Progress report: Radionuclide transport in the Pasco to Vancouver, Washington, reach of the Columbia River, July 1962 to September 1963

The disposition of radionuclides in and along the 380-mile reach of the Columbia River between the Hanford, Wash., Atomic Energy Commission reactors (the major radionuclide source) and the head of the estuary is a first step in understanding the environmental cycling and ultimate fate of the discharged radioactive materials. Preliminary results for the study period, July 1962 to September 1963, are presented for radionuclide, sediment, and water data from stations on the Columbia River and from stations near the mouths of the Snake River, the Willamette River, and other Columbia River tributaries.

Progress report II: Assays and analyses of pyritic core from Wadi Wassat gossan, Saudi Arabia

Assays of 31 samples of pyritic core from diamond drill holes under gossan at Wadi Wassat, Saudi Arabia, disclosed 0.02 oz/ton gold in five samples, and from 0.11 to 1.68 oz/ton silver in 23 samples: The tenors are too low to constitute ores of either metal. Further work is required to learn if the tenor in silver varies with depth below the ground surface, with geologic unit, or both. No apparent relation exists between the estimated amount of pyrite in the core and the amount of silver disclosed by the assays.
