摘要
目的对红沿河核电站运行前瓦房店市居民恶性肿瘤死亡情况进行基线调查，为核电站的正常运行及核事故对健康影响的评价提供科学依据。方法瓦房店市30个乡镇按照距离核电站0、10、20、30和40kmt外分成5个调查区域进行分析，分析不同区域、不同性别、不同年龄恶性肿瘤的死亡分布。选取对辐射敏感的恶性肿瘤（白血病、乳腺癌和甲状腺癌）的死亡资料进行分析。结果瓦房店市2006-2009年恶性肿瘤死亡率为151．97／10^5（标化率97.76／10^5），男性死亡率为188.28／10^5（标化率116.76／10^5），女性死亡率为113．47／10^5（标化率75.89／10^5），性别比值为1.71。恶性肿瘤死亡顺位前5位为肺癌、肝癌、胃癌、结直肠癌和食管癌；死亡率依次为46.19／10^5、23．51／10’、20．30／10’、8．06／10’和5．45／10’；距离核电站由近及远的区域恶性肿瘤死亡率分别为：99.85／10^5、137.40／10^5、138.73／10^5、156.30／10^5和154.16／10^5。与核辐射相关的恶性肿瘤，白血病、乳腺癌和甲状腺癌的死亡率分别为4.57／10^5、4.06／10^5和0.26／10^5。结论核电站运行前，该地区恶性肿瘤的死亡以肺癌和消化道恶性肿瘤为主。不同区域、不同性别恶性肿瘤死亡构成无差别；不同区域、不同年龄组恶性肿瘤死亡构成无差别；不同区域和不同性别、不同年龄组白血病死亡构成均无差别；不同区域、不同年龄组乳腺癌死亡构成无差别。
Objective To understand the baseline data of mortality from malignant tumor from 2006 to 2009 around Hongyanhe Nuclear Power Plant in Wafangdian City, Liaoning Province, so as to provide scientific basis for evaluating the impact of normal operation of nuclear power plant on the health of the residents nearby. Methods Thirty small towns near Hongyanhe Nuclear Power Plant were divided into 5 investigated areas according to the distances away therefrom （0-, 10-, 20-, 30-, and 40-km）. The data about from malignant tumor were obtained from the Center for Disease Control and Prevention of Wafangdian. The mortality distribution of different malignant tumors was analyzed, including the radiosensitive malignant tumors, especially leukemia, breast cancer, and thyroid gland cancer in different area, gender, and age groups. Results The mortality from malignant tumor was 151.97/105, and the standardized mortality rate （SMR） was 97.76/10s. The mortality from malignant tumor among the males was 188.28/105（ with the SMR of 116.76/105）, and that among the females was 113.47/105（ with the SMR of 75.89/105 ） , with a sex ratio of 1.71. The first five cancers in the rank of death causes were lung, liver, stomach, colorectal, and esophageal cancers with mortality of 46. 19/105, 23.51/105, 20.30/10^5, 8.06/10^5 and 5.45/10^5 , respectively. The mortality from malignant tumor in the areas around the nuclearpower plant from tile near to the distant were 99.85/10^5 , 137.40/10^5 , 138.73/10^5 , 156.30/10^5 , and 154.16/10^5 ,respectively. The mortality from radiosensitive malignant tumors, leukemia, breast cancer, and thyroid gland cancer were 4. 57/10^5 , 4.06/10^5 , and 0. 26/10^5 , respectively. Conehtsions Lung cancer and digestive tract malignant tumors are tile main causes of death from malignant tumors in Wafangdian area before the nuclear power plant began to operate. There are no significant differences in the mortality distribution of malignant tumors among different areas, genders, and age groups. There are no
