The industry ministry said Monday it would be safe to release water contaminated by the Fukushima nuclear disaster into the ocean, stressing that on an annual basis the amount of radiation measured near the release point would be very small compared to levels to which humans are naturally exposed. Discharging the water into the Pacific Ocean over the course of a year would amount to between just one-1,600th and one-40,000th of the radiation to which humans are naturally exposed, the Economy, Trade and Industry Ministry, or METI, told a government subcommittee on the issue. Water used to cool the melted-down cores and groundwater from close to the damaged plant contain some radioactive materials, and are currently being collected and stored in tanks on the plant grounds. But space is running out fast, and the government is exploring ways to deal with the waste water — which already totals more than 1 million tons with the volume increasing by more than 100 tons every day.

Tokyo Electric Power Holdings Co. on Nov. 18 released for the first time an estimate of the annual disposal amount of radioactive tritium from its crippled Fukushima No. 1 nuclear power plant. The volume will vary from 27 trillion to 106 trillion becquerel, depending on the commencement date and ending time of the disposal process, according to a report the utility presented to a subcommittee of the Ministry of Economy, Trade and Industry. In comparison, a domestic nuclear power plant in operation usually dumps liquid radioactive waste that contains tritium, a radioactive form of hydrogen, from several hundred billion up to 100 trillion becquerel annually into the ocean, according to the ministry.
