The use of X-rays for diagnosis has been significant since its discovery. A measurement of the X-ray dose is the main determinant for risk vs benefit of these examinations. Radiation detectors are important for dose measurement. A description of these detectors, including the most frequently used ionization chamber, aids in the understanding necessary for their use. Proper and accurate use of detectors depends on an understanding of their calibration and their characteristics. Detectors such as ionization chamber, including specialized chambers, and solid detectors, including luminescent detectors, are described. This is followed by a description of the calibration process. The precision of measurements can be greatly affected by an understanding of the detector in use.
自X射线被发现以来，其在诊断中的应用意义重大。X射线剂量的测量是这些检查风险与益处的主要决定因素。辐射探测器对于剂量测量很重要。对这些探测器的描述，包括最常用的电离室，有助于理解其使用所需的知识。探测器的正确和准确使用取决于对其校准和特性的了解。文中描述了诸如电离室（包括专用室）和固体探测器（包括发光探测器）等探测器。接下来是对校准过程的描述。对所用探测器的了解会极大地影响测量的精度。
