The Japanese authorities says tests of seawater from astir the Fukushima atomic powerfulness works are showing nary detectable levels of radioactivity.

It is seeking to allay concerns from neighbouring countries and sportfishing groups astir the merchandise of treated h2o from the works into the ocean.

Weekly trial results volition beryllium published for the adjacent 3 months.

More than a cardinal tonnes of h2o stored astatine the atomic works volition beryllium discharged implicit the adjacent 30 years.

It has been accumulating since 2011 erstwhile the works was severely damaged by a tsunami.

Japan says the h2o is safe, and the UN's atomic watchdog has approved the plan, but critics accidental the merchandise should beryllium halted.

The h2o is being filtered to region astir radioactive elements past diluted to trim levels of tritium, a radioactive isotope of hydrogen which is hard to abstracted from water.

The Environment Ministry said samples from 11 locations adjacent the works showed tritium levels beneath 7-8 becquerels per litre, the little bounds of detection.

The h2o "would person nary adverse interaction connected quality wellness and the environment", it added.
