Retrospective dose assessment to the built environment is but one example of environmental dosimetry – the assessment of dose to the environment and/or air. Another example, which is also a type of retrospective dosimetry, is measurement of the natural background dose as part of geological or archaeological dating. Here, an assessment of the dose rate in the soil of a sedimentary layer and the assessment of dose to the artefact found in that layer enables an estimate of the time the artefact has been buried (i.e., the age). Other examples might be the assessment of dose in the air or the soil surrounding a radioactive waste storage site where regular environmental dose assessments of the area surrounding the site are required for monitoring of waste leakage. A final example is the monitoring of doses in air surrounding a nuclear power plant. In each of these applications, both TL and OSL have found application and their use continues in this way.
