Passive dosimetry is a well recognized methodology for radiation dosimetry. In the framework of passive radiation detectors the whole inorganic nature of terrestrial and extraterrestrial origin is, potentially, a huge passive dosimeter. This fact lead to the growth of methodologies. which use natural materials as radiation dosimeters in order to evaluate the radiation doses released in the environment due to both natural sources and to man made radiation facilities and sources. In this presentation some of these methodologies will be described. Furthermore, the theoretical and experimental research required in order to transform a natural material to a radiation dosimeter in action is discussed.
