| 6. | This risk factor table roughly shows the relationship between radiation doses and its effects on human body . it should be note that experimental data for dose - effect relationship are still scanty , especially for low doses and low dose rates
到目前为止，有关辐射效应与剂量的关系的资料还是非常贫乏，尤其缺乏人群在小剂量及低剂量率时的资料。 |
| 7. | It should be note that experimental data for dose - effect relationship are still scanty , especially for low doses and low dose rates . the risk factors are deduced from a single exposure of more than 1 gy and are subject to certain uncertainties . the figures are therefore neither precise nor final
因此危险度分析是推测性的，所根据的数据和资料主要来源于一戈以上单次照射的结果，而且有一定的不确定性，所以在应用时要留意其局限性，不能视其为精确的或不变的数据。 |
