The international community needs to make a decision based on science.
Already, South Korea has asked the International Atomic Energy Agency to go ahead and conduct an inspection on-site to determine the extent of the problem with the contaminated water.
This article gives us the impression that the IAEA is ignoring the situation and there is some sort of conspiracy to cover up what is going on.
Perhaps more needs to be done, but the IAEA has done a lot of studies on Fukushima and is currently monitoring the contaminated water. There is a lot of information available on its website: https://www.iaea.org/newscenter/focus/fukushima/status-update
It should be mentioned that Korea is engaged in a serious trade war with Japan at the moment. They have a complex history and disagree over many issues. We should be cautious about trusting information coming out of Korea regarding Japan and use non-biased biased sources from 3rd parties.
There are even petitions to cancel the Tokyo 2020 Olympics because Fukushima is dangerous. They will not be having the Olympics next to the power plant.
No one has actually died from Fukushima radiation, they aren't even certain if levels of cancer are elevated. There are many places on earth where people live that have much higher background radiation due to natural causes. You will probably get more radiation on the flight over or from your annual medical check-up.
Again, don't trust me. We need facts from scientists, not opinions from people who are super skeptical about Japan in general.
