Abstract
Radiation dosimetry is the science of determining the fraction of the energy which is absorbed in matter during interaction with ionizing radiation [5]. Due to the fact that children are much more sensitive to ionizing radiation than adults, radiation dosimetry may be considered as one of the most important topics in paediatric radiology. In this chapter, the fundamentals of radiation dosimetry against the background of paediatric radiology will be presented. Therefore, the description of radiation physics will be focus on clinical paediatric aspects. For a more physical description, see e.g. [1, 5, 14, 18, 54].

The exponential attenuation law is due to the fact that the photo, Compton, and pair formation effects are stochastic effects occurring with a probability being proportional to the irradiated volume.
