center in western Namie in the belief that seasonal winds would blow radiation from the plant in a different direction. However, a change in wind direction blew the plant's plume directly at them, heavily contaminating that part of the town. It was revealed months later that the national and prefectural governments had known about the direction of the plume due to forecasts by the SPEEDI computer system, but had decided not to tell evacuees in order to prevent a panic. Tamotsu Baba, Namie's mayor at the time, said the decision to withhold information from his town was akin to "murder." On 15 April 2012, the town of Namie asked the Japanese government for free health-care for its residents. To monitor the long-term health, the city would provide to all inhabitants health handbooks in order to keep a thorough record of all health checks and thyroid examinations. The health books were made like the books used to monitor the health of the atomic bomb survivors in Hiroshima and Nagasaki. These "hibakusha" health books were free from medical fees, and Namie asked the government to set up a similar program for the people in Namie. Of the seven other cities around the nuclear plant, Futaba town was also willing to take part in this program. In April 2012, the government of the evacuated town of Namie bought a whole-body dosimeter. The device was installed in a temporary housing in Nihonmatsu, Fukushima, in order to monitor the internal radiation exposure and the health of the citizens of Namie. Some 50 people a day could be examined, a complete screening would take two minutes per person. Initial screenings of the whole population was planned to be finished at the end of the fiscal year 2012. In this way the town government wanted to offer a long-term monitoring program to the population. Another reason for this was the excessive exposure to radiation during the first days directly after the nuclear disaster in March 2011, when predictions from SPEEDI were ignored by the Fukushima Prefectural government. On April 1, 2013, the nuclear evacuation zone in Namie was revised. Japanese authorities set three different zones according to different levels of radiation: in the first, people were free to go in and out, but not allowed to stay overnight; in the second, access was limited to short visits; and in the third area, all entry was forbidden because
