The media loves to abuse the deliciously ambiguous term up to.
Why do some reporters like to get hold of a range of values from a scientist or engineer and then quote the number at the scariest end of the range?
Some media sources are reporting radiation levels of 1000 times normal following a problem with Japan's Fukushima Number One plant. Following the earthquake the pressure rose in a containment vessel.
The [Japanese Nuclear and Industrial Safety] agency says radiation levels have risen to up to about 100 times the normal figure in the central control room where the reactor's operators are working.
Since when does up to 100 translate into 1000 times?
Considering the margins of safety in the nuclear industry, up to 100 times normal is still not a scary, run-away-screaming scenario - although it is a matter for concern.

Earthquake and Tsunami Update
It seems the media will spin anything to make money.
World Media In Money-Making Plot, blogger claims.
... a monstrous earthquake like what they had can't be a light issue but at least we can keep opportunists from capitalizing on it and selling ridiculous 'end of the world' books.
