Recorded here are the results of post irradiation radiochemistry analysis of 800 MeV proton irradiated ultra high purity aluminum. Standard gamma-ray counting equipment, including a Ge Li detector, a multichannel analyzer, and associated electronics, was employed to count the /sup 22/Na activity in the activated aluminum. Since activation is proportional to proton fluence, relative dose levels can be determined. Also, use of a selected production cross section for /sup 22/Na in aluminum and a calculated damage energy cross section, both for 800 MeV proton bombardment, allows determination of a calculated value for the number of displacements per atom (dpa) that the material received during an irradiation experiment at the Clinton P. Anderson Meson Physics Facility (LAMPF). It is felt that simple and sufficiently accurate post irradiation dose determination can be made when either the subject material is ultra high purity aluminum or if this material is provided as a monitor with other subject materials, the simplicity being that the transmutation product, isotope /sup 22/Na, is relatively abundant and has a long half-life.
