Dosimetry: The Art of Measuring the Energy Deposited by Ionizing Radiation in a Medium

摘要

We present a brief overview of ideas related to dosimetry, its principles, and its practice. Cavity theories and the need for careful interpretation of dosimetric measurements are introduced. Ionization chambers, TLDs and radiochromic films are described, as well as the accuracy requirements for dosimetry in radiotherapy and diagnostic radiology.
