Rapid, Nondestructive Determination of Beryllium Using Van de Graaff X-Rays.
A method is described for the rapid nondestructive analysis for beryllium utilizing the well known Be/sup 9/( gamma ,n)2 alpha reaction. The gamma rays were produced by conversion in a tungsten target of electrons accelerated by a Van de Graaff machine. Some of the neutrons resulting from the reaction of the gamma rays with beryllium were captured in a silver disk to produce radioactive silver isotopes. The induced radioactivity was counted with a Geiger-Muller tube apparatus and was proportional to the beryllium content of the irradiated sample. The average time required for a determination was 4 minutes. With a 20-gram sample, the limit of detection in a single determination was 0.002%. (auth)
