内照监测的重要性是十分显然的。一般来讲,内照监测也比外照监测复杂得多。目前采用的内照监测方法主要有两种:以尿样分析为主的生物样品分析法和以全身计数器为主的直接测量法。前者的主要优点是设备简单、费用低、灵敏度高。缺点是不能推断主要积聚器官、且操作费时费事。全身计数器虽有不能区分体内污染与外部沾污,且设备复杂、费用高等缺点;但它具有直接、快速、灵敏、误差小、使用方便等优点。因此,各种类型的全身计数器得到了迅速发展。
The importance of internal monitoring is clear. In general, internal monitoring is also much more complicated than external monitoring. There are two main methods of internal monitoring currently used: the biological sample analysis method mainly based on the urine sample analysis, and the direct measurement method based on the whole body counter. The former has the main advantage of simple equipment, low cost and high sensitivity. The disadvantage is that you can not infer the main accumulation of organs, and the operation is time-consuming and cumbersome. Although the body counter can not distinguish between internal pollution and external contamination, and the complexity of the device, high cost shortcomings; but it has a direct, fast, sensitive, error is small, easy to use and so on. As a result, various types of whole body counters have been rapidly developed.
