Japanese nuclear experts have restored the cooling system at the generating units 5 and 6 of the Fukushima Dai-ichi nuclear complex, which was badly affected by a powerful earthquake and tsunami.
The cooling system at units 1 and 2 is due to be restored today, while on Sunday, the cooling system is expected to be brought back to normal at units 3 and 4, where the situation is seen as the most dangerous.
All signs are that the core zone of reactor 3 has melted down, and a massive release of radiation is quite likely there.
To avoid this, water is being poured on the reactor.
The reactor of generating unit 4 has no fuel, but it contains spent fuel rods that are a threat.

Contamination in Food Products around Fukushima
The Japanese Ministry of Health, Labour and Welfare has confirmed the presence of radioactive iodine contamination in food products measured in the Fukushima Prefecture, the area around the Fukushima Daiichi nuclear power plant. According to the latest data, the food products were measured from 16-18 March and indicated the presence of radioactive iodine. To date, no other radioactive isotopes have been shown to increase in the analysis of food products around Fukushima.
Though radioactive iodine has a short half-life of about 8 days and decays naturally within a matter of weeks, there is a short-term risk to human health if radioactive iodine in food is absorbed into the human body. If ingested, it can accumulate in and cause damage to the thyroid. Children and young people are particularly at risk of thyroid damage due to the ingestion of radioactive iodine.
Japanese authorities have implemented two critical measures to counter the contamination of food products by radioactive iodine. First, on 16 March, Japan's Nuclear Safety Commission recommended local authorities to instruct evacuees leaving the 20-kilometre area to ingest stable (not radioactive) iodine. As an established method of prevention, the ingestion of stable iodine can help to prevent the accumulation of radioactive iodine in the thyroid. Stable iodine pills and syrup (for children) have been made available at evacuation centres. Second, the Ministry of Health, Labour and Welfare has ordered a stop to the sale of all food products from the Fukushima Prefecture.
The IAEA has passed this information to the Food and Agricultural Organization of the United Nations (FAO) and the World Health Organization (WHO) and will continue to report on this development.
According to materials on its website, the FAO is prepared to respond upon request from the Government of Japan in the following areas:
* - assessing radioactive contamination of the agricultural environment, especially foods
* - providing technical advice and determining appropriate medium- and long-term measures for agriculture -- including soil, land, forests, crops, fisheries, animal health and welfare and food safety
* - facilitating international trade of foods, including agricultural produce
The IAEA continues to gather information on this development and will report further as events warrant.
@ Zelenim Eko-fajterima
Svet je jednostavno prinudjen na koriscenje atomske energije, alternative na zalost jos nema na horizontu.Nikakve vetrenjace,solarni paneli i slicna resenja ne mogu da podmire rastucu glad za energijom i to ne moze da promeni ni najgori moguci ishod krize u Japanu.
Za progres cemo i zdravlje da zrtvujemo a sve ce se zavrsiti seobom prljavih i opasnih tehnologija u zemlje treceg sveta gde opet naravno predstavljaju veliku opasnost ali ce biti daleko od ochiju javnosti bogatih zemalja.
Poboljsace se dizajn i povecati sigurnosne mere ali gradnja NE nece prestati naprotiv bice ih sve vise,zato ne troshite reci na priche o ekologiji potrebna je mnogo veca havarija od ove da bi se nesto promenilo.
Nije svet prinudjen vec ga prinudjuju oni koji vode ceo ovaj cirkus i ciji je jedini intertes profit
Alternativa uvek postoji.
Prljave tehnologije se odavno uvaljuju zemljama treceg sveta.
Po tebi znaci ne treba pricati o ekologiji uopste, zaboraviti na problem? Treba pricati o tome na svakom koraku, i jacati svest ljudi o istom.
Ne mogu da se mere Japan - svetska sila i Haiti, zemlja bede. Ulaganja u zastitu od prirodnih katastrofa u te dve zemlje - ko nebo i zemlja.
Po nekim svezim podacima,talas cunamija je bio visok preko 13 metara...:zgran:
