Introduction to Internal Dosimetry

In this chapter, we will learn about internal dosimetry, which is the measurement of radioactive contaminant present inside human body. First, we will discuss basic idea about the field on internal dosimetry. Then, there is a brief introduction on various exposure scenarios and routes of internal contamination. We will also have a short discussion on biokinetic and dosimetric models used for internal dosimetry. Some special quantities used only for internal dosimetry are also defined in this chapter. Next, we discuss the need for internal dose assessment. Various types of internal dose monitoring are also covered. The equipments used for workplace and personal monitoring are introduced. Decorporation, of excess radioactivity in accidental cases is also covered. Finally, dose estimation and standards used in internal dosimetry are covered.
