A 10 cm 3 air saturated Fricke dosimetry solution in a 1 cm diameter tube is irradiated for 10 min in a 6~ source of gamma rays.

Trace amounts of rare clements are found within groundwater and are of interest to goochemists. Earopium and terbium are 30 - lanthanide-scries clements that can be measured from the intensity of their fluorescence emittcd when a solution is illuminated with ultraviolet radiation. Certain organic 25 - compounds that bind Eu(III) and Tb(IIl) enhance the cmission, and substances found in natural waters can decrease 20- the cmission. For that reason it is necessary to use standard Eu (II) additions to the sample to correct for such interference. The graph shows the result of such an cxperiment in which the 15- concentration of Eu(III) and Tb(III) was mcasured in a sample of groundwatler. The x-intercept of the Eu(III) plot is 10- -23.1 ml. and the x-intercept of the Th(III) plot is -9.91 ml. In cach case, 10.00 ml. of the sample solution and 15.00 ml. 5- Tb (III) of an organic additive were added to a scries of live 50 ml. volumctric flasks. The standard Eu(lI) or Th(III) solution (0,…
