Mohs scale would fall between 7 and 8.
What does hardness mean in radiography?
hardness (of radiographs), n a term used to indicate in a general way the quality of x-radiation, with hardness being a function of the wavelength; the shorter the wavelength, the harder the x-radiation.
What does hardness mean?
hard·ness 1 The degree of firmness of a solid, as determined by its resistance to deformation, scratching, or abrasion.#N#See also:… 2 The relative penetrating power of a beam of x-rays, used both within the diagnostic range of energy and in radiation… More
What is the importance of hardness in engineering?
Hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness. Scratch hardness. Scratch hardness is the measure of how resistant a sample is to permanent plastic deformation due to friction from a sharp object.
