radioactive series – a succession of elements initiated in the radioactive decay of a parent, as thorium or uranium, each of which decays into the next until a stable element, usually lead, is produced.

radioaktivlik – elementning yadroidagi o'zgarishlardan kelib chiqadigan o'z-o'zidan tarqaladigan radiatsiya, ma'lum elementlarning o'ziga xos xususiyati bo'lgan va namoyon bo'ladigan fenomen.		radioactivity – the phenomenon, exhibited by and being a property of certain elements, of spontaneously emitting radiation resulting from changes in the nuclei of atoms of the element.
radioizotop – radioaktiv izotop, odatda sun'iy ravishda ishlab chiqariladi: fizik va biologik tadqiqotlar, terapevtikalar va boshqalar.		radioisotope – a radioactive isotope, usually artificially produced: used in physical and biological research, therapeutics, etc.
radiouglerod – bundan tashqari, uglerod 14 deb nomlanadi. Massasi 14 ga teng bo'lgan uglerodning radioaktiv izotopi va taxminan 5730 yilga teng yarim umrga ega: organik materiallar tarixida keng qo'llaniladi		radiocarbon – also called carbon14. A radioactive isotope of carbon with mass number 14 and a half-life of about 5730 years: widely used in the dating of organic materials
