work done on behalf of the U.S. Atomic Energy Commission, and includes information covering all known uranium and thorium-bearing minerals on a worldwide basis. Included are numerous tables and line drawings, and one b & w photo. Each mineral species is described according to its synonymy, composition, crystallography and crystal habit, physical properties, optical properties, synthesis, identification, natural formation, and occurrence. The descriptive mineralogy is followed by determinative tables in which the mineral species are arranged according to their X-ray powder-diffraction interplanar spacings, chemical composition, optical properties, color, specific gravity, and fluorescence. The work is documented by more than 800 references to the world literature of the past 200 years! This is an absolute reference for anyone interested in radioactive minerals! Published by the U.S. Government Printing Office, Washington, 1958. Original, new copy, printed in 1958.

The present study describes the synthesis of radioactive gold nanoparticle in surfactant medium. Proton irradiated stable 197Au and radioactive 198Au were simultaneously used for production of radioactive gold nanoparticle. Face centered cubic gold nanoparticles with size of 4–50 nm were found in proton irradiated gold foil. However, the size of nanoparticle varies with pH using both stable and radioactive gold.
