Bean plants were grown to maturity in nutrient solutions and soils to study the influence of Cs and K on the growth and uptake of K, Cs/sup 137/, and stable Cs. The application of K to Cs/sup 137/-treated soils relatively high in exchangeable K had only slight effect on the plant uptake of Cs/sup 137/. Increasing additions of K to Cs/sup 137/-treated nutrient solution decreased the uptake of Cs/sup 137/. In both soils and nutrient solutions, the application of K increased the K uptake by plants… Expand

Influence of organic matter on the availability of certain elements to barley seedlings grown by a modified neubauer method
TLDR
The influence of organic matter on the availability of 17 elements to barley seedlings grown by a modified Neubauer technique was determined and the average N and K concentrations were consistently increased in the plants grown in soils with added organic matter. Expand
Effects of potassium in reducing the radiocesium translocation to grain in rice
TLDR
It is revealed that K supply has an influence on reducing 137Cs translocation from leaves to ears as well as decreasing 137Cs uptake by roots, revealing the importance of maintaining an appropriate soil K concentration during the early growth stages to avoid 137Cs contamination of rice grains.

134Cs Uptake and Growth at Various Cs+ and K+ Levels in Arabidopsis AtKUP7 Mutants
TLDR
Another mutant line in AtKUP7 is investigated and it is found that the growth phenotype of the kup7 mutants in K+ deficient conditions is much milder than previously published and their accumulation of K+ in shoots is hindered only by severe potassium shortage. Expand
Monovalent-ion carrier effects on transport of Rb86 and Cs137 into bush bean plants
SummaryBush bean plants were exposed to either Rb86 or Cs137 for 24 hours with different monovalent cations as carriers in single-salt solutions except for the presence of 10−4M CaCl2. Ratio of… Expand
Quantification of Cs, K, and Rb in rice (Oryza sativa) cultivated under paddy and upland conditions
Abstract In Asian countries, paddy rice ( Oryza sativa ) has been cultivated as a main crop for many years, but cesium uptake by rice has only been studied recently. As a result, the effect of land… Expand
Genotypic differences in the uptake and distribution of radiocaesium in plants
TLDR
It is concluded that crop selection as a measure to reduce 137Cs contamination of the food chain should not occur without taking into consideration the external K+ concentration. Expand
137Cs uptake in spring wheat (Triticum aestivum L.cv. Tonic) at varying K supply
TLDR
The predictions of 137Cs AC's in the shoot are qualitatively correct for the fertiliser effects but underestimate the observations between 1.4 and 9.9 fold, due to the increased NH4+ concentration in soil solution. Expand
THE EFFECT OF POTASSIUM ON THE UPTAKE OF 13’Cs IN FOOD CROPS GROWN ON CORAL SOILS: COCONUT
The soils of Bikini Atoll (11’ 35’N, 165” 25’E) were contaminated by fallout from a thermonuclear explosion in 1954. Today, in the absence of any treatment, intake of I3’ICs via the terrestrial food… Expand
Cesium Toxicity in Arabidopsis1
TLDR
Arabidopsis plants were tested for Cs intoxication resulting from competition between K+ and Cs+ for K+-binding sites on essential proteins, and the changes in gene expression in Cs-intoxicated plants differed from those of K-starved plants, suggesting thatCs intoxication was not perceived genetically solely as K starvation. Expand
Stable and radioactive cesium: A review about distribution in the environment, uptake and translocation in plants, plant reactions and plants' potential for bioremediation.
TLDR
This review summarizes investigations about sources of stable and radioactive cesium in the environment and harmful effects caused by internal and external exposure of plants to radiocesium and gives an overview over the uptake capacities of 72 plants for cedium from the substratum to the biomass.

Experiments were conducted to study the influence of stable K and Cs amendments on the uptake of Cs/sup 137/ by Ladino clover upon prolonged cropping of contaminated soils. The addition of K to soils… Expand
Relative Uptake and Translocation of Potassium and Cesium in Barley.
The relative rates of uptake of potassium and cesium by excised roots and by intact plants of barley from solutions have been measured by K/sup 42/ and Cs/sup 137/. The results have been expressed as… Expand
INFLUENCE OF STABLE Cs AND K ON THE REACTIONS OF Cs137 AN K42 IN SOILS AND CLAY MINERALS
TLDR
Under conditions of low ionic concentration, stablemore » Cs was much more effective than K in releasing Cs/sup 137/ from soils, however, K may be, in certain soils, as effective as stable Cs in high concentraltions. Expand
Accumulation of Potassium, Cesium, and Rubidium in Bean Plants Grown in Nutrient Solutions.
Adding potassium to the nutrient substrate reduced Cs/sup 137/ and Rb/sup 86/ uptake by bean plants less than expected from an assumed physiological equivalence of these ions. Plants discriminated… Expand
Effect of various cations upon absorption of carrier-free cesium.
TLDR
The uptake of carrier-free Cs/sup 137/ was found to be strongly temperature dependent and is therefore largely the result of metabolic absorption rather than of difiusion and adsorption phenomena. Expand
A KINETIC STUDY OF THE ABSORPTION OF ALKALI CATIONS BY BARLEY ROOTS.
TLDR
Evidence will be presented for the existence of several distinct reactive sites involved in the binding of alkali cations by barley roots, and it will be demonstrated that there are large differences in the affinity of these sites for various cations. Expand
Some Observations on Absorption of Cesium by Excised Barley Roots.
Steady-state cesium absorption was studied in relation to the external cesium concentration and under conditions of low temperature and anoxybiosis. The results are tentatively explained on the basis… Expand
Cs137 Biospheric Contamination from Nuclear Weapons Tests
Weapons tests to the end of 1957 have produced about 6 and 11 Mc of Sr90 and Cs137, respectively, of which about 1.9 and 3.4 Mc have been deposited as long-range fall-out. Average surface deposition… Expand
Dietary Considerations of the Radionuclide Contamination of Nonmilk Foods

In this country at the present time, milk and milk products contain the highest relative proportion of these fission products; however, nonmilk foods, especially vegetables and cereals, contribute more Sr90 to the total diet when considered as an entity. Expand
Radioactivity of People and Milk: 1957
TLDR
Little change in the cesium-137 concentration in people was observed from 1956 to 1957, in spite of the increase in both the rate and the integrated levels of fallout. Expand
