Radioactivity levels of the Columbia River below Richland, Washington, April-June 1956
In the Columbia River downstream from Richland, Washington, there is a gradual decrease in concentration of radioactive isotopes. At any one location there are fluctuations due to factors such as dilution and decay time. During this period at all locations the concentration of alpha particle emitters in water averaged below the detection limit. Special analyses for uranium showed an average of 1.1 ..mu..g/cc (7 x 10/sup -10/ ..mu..c/cc). In mud, all alpha particle emitter concentrations were below the detection limit. Beta particle emitters in water upstream of McNary Dam decreased slightly due to increased river flow this quarter. Downstream from McNary Dam, beta particle emitter average concentrations in water were about the same as the past three quarters.
