La période est une caractéristique propre à chacun des corps radioactifs; elle ne dépend ni de la quantité ni de l'état de ces corps. La période «effective» d'un isotope déterminé est le temps pendant lequel le nombre des noyaux présents dans le corps humain a diminué de moitié, en raison de la désintégration des noyaux et de l'élimination biologique. 7, record 2, French, - p%C3%A9riode%20radioactive
