The effect of two months of frozen storage at -20 degrees C on the spoilage characteristics and shelf life of thawed and modified atmosphere packed (MAP) cod fillets stored at 2 degrees C was studied. Thawed MAP cod fillets were compared with fresh cod fillets stored in CO2-containing modified atmospheres with and without added oxygen. The shelf life of 11… (More)
Samples from sediment cores collected at 26 different locations 5 to 35 miles offshore in and around Astoria Submarine Canyon were analyzed for gamma emitters. Chromium-51 and zinc-65 were the principal radio-nuclides found, although several fission products and natural potassium-40 were also present. Radioactivity fell off sharply with distance from the… (More)
Marine organisms modify the distribution of radioisotopes in the oceanic ecosystem. Various vital processes of plants and animals concentrate elements. The distributions of the biota are often independent of their watery environment; they may actively migrate vertically or horizontally or may remain in place while the water moves past them. In the case of… (More)
Radioanalyses by gamma-ray spectrometry have been carried out on 37 samples of Euphausia pacifica obtained from a network of stations off the Oregon coast. Data on euphausiids taken from this area in November 1961 and in March and April 1962 are compared to show the variation in concentration of zirconium-95 and niobium-95, ruthenium-103, and cerium-141,… (More)
The plume of the Columbia River was followed 350 kilometers to sea by measurement of its chromium-51 content. This radioactive tag, introduced into the river by nuclear reactors at Hanford, Washington, promises to provide a useful oceanographic tool for determining rates of transport and mixing, and for identifying plume waters in the presence of other… (More)
Chromium-SI introduced into the Pacific Ocean from the Columbia River remains in the hexavalent state. Analysis of this radionuclide in sea water by hydroxide coprecipitation with iron is best accomplished if the chromium-51 is first reduced to the trivalent state.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2016-215396 DESCRIPTION We highlight a case of Milroy’s disease in a 28-year-old man. He originally presented with fleshy, exophytic coliform lesions that carpeted his scrotum and penile shaft (figure 1). His prior treatments… (More)
A "hot particle" containing only fission product radioactivity is comprised of a number of characteristics that make the particle unusual and its origin uncertain.
A probe for measuring emission of gamma-rays in sediments in situ in water depths to about 35 meters was used to measure radioactivity in the Columbia River estuary and Oregon coastal areas. This technique offers some advantage over methods in which sediment samples are collected at sea and returned to the laboratory for radioanalysis.
