Radiation effects from the Fukushima Daiichi nuclear disaster times the safety limit, Professor Yasuyuki Muramatsu at the Gakushuin University urged detailed checks on wild plants and animals. Radioactive caesium in soil and fallen leaves in forests in his opinion would be easily absorbed by mushrooms and edible plants. He said that wild animals like boars were bound to accumulate high levels of radioactivity by eating contaminated mushrooms and plants. The professor added that detailed studies were on wild plants and animals. Across Europe the Chernobyl-incident had likewise effects on wild fauna and flora. The first study of the effects of radioactive contamination following the Fukushima Daiichi nuclear disaster
Caesium chloride give the poorly soluble double salt, e.g.: Treatment of the double salt with hydrogen sulfide gives CsCl: High-purity CsCl is also produced from recrystallized (and ) by thermal decomposition: Only about 20 tonnes of caesium compounds, with a major contribution from CsCl, were being produced annually around the 1970s and 2000s worldwide. Caesium chloride enriched with caesium-137 for radiation therapy applications is produced at a single facility Mayak in the Ural Region of Russia and is sold internationally through a UK dealer. The salt is synthesized at 200 °C because of its hygroscopic nature and sealed in a thimble-shaped steel
