Cesium Behaviour and Distribution in Man following a Single Dose of 137-cs.
r-RNS erhebt sich die Frage, ob sie außerhalb der Zelle so an Proteine gebunden wird, daß sie dem Zugriff der RNase entzogen ist, ob einige Moleküle in ganzer Kettenlänge oder von vielen Molekülen kleiner Anteile in die Zelle penetrieren. Aus weiteren Versuchsergebnissen geht hervor, daß zum indest ein Teil des 32P der r-RNS in hoch m olekularer RNS in der Zelle vorliegt. Das Schick sal und d...
متن کاملCesium-137 in Lake Michigan Sediments: Areal Distribution and Correlation with Other Man-made Materials
Grab samples of sediment were collected at 530 locations in Lake Michigan, primarily in the southeastern quarter of the lake. Each sample was analysed in the field and in the laboratory for fallout cesium-137. Twenty-five of the samples, collected near the mouth of the St Joseph River, were also analysed in the laboratory for 11 other man-made materials known to be discharged into the river. Tw...
متن کاملThe Tissue Distribution and Excretion of Cesium-137 following Inhalation-preliminary Data for Rats. Lf-4.
Data were obtained for the distribution-excretion pattern of cesium in rats over a period of 102 days following inhalation exposure. Three groups of 20 rats each were exposed to aerosols generated from solutions of "carrier' free", 1 and 8 per cent cesium chloride which contained cesium-137 as a tracer. Urine and feces of all rats were collected daily until sacrifice, and the time-tissue distri...
متن کامل01.09 Radioactivity in Soils (Cesium-134 and Cesium-137) (Edition 1992)
The reactor accident at Chernobyl on 26 April 1986 dramatically demonstrated the dangers involved in man-made radioactivity. The Chernobyl catastrophe was incomparably larger than the reactor accident in Harrisburg, USA in 1979. Chernobyl released enormous amounts of radioactive substances. Wind and weather dynamics transported these substances and deposited them onto the earth as radioactive d...
متن کاملSpatial Variability and Cesium-137 Inventories in Native Forest
With the nuclear fission discovery and development of nuclear weapons in 1940s, artificial radioisotopes were introduced in the environment. This contamination is due to worldwide fallout by superficial nuclear tests realized from early 1950s to late 1970s by USA, former URSS, UK, France and China. One of theses radioisotopes that have been very studied is cesium-137. Cesium-137 has a half-life...
