Japan says radioactivity from nuclear discharge is within parameters – Observer

The first analyzes of the level of radioactivity in the water at the Japanese nuclear power plant in Fukushima, after the first discharge into the sea, were conclusive and within the parameters, guaranteed the operator who carried out the tests.

The level of radioactivity in the collected samples was in line with forecasts and below the maximum limit set at 1,500 becquerels/liter (Bq/L), said a spokesman for the operator that manages the nuclear power plant, TEPCO.

Fukushima: Japan to release radioactive waters from nuclear power plant into the Pacific Ocean. What is at stake?

The Japanese standard for this type of spill, inspired by the international standard, is 60,000 Bq/L. The becquerel is the unit of measurement of radioactivity adopted internationally in 1975 at the 15th Conference on Weights and Measures.

The designation of the unit (Bq) is based on the name of the physicist Antoine Henri Becquerel, winner of the Nobel Prize in Physics in 1903, together with Pierre and Marie Curie, for their studies on radioactivity.

China recalls Japanese ambassador after announcement of Fukushima discharges at sea

On Thursday, Japan began the discharge of water from the Fukushima nuclear power plant into the Pacific Ocean, “after treatments” that, according to the authorities, removed the “most radioactive waste“.

This is a process that will last for several decades, but which is generating strong protests in Japan and in the countries of the region, namely in the People’s Republic of China and the Philippines.

Tokyo Electric Power (TEPCO), the operator of the nuclear power plant, decided to start discharging after reporting that the concentration of radioactive waste was “within the stipulated parameters“.

According to the same entity, the purification of the plant’s water was subjected to treatment using an ALPS circuit (Advanced Liquid Processing System).

The first discharge occurs 12 years after the serious accident that hit the Japanese nuclear power plant.following an earthquake and tsunami in the Fukushima area.
