CE ÎNSEAMNĂ DOSE EQUIVALENT ÎN ENGLEZĂ?
Doza echivalentă
Doza echivalentă este o cantitate de doză ponderată la radiații care ia în considerare tipul de radiație ionizantă care produce doza. Doza echivalentă este utilizată în protecția radiologică pentru a reprezenta efectele stochastice, dar nu deterministe, ale radiațiilor ionizante.
Definiția dose equivalent în dicționarul Engleză
Definiția echivalentului dozei în dicționar este o cantitate care exprimă probabilitatea ca expunerea la radiații ionizante să provoace efecte biologice. Se obține de obicei prin înmulțirea dozei cu factorul de calitate al radiației, însă pot fi luați în considerare și alți factori. Se măsoară în sieverts sau rems.

Equivalent. Absorbed dose equivalent (ADE) is a method used to calculate the
effective absorbed dose for all types of ionizing radiation. It is known that not all
types of radiation are equal in their ability to cause biologic damage to living
tissue.
