The method of determination of vanadium and aluminum in graphite was studied. In the method, sample is placed for 3 minutes in the nuclear reactor JRR-1 to be irradiated by neutrons at a flux of 3 x 10/sup 11/ neutrons per sq. cm per second, and then counted for 2 minutes by 2 in. thlck sodium iodide crystal connected with a 256-channel pulse height analyzer. The photopeak height due to vanadium-52 and that due to aluminum-28 are measured respectively. Vanadium and aluminum are thus determined simultaneously, when comparative standards are used. Both of the elements could be determined down to a 10/sup -1/ ppm. The estimated coefficient of variation of single determinations is about 10% for 0.1 ppm vanadium, and about 20% for 0.2 ppm aluminum. (auth)
