项目摘要

In neutron beam exposure accident by nuclear fuel disposing facility (JCO) of the Ibaraki Prefecture Tokai village which was generated in September, 1999, the treatment of the indoor standby was done to resident with a radius of less than 10 km by the administration. There is no radiation exposure which has influence on a human body in fact, our study was done in order to scientifically clarify the condition of the stress disorder of the residents who received refuge advice, and who set in the indoor standby state. The last fiscal year, it planed to investigate centering on the accident spot of JCO by General Health Questionnaire (GHQ). 80 households of random sampling for the residents who reside in the radius of 500m or more, and less than 1000m were investigated. We got 102 persons' (49 men, 53 women) reply. This fiscal year, GHQ investigation was done on 50 households of random sampling for the residents in the radius of 1km or more, and less than 2km centering on the accident spot of JCO. We got 74 persons' (36 men, 38 women) reply.We used the questionnaire of the GHQ60. The investigation using GHQ12, GHQ20, GHQ28, GHQ30, etc. was reported in the literature. Thirty-three percent short-distance resident and 22% long-distant resident were abnormal person with three or more points by using GHQ12. By using GHQ20, the abnormal persons with five or more points were about 28% and about 28%, respectively. By using GHQ28, the abnormal persons with seven or more points were about 29% and about 21%, respectively. By using GHQ30, the abnormal persons with seven or more points were about 22% and about 22%, respectively. By using GHQ60, the abnormal persons with 17 or more points were about 22% and about 23%, respectively. There is almost no difference by the sex.

1999年9月，茨木县东海村核燃料处置设施（JCO）发生中子束照射事故，管理部门对半径10公里以内的居民进行了室内备用处理。实际上，没有对人体有影响的辐射照射，我们的研究是为了科学地澄清接受避难建议的居民的应激障碍状况，以及进入室内待命状态的居民。上一财年，计划以JCO事故现场为中心，采用一般健康问卷（GHQ）进行调查。随机抽取居住半径在500 m以上和1000 m以下的居民80户进行调查。我们收到了102人（49名男性，53名女性）的答复。本财年，GHQ对以JCO事故现场为中心半径1公里以上、2公里以内的居民随机抽样50户进行了调查。采用GHQ 60问卷，共获得74人（男36人，女38人）的回答。文献中报道了使用GHQ 12、GHQ 20、GHQ 28、GHQ 30等的研究。33%的近距离居民和22%的远距离居民在GHQ 12量表上有3分或3分以上的异常。用GHQ 20量表测得5分及以上的异常者分别约占28%和28%。用GHQ 28量表测得7分及以上的异常者分别约占29%和21%。用GHQ 30量表测得7分及以上的异常者分别约占22%和22%。使用GHQ 60，17分及以上的异常者分别约为22%和约23%。几乎没有性别差异。
