WebMar 5, 2024 · Did you know that gold can be used to shield against radiation? NASA has been using the yellow metal in helmet visors since the 1960s. An ultra thin layer of gold … Gemstone irradiation is a process in which a gemstone is artificially irradiated 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. As a result, the gemstone's color may be significantly altered or the visibility of its inclusions may be lessened. trumark inc sorrento https://fredstinson.com
