Domain nuclear safeguards system - safeguards
  • a body of material intended to reduce the intensity of radiation entering a region
  • a structure made of shielding material to reduce radiation levels
  • protective use of low atomic number materials to thermalize strong neutron beams, or concrete, lead or other heavy materials to shield against gamma radiation when it might be harmful to operator or measuring system. Concrete is commonly used for large areas and lead for smaller.
  • dense material, such as depleted uranium, concrete or steel, used to reduce the intensity of ionizing radiation and thereby provide protection for people from radiation
shielding
Usage examples
  • Sketch of critical assembly core showing core support structure, shielding and heat removal arrangements with description (to be provided for each critical assembly if more than one in the installation).

  • kiirgust neelav(ad) materjal(id), mida kasutatakse personali, patsientide ja teiste kiirgusallika läheduses viibivate isikute kaitseks ioniseeriva kiirguse eest; võib tinglikult jagada allika- (nt röntgentoru kaitsekest) ja struktuurvarjestuseks (ehituskonstruktsioonid: seinad, laed, jmt); sobiv kiirgusvarjestuse paksus arvutatakse vastavate üldtunnustatud meetodite (NCRP või BIR/IPEM) abil, arvestades kiirgust neelava materjali omadusi, kiirgusallika koormust (mA×min/nädalas), summaarset DAPi, naaberruumide hõivet, naaberruumides viibivate isikute doosi piirmäärasid jne
