Radiation risks from Fukushima ‘no longer negligible’, EurActive, April 11, 2011:
The risks associated with iodine-131 contamination in Europe are no longer “negligible,” according to CRIIRAD [Commission de Recherche et d'Information Indépendantes sur la Radioactivité], an independent French research body on radioactivity. …
The document, published on 7 April, advises against consuming rainwater and says vulnerable groups such as children and pregnant or breastfeeding women should avoid consuming vegetables with large leaves, fresh milk and creamy cheese.
The risks related to prolonged contamination among vulnerable groups of the population can no longer be considered “negligible” and it is now necessary to avoid “risky behaviour,” CRIIRAD claimed. …
[This] is applicable to other European countries, as the level of air contamination is currently the same in Belgium, Germany, Italy and Switzerland, for instance.
Data for the west coast of the United States, which received the Fukushima radioactive fallout 6-10 days before France, reveals that levels of radioactive iodine-131 concentration are 8-10 times higher there, the institute says.
What level of radiation can be a risk?
The Euratom [European Atomic Energy Community] Directive of 13 May 1996 establishes general principles and safety standards on radiation protection in Europe. …
Beyond [ten micro sieverts per year], possible measures should be considered to reduce exposure, it says. …
CRIIRAD notes that the amount of iodine-131 capable of delivering a dose of 10 [microsieverts] varies greatly depending on the age of consumers. Children up to two years old are the most vulnerable and ingestion of 50 becquerel (Bq) is enough to deliver to the body a dose of 10 [microsieverts], according to the institute.
If the foods (leafy vegetables, milk etc.) contain between one and 10 Bq per kg or more, it is possible that the reference level of 10 [microsieverts] may be exceeded within two to three weeks, the institute added. …
