Metabolism of Cesium and Potassium in Swine as Indicated by Cesium-134 and Potassium-42

Radiocesium Distribution in the Tissues of Japanese Black Beef Heifers Fed Fallout-Contaminated Roughage Due to the Fukushima Daiichi Nuclear Power Station Accident

“…[6][7][8] Varying accumulation of radioisotopes among tissues in experimental and domestic animals has been found. [9][10][11][12][13][14][15] However, differences in radiocesium accumulation due to the nuclear accident among tissues in Japanese Black beef cattle have not been investigated under experimental control of feeding. This is the first study to demonstrate the distribution of radiocesium in tissues, including muscles of beef cattle fed roughage contaminated with radioactive fallout from the FDNPS accident by feeding experiment using roughage containing radiocesium at known concentrations.…”

“…Some reports state that the kidney and/or skeletal muscles accumulated high radiocesium. [9][10][11][12][13][18][19][20] These differences in cesium concentrations across tissues are considered to be attributable to differences in Na,KATPase activity. 12) In addition, a kinetic model of Cs flow in human body has been proposed, 21) in which plasma Cs accumulates in highly distributes into the kidneys and muscle.…”

Artificial environmental radionuclides in Europe and methods of lowering their foodstuff contamination – a review

“…Administration of potassium in the diet caused an increase in radiocaesium excretion (Mraz et al 1958;Mraz 1959;Johnson et al 1968), while the administration of stable caesium was not efficient (Oughton et al 1989;Rundo 1964). Different complexes or chelating additives are used successfully, with the ability to absorb and/or to bind radionuclides forming chemical compounds not absorbed by the digestive tract but easily excreted from the body (Giese 1988;Giese 1989;Pöschl and Baláš 1999;Pöschl and Řezáč 2004).…”

Complexes of <i>myo</i>-Inositol-Hexakisphosphate (IP6) with Zinc or Lanthanum for the Decorporation of Radiocesium

“…The biological half-life of 137 Cs is long and is approximately 100 d in male human adults. [6][7][8][9] These properties, coupled with internal exposure of 137 Cs, could be very harmful to humans. When exposure to 137 Cs occurs in humans, decorporation agents are useful for decreasing the absorbed radiation dose.…”
