Apparently the Japanese government has learned well from how official data is reported here in the US:
Make the first official report sound not too bad, then officially revise the numbers upwards months later buried in paragraph 5 of another positively spun report.
The Japs today officially upwardly revised their Fukushima radiation estimates by MORE THAN DOUBLE to 770,000 terabecquerels of total radiation released to date by the stricken nuclear complex.
Look for estimates to double again in the coming months.
From Kyodo:
The government's nuclear safety agency more than doubled its estimate Monday of the amount of radioactive materials emitted into the air during the early days of the nuclear crisis at the Fukushima Daiichi power plant, saying that the amount is believed to have totaled 770,000 terabecquerels.
The agency also issued its own assessment of the conditions of the Nos. 1 to 3 reactor cores based on the assumption that they suffered meltdowns, and pointed to the possibility that the process in the cases of the Nos. 1 and 2 reactors may have developed faster than estimated by plant operator Tokyo Electric Power Co.
The assessment by the Nuclear and Industrial Safety Agency is expected to be reflected in Japan's report on the accident to be submitted to a nuclear safety ministerial meeting hosted by the International Atomic Energy Agency later in the month.
