| Research Abstract |
The purpose of this study is to explore the effects of radiation exposure on the inhabitants near the Semipalatinsk Nuclear Test Site (SNTS) established on the basis of a questionnaire survey and their testimonies. For this purpose, we conducted the field research and examined the results of our questionnaire surveys from 2002 to 2005 in terms of a statistical method Sled logistic multiple linear regression analysis.
1. Our questionnaire surveys were conducted two times from 2006 to 2007 in nine villages near the SNTS. The total number of replies was 475 and that of testimonies was 396.
2. We finished feeding all the Hiroshima and Nagasaki testimonies of the Asahi Shimbun in 2005 into a computer in order to compare with those of the Semepalatinsk area.
3. Approximately 94 % of respondents experienced something directly from the nuclear tests.
4. Approximately 66 % of respondents answered that they saw the flash of the nuclear explosions, 50 % of respondents answered that they felt the bomb blast and only 12 % of respondents answered that they felt heat.
5. Their direct experiences from the nuclear explosions is dependent not on radiation exposure level but on the distance from the hypocenter at the SNTS.
6. 31% of the residents reported that they felt bad or were in very poor health.
7. Residents living in villages having higher radiation levels were more likely to report having poor or very poor health, minor complaints such as loss of sleep, headaches, nighttime sweating and swollen arms or legs, and the need for nursing care in performing activities of daily living.
8. Radiation exposure in the Semipalatinsk area is one of the causes of poor health in general among residents. There is also a possibility that radiation exposure influences the incidence of some specific medical conditions.
