WebApr 5, 2024 · X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz). X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons … WebApr 29, 2016 · Radiation: Ionizing radiation. Energy emitted from a source is generally referred to as radiation. Examples include heat or light from the sun, microwaves from an …
WebX-RAYS AND ENERGY X-rays have much higher energy and much shorter wavelengths than ultraviolet light, and scientists usually refer to x-rays in terms of their energy rather than their wavelength. This is partially because x-rays have very small wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a single atom of many … WebProcessing data in space before sending back would reduce unnecessary information， but this can be tricky． Rays in the universe randomly flip the ones and zeroes that computers operate on， introducing unpredictable errors． High levels of radiation can also damage electronic circuits （电子电路）．
WebSep 29, 2024 · The exact amount of radiation exposure in an x-ray procedure varies depending on the part of the body receiving the x-ray. Some examples of common x-ray procedures and approximate exposures are: Single chest x-ray: 0.02 mSv (2 mrem) Dental x-ray (four bitewings): 0.004 mSv (0.4 mrem) Limbs and joints: 0.06 mSv (6 mrem) WebAug 7, 2024 · A second kind of space radiation travels even farther than solar energetic particles. Galactic cosmic rays — particles from long-gone, exploded stars elsewhere in the Milky Way — constantly bombard the solar system at near-light speeds. If solar energetic particles are a sudden downpour, galactic cosmic rays are more like a steady drizzle.
WebThe amount (dose) of radiation you get from air travel is low, but the dose depends on a few factors. These levels of radiation are small and unlikely to affect human health. 1. Duration of the flight. The longer you are on a flight, the more radiation you receive. 2. Altitude. The higher you are in altitude, the higher the dose of radiation.
Webquantum event (absorption of an X-ray or gamma-ray photon) can cause ionization and subsequent biological damage due to the high energy content of the photon, which would be in excess of 10 eV (considered to be the minimum photon energy capable of causing ionization). Therefore, X-rays and gamma rays are examples ofionizing radiation.
