The proposed release of wastewater from the Fukushima Daiichi Nuclear Power Plant is controversial. I believe that the Tokyo Electric Power Company and the Japanese Government have developed a robust plan using their current radiation protection legalisation and practices to at least start disposing of water in the short term.
This approach has been verified by the IAEA in their subsequent reports. These include reports assessing the Japanese regulatory system, safety review missions, and corroboration of the independent sampling, data and analysis as well as inter-laboratory comparisons.
However, whilst this disposal plan meets the scientific and regulatory requirements for the disposal of radiation into the sea, and no environmental or human health impacts are likely to be observed, there is a growing question regarding the use of the sea as a dumping ground when our oceans are already stressed and struggling.
Dilution is no longer the solution to pollution, so whilst the Japanese may dispose of their wastewater in the interim, it would be a good opportunity to look at other disposal methodologies in the future. The Pacific Island Forum Scientific Panel has proposed to use the wastewater to make concrete, therefore locking up the residual radioactive tritium.
