Spatially resolved luminescence Single grain dating for mixed sediments or heterogenous radiation fields Not every grain in a sediment sample reflects the same last bleaching and burial history. By analysing single mineral entities (whether grains or parts of it) different dose populations can be distinguished and models derived for different events of e.g. beaching or deposition.

Food Irradiation Control using TL and PSL/OSL techniques European standards DIN EN 13751 | DIN EN 1788 Food stuff often is irradiated with ionizing radiation for sterilisation purposes. This requires the detection and estimates of the applied doses. The attached mineral dust or the food itself serves as dosimeter. TL/OSL to detect irradiation of e.g. spices Presence/absence of signal specific features shows the irradiation Dose estimates are possible for some materials Jo, Y., Sanyal, B., Chung, N., Lee, H.-G., Park, Y., Park, H.-J., and Kwon, J.-H.

Medical dosimetry Radiotherapy, diagnostic radiology, nuclear medicine Medical dosimetry Ionizing radiation from a large variety of isotopic sources, as well as accelerators, electron beams, etc. are increasingly used in radiotherapy. Clinical diagnostics employing ionizing radiation (mainly X-ray) is expanding. Such uses require monitoring of exposures as well as determination of the delivered doses which can be achieved by luminescence dosimetry.

Luminescence spectroscopy To investigate the luminescence properties of materials. Luminescence spectroscopy is used to investigate the luminescence properties of materials and thus allow more precise definitions e.g. of measurement parameters (e.g. detection ranges). It can help to better define the involved traps and centres, and contributes to the understanding of luminescence processes.

Spatially resolved luminescence Spatial differentiation of luminescence signals for mineral specific analysis and hot spot identification Measuring luminescence with EMCCD camera allows for the spatial differentiation of luminescence signals . Different minerals, mineral phases, radiation hot spots etc. can be determined in granular or solid samples and provide information on small scale differences of the radiation fields, or the material inhomogeneities (e.g. semiconductors).

Electron Spin Resonance A standard for many dosimetric application. Electron Spin Resonance (ESR/EPR) is an important tool for fundamental studies in many fields. Radicals are studied with ESR in life sciences, environmental chemistry, research in food safety/quality, the petrochemistry, bioinorganic chemistry and many more, together with studies on metal compounds, antioxides, etc. ESR is the standard for many dosimetric application in e.g. electron beam and neutron dosimetry of alanine tablets to determine irradiation doses. Solid state physics applications include the investigation of paramagnetic centers and their orientation within a crystal.
