Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
For location dependence, check this map of Germany. The association with certain mountains is obvious.

The Japanese chart assumes you are getting several times this from various--friendly! ;)--sources, but still it is the same order of magnitude.  

The German map is pretty well centered on one mS/yr.  

Since there is no safe level of radiation exposure (well, the universe just isn't a safe place, you know?--or rather, literally, radiation damage has no threshold.)  this is one end of your risk yardstick.  At the other end lies short exposures (within a few days) of 1000 mS (likely radiation sickness) or 6000 mS (LD50, even with medical treatment).  

In the middle:  At radiation levels below 10 mS/yr cancer rates tend to drop into the noise of cancers due to earth background, above that level they become statistically measurable.  

The Fates are kind.
