It seems you are right about hospital evacuations. From 2012, "A hospital [Futaba Hospital] near the disaster-stricken Fukushima No. 1 nuclear plant made no mistakes during a hasty evacuation in March 2011 during which 40 patients and nursing home residents lost their lives, according to a report released on Sept. 30 by investigators commissioned by the hospital." Unfortunately, that hospital is within 3km of the reactor and was evacuated between March 12th and March 16th. It's also worth noting that the radiation level on the day of the disaster, March 11, was 1,590 uSv/hr at a point 5km away (normal background radiation for a city is 0.25 uSv/hr). This is, per hour, more radiation than background exposure for a year in most cities. Fukushima Prefecture is the third largest prefecture in Japan, and most of its largest cities emerged from the disaster with minor earthquake damage. Also, luckily, the area around the reactor is made up of small towns and villages, so I would like to believe the community's support has aided most of the refugees, but obviously it was a hardship.
