Following the upgrade of the severity rating of the nuclear crisis at Fukushima to the highest level, the Green Party is calling upon the UK government to give full and frank information on the levels of contamination found to date in the UK; for continuing updates; and for their comments on the CRIIRAD advice to pregnant women and children in France.

Penny Kemp, environment spokesperson for the Green Party said: "Nobody wants to be alarmist, but people are understandably worried about nuclear contamination. We must be given accurate and up-to-date information.

"In France, The Institute for Radiological Protection and Nuclear Safety has found iodine-131 in milk. Normally, no trace of iodine-131 should be detectable in rainwater or milk. Iodine 131 was a significant contributor to health effects from open-air atomic bomb testing in the 1950s and from the Chernobyl disaster in the 1980′s, which is still causing problems in some parts of Wales and the Lake District.

Kemp continued: "Japan has also extended the evacuation zone around the damaged nuclear plant because of radiation concerns. While Greens understand that the decision reflects total radiation at Fukushima, in the wake of further aftershocks, our call is for more openness and more accurate, up-to-date information on an issue of serious concern."
