On today's two editions of the programme (one for those of you in the States as your clocks have changed, another at the usual time for everyone else) we'll simply continue what we've done ever since Friday. 成人快手 correspondents, experts on nuclear facilities, aid workers, and some of you affected by the disaster, will share experiences and answer some of the key questions being raised around the world. If you want to get in touch, post here, or on facebook, or on twitter. The live page is the best way to follow the story.
James in Seoul emails: We live in South Korea and would like to know whether there is any danger of nuclear fallout in case of a complete meltdown and/or explosion at the Japanese plants. What protective measures if any should we take?

Silvina Castro in Buenos Aires emails: Can you explain why they built so many nuclear plants in a country with a high risk of natural disasters? I'm not against nuclear power, but a minimum risk evaluation is absolutely essential.

Dale in Seattle This catastrophe has severe environmental implications not only in Japan but for example here on the West Coast of the United States. To me, it indicates the abandonment of atomic power plants around the world due to these these unforseen problems.

Gerry in Japan emailed the 成人快手: My wife and I are in Gifu, very far from the incident. We plan to fly to Canada at the end of the month, or sooner, if possible. She is about seven months pregnant. What danger does the present situation, or a more severe situation, present to our baby?

Glenn in California emails: Is it true that Japan has 55 nuclear power plants? Is it true that these plants only supply one third of Japan's energy needs? If so, the promise of nuclear energy as a safe and viable way to create electricity is insane. If it can be so dangerous in a country known for it's safety then well duh! Time to dismantle any defence for nuclear energy.

Alan in London emails: My son and daughter-in-law live in central Tokyo. My daughter in law is hoping to get pregnant this year. Would you recommend that they leave Tokyo and go to the other side of Japan - where her parents live, to avoid risk of radiation contamination.

Angela in India emails: I heard there is 60 to 70 tons of uranium in reactor number three. I also heard there are holes in the pipes carrying the coolant and this could be the reason why the cores are not cooling. Do you have any idea of what the consequences of a meltdown of 60 to 70 tons of Uranium will be? Also if all of Japan's reactors have such massive amounts of nuclear fuel, how have they been disposing their nuclear waste up until now?

Romulo in the Philippines: Are there guidelines for where a nuclear plant is located? Japan is in the "pacific ring of fire" so why is it that it is allowed to operate nuclear plants? Aside from it being a "peaceful" country and it needs tremendous amount of energy to generate enough power, can it justify the clear risk it is posing to nearby countries in times like this?
