The absorption of cesium-137 and strontium-90 by vines, permanent pasture, potatoes, green vegetables, tomatoes, onions, cabbage, and beans in France in 1960 is presented. The strontium coefficient has varied very little from one year to the next and that of cesium has slightly diminished. The values obtained suggest that the ...

Absorption-oscillator-strength measurements for the principal series in cesium were measured using a

ABS>A process is given for selectively removing cesium from acid aqueous solutions containing cesium in microquantities and other cations in macroquantities by absorption on clinoptilolite. The cesium can be eluted from the clinoptilolite with a solution of ammonia, potassium hydroxide, or rubidium ...

A report is given of observations of the ionization of atomic cesium by the simulataneous absorption of three ruby laser quanta. The results appear to be in qualitative agreement with theory, and indicate that circularly polarized light produces ionizatio...

Particular attention is paid to the cesium iodide scintillators ... Complete cross sections of cesium iodide illustrating total absorption and fractional ...

The available data about the soil to plant transfer factor of cesium are numerous but very variable. The variation conditions of the transfer factor are studied with the help of laboratory experiments and the results analysed with the help of a multiple l...

Cesium atom concentrations in the range 10 exp 14 to 10 exp 17 cm exp -3 were determined in a pulsed argon-cesium MHD channel flow and in a gas at rest. Determinations were carried out by measuring the total absorption of radiation from an incandescent la...

Specific tasks under this program include investigations of the feasibility of a dynamic cesium flow system (Integral Cesium Reservoir) and the development and evaluation of single-crystal tungsten emitters incorporated in planar thermionic converters. Du...

The determination of micrograms of cesium in the presence of calcium and strontium using a Beckman DU flame spectrophotomcter is described. Both the precision and accuracy are 6.5% for cesium concentrations to 30 ppm and 2.5 to 5% for 40 to 50 ppm. (auth)

Absorption by Elodea cauadonesis Rich. Lemna minor L, and Ceratophyllum demersum L from various cesium solution concentrations from 10/sup -9/to 10/sup - 3/ g-eq//sub 1/ is discussed. A graph of elodea and lemna absorption from various concentrations indicates a direct proportionality between cesium ...

A concentration and an unselective elution are effected by an exchange resin. The cesium is absorbed on ammonium molybdiphosphate precipituted with hydrofluoric acid after radium elimination. The strontium is stripped in concentrated nitric acid, precipitated in the form of strontium ' carbonate, and then counted near the radioactive balance. The ...

Optical delays are observed for a pulse propagating through hot cesium vapor in the vicinity of peak absorption features. By tuning the pulse frequency across the absorption spectrum +/-20 GHz, delays up to 66 ns have been observed. In this experiment pulse delays are captured using a gated imaging camera system across the ...
