28. 在除心血管病和癌症以外所有其他疾病组的死亡率方面，关于其与剂量低于约 1-2 Gy 的辐射照射之间存在关联的证据也是仅仅来自对原子弹爆炸幸存者数据的分析。其他研究在推断与剂量低于约 1-2 Gy 的辐射照射之间存在因果关系方面所提供的科学证据甚至比有关这些人口心血管病的科学证据还要少。其中的部分原因是由于数据有限，疾病的异质性较大，存在各种病理机制和病因，以及混杂因素较多等。
28. For mortality from the group of all diseases apart from cardiovascular disease and cancer, the evidence for an association with radiation exposure at doses of less than about 1-2 Gy is also only derived from the analysis of the atomic bombing survivor data. Scientific evidence from other studies for inferring a causal relationship with radiation exposure for doses of less than about 1-2 Gy is even less sufficient than that for cardiovascular disease in these populations. This is in part because of limited data, the large heterogeneity of diseases and the various pathological mechanisms and aetiologies, as well as a multitude of confounding factors.
