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.	radioaktiv qator – ota-onaning radioaktiv parchalanishida boshlangan elementlarning ketma-ketligi, har biri barqaror elementga, odatda, olib kelgunga qadar parchalanib ketadigan toriy va uran kabi
	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.			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.
	radiocarbon – also called carbon 14. 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			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
	radioisotope – a radioactive isotope, usually artificially produced: used in physical and biological research, therapeutics, etc.			radioizotop – radioaktiv izotop, odatda sun'iy ravishda ishlab chiqariladi: fizik va biologik tadqiqotlar, terapevtikalar va boshqalar.
	radium – a highly radioactive metallic element whose decay yieldsradon gas and alpha rays. Symbol: ra; atomic weight: 226; atomic number: 88			radiy – yuqori radioaktiv metall elementi, bu parchalanish natijasida gaz va alfa nurlari paydo bo'ladi. Ramz: ra; atom og'irligi: 226; atom raqami: 88.
