  • (21) Viitetase on avariikiirituse või püsikiirituse olukorras esinev efektiivdoosi, ekvivalentdoosi või aktiivsuskontsentratsiooni tase, millest kõrgema taseme puhul tuleb kaaluda meetmete võtmist kiirituse vähendamiseks, kuigi tegu ei ole piirmääraga, mida ei tohi ületada.
  • defineeritakse kõikide Eesti õigusaktide ulatuses
  • (21) Reference level means in an emergency exposure situation or in an existing exposure situation the level of effective dose, equivalent dose or activity concentration above which taking of measures has to be considered for decreasing the radiation, even though it is not any limit that may not be exceeded.
  • defined within the scope of all Estonian legal instruments
