| 公众对放射性作业场所是否安全提出质疑, 不仅反映了环保意识和自我保护意识的增强, 也反映了放射卫生监督监测不再仅仅是放射性作业单位和放射卫生监督管理部门的问题。虽然监测的内容及其方法近乎相同, 但监测的本质却发生了根本的变化。笔者报道了一例因居民对x射线探伤临时作业场所是否安全提出质疑而进行的一次放射卫生监测, 由此反映了临时在外探伤作业需要做某些必要的准备。一、场所概况 |

| Objective To estimate the excess relative risk for solid cancer associated with chronically exposure to high-background natural radiation in Yangjiang area of China. Methods Based on hamlet-specific environmental doses and sex-and age-specific occupancy factors, we calculated cumulative doses for each cohort member.Assuming a linear dose response relationship and using cancer mortality data for the period 1979-1995 and Poisson model, we estimated the excess relative risk(EER)for solid cancer. Results The ERR per Sv of all solid cancer is estimated to be -0.11(95% CI, -0.67, 0.69 to 95%).The corresponding figures for cancers of liver, nasopharynx, lungs and stomach are -0.99(-1.60, 0.10), 0.10(-1.21, 3.28), -0.68(-1.58, 1.66) and -0.27(-1.37, 2.69)respectively. Conclusion The association between ERR of solid cancer and dose can not be found. |
