Gemstone irradiation is a process in which a gemstone is exposed to artificial radiation in order to enhance its optical properties. High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice , which in turn alters the optical properties within it. [ 1 ]
bismuth (the radioactive isotope, 210 Bi, is found as a daughter product of Pb210 from Th in thorium minerals). These minerals emit alpha, beta and gamma ionising radiations, as well as radioactive gases such as radon and thoron. Appropriate precautions should be taken by collectors to store their specimens, especially to avoid inhaling radon gas..
In 1986, California named benitoite as its state gemstone, a form of the mineral barium titanium silicate that is unique to the Golden State and only found in gem quality in San Benito County. [ 80 ] ^ Colorado is the only state whose geological symbols reflect the national flag's colors: red (rhodochrosite), white (yule marble), and blue ...
Ekanite is an uncommon silicate mineral with chemical formula Ca 2 ThSi 8 O 20 or (Ca,Fe,Pb) 2 (Th,U)Si 8 O 20.It is a member of the steacyite group. It is among the few gemstones that are naturally radioactive.

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
