Nuclear Medicine

核医学

There are a number of processes involved in health care that make use of the properties of the nucleus. Nuclear medicine is a broad term encompassing both diagnostic and therapeutic processes. To some extent this is unfortunate, since in the cases where nuclear radiation is involved the doses involved in diagnostic procedures are very small and those in therapeutic applications are very large. It is therefore important to make clear distinctions between the risks involved in diagnostic and therapeutic applications. Still another class of processes include diagnostic procedures such as magnetic resonance imaging which involve nuclear properties but do not involve any exposure to ionizing radiation.

医疗保健中涉及许多利用核性质的过程。核医学是一个涵盖诊断和治疗过程的广泛术语。在某种程度上这是不幸的，因为在涉及核辐射的情况下，诊断程序中的剂量非常小，而治疗应用中的剂量则非常大。因此，明确区分诊断和治疗应用中的风险非常重要。另一类过程包括磁共振成像等诊断程序，这些程序涉及核性质，但并不涉及任何接受电离辐射。
