Abstract
A technique for measuring the direction of movement of sandy sediments by means of a radiotracer is described. An artificial sediment fabricated from glass containing a small percentage of arsenic is irradiated in a nuclear reactor to produce 76As (T1/2 = 26.4 hr). This material is then inserted into the particular sediment to be studied and its movement followed by monitoring the 560-keV v-ray emission with a submersible NaI detector. A test of the method at Point Pelee on the north shore of Lake Erie with 140 g of artificial sediment containing 180 mCi of 76As demonstrated that the redistribution of the radioactive material by the bottom current could be readily followed for at least three days after insertion.
