Regarding the March 16 article "Radiation fears grow after blasts": In the map-box for this article, radiation levels are stated in "millisieverts" for one time Tuesday morning (March 15), then in "microsieverts" for another time the same morning, thus rendering the information practically useless at a glance. There was no explanation of how many microsieverts equaled a millisievert, or vice versa. (In fact, 1 millisievert equals 1,000 microsieverts.)

It's disappointing that The Japan Times did not give clear information on the map, especially in times like these. That said, keep up the otherwise good work you are doing.
