Regarding the July 28 article "Threat to food chain grows as contamination spreads": In this article, and in a number of others, I have seen the following statement: "On June 6, the Nuclear and Industrial Safety Agency said the plant released about 770,000 terabecquerels of radioactive material into the air between March 11 and 16, doubling an earlier estimate."

It is now almost August, and what I haven't seen is any current estimate of the total radiation released from the Fukushima No. 1 nuclear plant to date. This information is important not only to the people of Japan but also to those around the world who are trying to understand the nature and extent of the nuclear power plant disaster, and how it might apply to other reactor complexes.

The opinions expressed in this letter to the editor are the writer's own and do not necessarily reflect the policies of The Japan Times.
