  • Beta decay

    Radioactive metamorphosis of a nuclide entails an intriguing process whereby the atomic number experiences a precise alteration, either ascending or descending by a unit of one, while the mass number remains unaltered. The augmentation of the atomic number occurs through the emission of a negatively charged beta particle, also known as a negatron, while its…

  • Beamsplitter

    An optical component employed for the purpose of splitting a light beam, enabling its simultaneous projection in two distinct orientations.  

  • Beam restrictor

    Metallic apparatus affixed to the housing of the x-ray tube, serving the purpose of constraining the emitted beam to a specific field of interest, encompass a range of components such as aperture diaphragms, cones, and collimators.  

  • Beam flattening filter

    In betatrons and linear accelerators, a distinct filter is employed for x-ray beams to achieve flat isodose curves. This specialized filter plays a crucial role in ensuring that the distribution of radiation doses remains uniform and consistent throughout the treatment area.  

  • Beam barrier

    Based on the relevant table found in Handbook 76, it is indicated that the average diagnostic tube necessitates a lead shielding measuring approximately 1.5 mm (equivalent to 1/16 inch) in thickness. This lead shielding is employed to ensure proper protection and containment within the diagnostic tube.  

  • Base fog

    On the H & D curve, there exists a density known as base density, which registers below 0.25 on the scale. This particular density refers to the density exhibited by the x-ray film itself, often referred to as the base density.  

  • X-ray film base

    The translucent layer consists of a thin polyester plastic material measuring approximately 0.2mm (equivalent to 8 mils or 0.008 inches) in thickness. Typically, this material is imbued with a tint of blue-violet or green, rendering it sensitive to those hues. The foundation of the sheet contains a coating of silver bromide crystals on both of…

  • Barium strontium sulfate

    An illuminating substance employed in the production of intensifying screens.  

  • Barium platinocyanide

    Utilized in the fabrication of enhancing displays, the chemical compound played a pivotal role in Dr. W. C. Roentgen’s breakthrough discovery of X-rays.  

  • Barium lead sulfate

    A luminescent substance employed in the production of amplifying panels.
