Natural thorium decays very slowly compared to many other radioactive materials, and the emitted alpha radiation cannot penetrate human skin. As a result, handling small amounts of thorium, such as those in gas mantles, is considered safe, although the use of such items may pose some risks. Exposure to an aerosol of thorium, such as contaminated dust, can lead to inc… Web20 de jun. de 2024 · They eventually established a thorium "cow," from which they could regularly "milk" actinium-225. In August 1997, they made their first shipment of actinium-225 to the National Cancer Institute. Currently, scientists at ORNL "milk" the thorium-229 cow six to eight times a year. They use a technique that separates out ions based on their …
