I would certainly want any activity in that area to be by trained adults who carry and regularly check radiation monitors and do not live anywhere close. It is hard enough to get adults to take proper precautions so the general area should certainly be a no go area for children. And, again, any effects are cumulative, so the time spent on site is important. Doing construction could involve relatively limited amounts of time for individual workers and routine maintenance could require even less. And most of the area is well above the height reached by the tsunami, so solar thermal and/or solar panels, if properly sited, should be ok.
