“…Nevertheless, all-carbon detectors based on diamond samples [33] , [34] , [35] , with sputter-deposited or laser-induced graphitic contacts better fulfill the tissue equivalence requirement for radiotherapy dosimetry and would offer a valuable alternative to eliminate the possible spurious signals induced by secondary electrons emitted by metallic contacts [36] . Furthermore, we would like to emphasize that the implemented measurement method may mitigate the detrimental effects of non-linear conduction mechanisms induced by structural defects distributed within the active volume of the detectors [37] , as expected for laser-processed diamond samples [34] , [38] .…”

Passive dosimeters enabling accurate measurement of doses from gamma rays to visible light are necessary to ensure efficient utilization of electromagnetic radiation in numerous fields like medical diagnostics and industrial manufacturing. The specific requirements for dosimeters in terms of dosimetry range, sensitivity, accuracy, and stability for each application have led to the development of various dosimeters based on new materials and new mechanisms. Here, a comprehensive review of different types of dosimeters classified according to the response signal, namely electron paramagnetic resonance, electrical, and optical, is provided. This review starts with a general introduction to dosimetry, a classification of dosimeters, and an elucidation of the necessity of dosimeters in various ranges of the electromagnetic spectrum. This is followed by an overview of the fundamental requirements of dosimeters, an explanation of the general dosimetry procedure, and the dosimetric quantities. Emphasis is given to the working mechanism, the design concept, and applications of each type of dosimeter as well as their respective strengths and drawbacks. Challenges and prospects are presented at the end of the review. This review provides an insightful overview of the material‐mechanism‐characteristics‐application relationship of different types of dosimeters that hopefully can serve as inspiration for the development of new devices.
