That's certainly one of the better updates that I've seen.

Here's a quote from this report about radiation conditions for the emergency workers, noting the extreme conditions in Unit 3:

"To cope, the plant's operator, Tokyo Electric, has downgraded safety baselines both for the workers and the surrounding environment.

With the approval of the Japanese government, it has increased the permissible radiation exposure level for the Fukushima workers from 50 millisieverts a year to 250. This raises the risk of cancer by about 1.25 percentage points above the population average.

Yet even working in short shifts at this increased level, the radioactivity is so high in some areas, such as the No 3 reactor, that plant managers say humans may never enter again.(emphasis added)"
