A self-administered questionnaire survey conducted in 52 years
after the atomic bombing revealed that atomic bomb exposure
conditions, experiences at the time of bombing, current lifestyle
factors and current living conditions have affected survivors' mental health. The frequency of subjects with a high GHQ-12
(12-item version of the General Health Questionnaire) score was
higher in those exposed within 2 km of the hypocenter (10.6%)
than in those exposed at 2.1 to 3 km from the hypocenter (9.4%)
and those exposed 3.1 km or further from the hypocenter (7.2%).
