EDIT: They indeed did so, but shortened and dumbed it down with only 2 figures being provided by 'WLJG'--2.3 and 6.4 mSv 'near the plant', with the latter being the peak at the time of 'leak.'

Here are the latest ones for Fukushima-daiichi:

The columns are, in order, date, time, location (often 正門, the main gate), gamma rays, neutron radiation, wind direction, wind speed. The latest peak seems to be 10.85 mSv/hr at 12:30PM on the 16th, down to 2.5 mSv/hr less than one hour later.
