Targeted alpha therapy with bismuth-213 and actinium-225: Meeting future demand.

Targeted alpha therapy (TAT) is a promising approach for the treatment of cancer. The use of alpha emitters for cancer therapy has two distinct advantages over conventional therapies. The short range of alpha radiation in human tissue (less than 0.

Alpha Radiation-Induced Luminescence by Am-241 in Aqueous Nitric Acid Solution.

When exposed to air, alpha particles cause the production of light by exciting the molecules surrounding them. This light, the radioluminescence, is indicative of the presence of alpha radiation, thus allowing for the optical sensing of alpha radiation from distances larger than the few centimeters an alpha particle can travel in air. While the mechanics of radioluminescence in air and other gas compositions is relatively well understood, the same cannot be said about the radioluminescence properties of liquids.
