We are still seeing high levels of iodine-131 in Japanese sewage sludge. Radioactive iodine causes thyroid cancer and other thyroid diseases. Emission of this isotope indicates re-criticalities of nuclear fuel are ongoing. This means the coriums which have escaped containment and gone underground are cyclically heating up. As long as iodine-131 is found, there is no reason to expect that radioactive emissions from Fukushima will stop for thousands of years.
This Tepco webcam video edited by Nuckelchen shows that huge emissions from Fukushima are still occurring.
The entire planet is being contaminated with radiation, yet there seems to be no will to do anything about it, or inform the public of the danger. This is global genocide.
