artificial radioactivity

dirbtinis radioaktyvumas statusas T sritis apsauga nuo naikinimo priemonių apibrėžtis Dirbtinių radionuklidų, kuriais virsta neutronų veikiami stabilieji elementai, aktyvumas. Natūralių ir dirbtinių radionuklidų jonizuojančioji spinduliuotė nesiskiria. Žinoma maždaug 1700 dirbtinių radionuklidų, pvz., ²³⁹Pu, ¹⁴C, ⁹⁰Sr, ¹³¹I, ¹³⁷Cs ir kt. Dirbtiniai radionuklidai sukuriami branduoliniuose reaktoriuose, sprogstant branduoliniam užtaisams. atitikmenys: angl. artificial radioactivity rus. искусственная радиоактивность ryšiai: dar žiūrėkbranduolinio ginklo liekanos dar žiūrėksukeltasis radioaktyvumas
