The content consists mainly of 'Situations at the time of explosion', 'Mind', 'Body' and 'Life'. Statistical analyses were carried out to examine backgrounds that effected on the degree of anxieties about atomic-bomb survivors'/their offspring's health condition. Mother's death due to the bombing or an experience of social discrimination increased anxieties for their health condition in addition to have had acute symptoms due to the bombing or atomic-bomb diseases.
