Example of a natural radioisotope and its use
WebNov 20, 2024 · Radioisotopes are the unstable form of an element that emit radiation to transform into a more stable form. Radiation is easily traceable and can cause changes in the substance it falls upon. These special attributes make radioisotopes useful in medicine, industry and other areas. Of the 118 elements listed in the periodic table, only 94 occur ... WebRussia is keen to increase its share of world supply, and in 2012 some 66% of its radioisotope production was exported. For I-131, 75% is from IRE, 25% from NTP. World demand for Mo-99 was 23,000 six-day TBq/yr* in 2012, but has apparently dropped back to about 19,500 since.
