Mindblown: a blog about philosophy.

  • Objective lens

    Within an image intensifier, there exists a lens responsible for gathering the light emitted from the output screen and projecting it into the camera lens.  

  • Nuclear radiation

    The emission of neutrons, gamma particles, and other particles from an atomic nucleus as a consequence of nuclear fission or nuclear fusion.  

  • Nuclear particle

    A constituent of the atomic nucleus, which can be either a proton or a neutron. It is also commonly referred to as a nucleon. Additionally, a particle discharged from an atomic nucleus, such as an alpha particle or a beta particle.  

  • Nuclear emulsion

    A specialized photographic emulsion crafted to detect and record individual pathways of ionizing particles, such as those employed in scan recording.  

  • N shell

    The fourth electron shell encircling the nucleus of an atom, housing electrons distinguished by the principal quantum number 4.  

  • North pole

    The extremity of a magnet from which magnetic lines of force emanate.  

  • Nonvisualization

    The incapacity to render an organ discernible on radiographic film or to capture the desired level of image clarity and sharpness.  

  • Nonscreen holder

    An x-ray film holder devoid of screens, specifically designed for nonscreen radiographic procedures.  

  • Nonscreen film

    Alternatively referred to as direct-exposure film, this particular type of film relies primarily on direct x-ray exposure and is best suited for nonscreen radiographic applications. Notably, this film exhibits approximately fourfold greater sensitivity compared to screen film, resulting in the need for only one-fourth of the exposure time to achieve equivalent radiographic density.  

  • Nonmagnetic

    Certain substances lack magnetic properties and therefore remain unaffected by magnetic fields. Illustrative instances encompass air, glass, paper, and wood.
