The physics and physiology of radiation exposure seem to be quite complicated. I can't really answer your question, I'm very far from qualified to do so, but again _according to Wikipedia_ the short term effect of 0.2 Sv per day, let alone a year, seems to fall into the "no effect" category[1]. And according to this[2] post on Boingboing, the long term effect may not be as bad as one might think either.
The effects listed in the Wikipedia article refer to acute radioation poisoning, i.e. what happens when radiation is so intense that it directly kills so many of your cells that your body can't cope.
Even if at 0.2 Sv/d none of that happens, you still have a very actual, massively increased risk of cancer and genetic defects in future children. To declare "no health issues", you most definitely want to stay several orders of magnitude below that
