I'm guessing 161 uSv/h is a local maximum, and that over the course of the upcoming year, that number is expected to dramatically fall. I suggest multiplying 161 uSv/h by 24h to see the daily effect: 3.86 mSv/day. That's not too bad, as long as it starts dropping.

This would be 1408 mSv/year. In Germany it is requested that people have to leave areas with radiation above 100mSv/year for at least a year.

No doubt the 161 uSv/h figure will drop as the plant becomes more contained, and it's unlikely sticking around for a full year will net you the full 1400 mSv. That being said, right now we're looking at 3.86 mSv/d, which in and of itself is not a number to scoff at, and is well above dose limits, conservative as they are. This is considerably different than when people were panicking over 50 uSv/d. When you are in an area that exceeds the yearly dose limit in a single day, it seems like evacuation is prudent. The fact that the government hasn't widened the evacuation area despite rising ambient radiation is concerning.

  The radiation levels are getting a lot of public scrutiny - because the information is public. I don't see how this compares to a Chernobyl-style government coverup.

    The numbers are IAEA numbers - not released by TEPCO or the Japanese government. Certainly this isn't on the order of a Soviet-era coverup, but from the appearance right now information is as open as it perhaps ought to be, and preventative/remedial action not as aggressive as might be justified. It's hard to say in this giant void of information, which is why I wonder how this will be viewed in time.
