This was in our local paper. Radiation by the numbers


Unfortunately, the distinction between mSv and mSv/hr isn't really explained but...

With respect to Message 1 of March 16, the majority of the public has no idea what a 'sievert' is much less confusing micro and milli.  Few of the news items I have seen put the dosage information in context to 'normal background' or 'action levels' or health affecting levels along with the accompanying exposure times.  No wonder there is so much fear - the  explanations should be in simpler, layman language. As for the discussion  mentioned by Roger, where was that discussion?

Unfortunately the Public and news people mistake  milli and micro for thousand and million respectively.

There was good explanation just on about difference between milli  and microSieverts and showing comparable doses in addition to the  radiation measurements at various distances from  Fukushima
