The ALPS is a chemical system which will remove radionuclides to below legal limits for release. However, because tritium is contained in water molecules, ALPS cannot remove it, which gives rise to questions about the discharge of treated water to the sea.

In 2014 a new Kurion strontium removal system was commissioned. This is mobile and can be moved around the tank groups to further clean up water which has been treated by ALPS.

The clean tritiated water was the focus of attention in 2014. A September 2013 report from the Atomic Energy Society of Japan recommends diluting the ALPS-treated water with seawater and releasing it to the sea at the legal discharge concentration, with monitoring to ensure that normal background tritium levels are not exceeded

If you go inland, villages are deserted, most people literally left, there are closed off areas called red-zones, where no one can enter or live

There are other zones such as the orange zone where people are able to go but not to live

A recent study suggests that the radioactive material

released in the air by the Fukushima nuclear disaster has led to widespread negative effects such as population decline and genetic damage in the animals, insects and wildlife of the region.

There was a study on the pale grass blue butterfly which is the most common butterfly in Japan. They discovered that this species suffered a reduction size, reduction in growth, and high mortality and abnormality rates. However, their results also hinted thatthe Fukushima butterflies were evolving radiation resistance
