Radiation Levels Decreasing, Per TEPCO Data

We understand these numbers are given by TEPCO, so take them with a grain of salt, but radiation readings in the water and air at Fukushima have been steadily decreasing somewhat over the past week. 
Yesterday's readings are substantially improved over the numbers released last Saturday.  If accurate, these readings are excellent news- it's about time.
