Japan’s Tokyo Electric Power Company discharged radioactive contaminated water into the sea three times last year.
Seven additional releases are scheduled to be released this year.
Reporter Oh Yu-rim visited Marado, the southernmost part of the country where radioactive materials arrive first.
◀ Report ▶
In 2011, a magnitude 9.0 earthquake struck Japan, causing radiation to leak from the Fukushima nuclear power plant.
It was the worst nuclear accident in which the reactor melted down.

″The amount of radiation released in a year was released in just one hour.″
A radiation monitoring station installed in Marado, the southernmost part of the country.
It was installed the year following the nuclear accident as the first destination for radioactive materials leaked from the Fukushima nuclear power plant.
The radiation value measured on the last 7 days was 0.071 microsievert, which is normal.

″When special issues are identified, it can be said to be a very geographically important location where plans can be made in advance.″
It takes regarding 10 years for the discharged contaminated water to travel around the Pacific Ocean and reach our waters.
The problem is the amount and concentration of water scheduled to be discharged in the future.
Starting with the first discharge of 7,800 tons, 23,000 tons of contaminated water that went through the polynuclide removal facility and ALPS was discharged three times last year alone.
This is contaminated water containing the radioactive substance ‘tritium’, which has the lowest concentration but whose safety has not yet been verified.
The number has more than doubled to 7 this year, and the level of pollution is also strong.
The contaminated water discharged for the fourth time on the 28th of last month contained 1.4 terabecquerel of tritium, which is higher than the contaminated water last year.
Japan plans to discharge contaminated water into the sea seven times a year for 28 years and end discharge of contaminated water in 2051.
