Fe4[Fe(CN)6] can bind caesium therefore iron blue pigments are used in clinical practice as an antidote for the treatment of humans contaminated with radioactive caesium (see also Section 3.6.4). Clinical use of iron(III) ferrocyanide in doses up to 20 g/d for decontaminations of persons exposed to radio caesium has not been associated with any reported toxicity [3.209].

About lO becquerels of radioactive caesiums were released, and precipitated over a vast area. Exposure to caesium is difficult to prevent. Once it is deposited in the soil. 

Binding abilities of the soluble polymers fall down slowly with the concentration of alkali metals. In Figure 30.9, the results of UF/complexation with polyethyleneimine (PEI), polyacryhc acid of different cross-hnking (PAAl and PAA2) and polyacryhc acid amide were presented. In each case the decontamination factors for °Co decrease when concentration of alkah metals increase from 0.1 to 2.5 g/dm. The increase of alkali metals causes dechne of decontamination factor for radioactive caesium, while cyanoferrates are applied as a sorbents (Figure 30.10).

For example, naturally occurring clinoptilolite is used by BNFL to remove radioactive caesium and strontium from spent pile effluent. However, the synthetic zeolites, A and P, have had the greatest impact on the home. Sodium zeolite A rapidly exchanges its sodium atoms for the divalent hard water ions calcium and magnesium at room temperature. This discovery led to the replacement of the polyphosphates previously used in washing powder, which were damaging to the environment, by zeolite A about 20 years ago. More recently, Unilever introduced MAP (maximum aluminium zeolite P) as a replacement for. zeolite A. MAP has a lower water content, and is lighter in the packet ...

The content ofradioactive caesium in milk and meat of Hvestock depends mainly on the contamination of the feed. For example, cows resorb about 30% of radioactive caesium in the feed. In 1986,... 

The inorganic salts used to prepare the synthetic feed solutions (NaNOa, HNO3) were analytical-grade products from Prolabo and Aldrich. Radioactive Caesium was provided by the Amersham company.
