AbstractStrontium isotopes are a powerful tool which provide information about provenance directly from the tissues of humans rather than the grave context and burial goods.Geographical variation in strontium isotopes is primarily controlled by the underlying geology but there are many other factors that need to be considered before migratory individuals can be identified. Consequently, despite many studies which have shown that the method works well, it is clear that much remains to be clarified and it will not work for every question or in every place. It rests on the assumption that people were sourcing their food locally and that there is a measurable strontium isotope difference between the place the person migrated from and the place they migrated to. As migrants may deliberately seek out familiar soil types and terrains in their new homeland, some questions surrounding major migration events may prove intractable for this technique. Other factors that can create heterogeneity or homogeneity leading to false positives or false negatives, such as human choices or coastal subsistence, are explored and the metabolism of strontium into human tooth enamel is discussed.Several models of land use choices by humans are presented to highlight the subtleties inherent in the isotope data and these are used to interpret archaeological human isotope ratios from three studies.

“…Loss of minerals from tooth enamel is attributed mainly to ion diffusion and tooth surface reactions. Strontium elimination is likely to occur by the same processes as those affecting calcium elimination, i.e., diffusion, surface dissolution or demineralisation and mechanical attrition (Suga and Watabe, 1992 ;Tolstykh et al, 2003).…”

“…These factors make the volume-averaged dose provided by EPR measurements of little significance for short-range particles. Tolstykh et al (2000Tolstykh et al ( , 2003 argued against the suitability of EPR dosimetry with 90 Sr contaminated teeth, in particular because the estimate of the tooth enamel dose should account for the time dependence of the 90 Sr content and distribution not only in enamel, but also, and especially, in dentine. They concluded that EPR tooth enamel dosimetry should be limited to the assessment of the external dose component.…”

“…Long ago, Goldman et al (1967Goldman et al ( , 1972, who injected animals with radionuclides, found that 90 Sr content of a bone decreases significantly throughout the person's life because of bone remodelling, in contrast to the stable 90 Sr content of enamel. More recently, Tolstykh et al (2000Tolstykh et al ( , 2003 found that there is a complex correlation between radionuclide accumulation in teeth (both dentine and enamel) and in bone, which brought them to a conclusion that a conversion of a tooth dose to the bone dose requires complex models. They compared data obtained by radiochemical measurements of extracted permanent posterior teeth, in vivo measurements of surface β −activity of the anterior teeth, and whole-body (counter) measurements of 90 Sr in the skeleton.…”

Tolstykh et al (2000Tolstykh et al ( , 2003 have demonstrated that EPR dosimetry using tooth enamel can provide external doses to the residents along the Techa river if 90 Sr concentration in enamel is measured by independent methods (Goksu et al, 2002;Romanyukha et al, 2002b;Shishkina et al, 2005;Veronese et al, 2006).

When tooth enamel is exposed to ionizing radiation, radicals are formed that can be detected using Electron Paramagnetic Resonance (EPR) techniques. EPR dosimetry using tooth enamel is based on the (presumed) correlation between the intensity or amplitude of some of the radiation-induced signals with the dose absorbed in the enamel. In the present paper a critical review is given of this widely applied dosimetric method.The first part of the paper is quite fundamental and deals with the main properties of tooth enamel and several of its model systems (e.g., synthetic apatites). Considerable attention is also devoted to the numerous radiation-induced and native EPR signals, and the radicals responsible for them. The relevant EPR detection, identification and spectrum analysing methods are reviewed from a general point of view. Finally, the need for solid state modelling and the linearity of the dose response are investigated.The second part is devoted to the practical implementation of EPR dosimetry using enamel. It concerns the preparation of samples, specific irradiation problems, spectrum acquisition and it is described how the dosimetric signal intensity and dose can be retrieved from the EPR spectra. Special attention is paid to the energy dependence of the EPR response and to sources of uncertainties. Results of and problems encountered in international intercomparisons and epidemiological studies are also dealt with.In the final chapter the future of EPR dosimetry with tooth enamel is analysed.

This article focuses on the study of (90)Sr in the tooth tissues of Techa riverside residents 60 years after intake. The Techa River was contaminated by radioactive wastes in the 1950s. Contamination of the river system, including water, bottom sediment, floodplain soil, and grass, depended on the distance from the source of releases. Therefore, the average (90)Sr intake was different in different settlements located downstream the river. An additional factor influencing (90)Sr accumulation in the teeth is the rate of tissue mineralization at the time of intake which depended on the donor's age at the time of releases. Measurements of (90)Sr concentration in various dental tissues (enamel, crown, and root dentin) of 166 teeth were performed about 60 years after the main intake using the method of thermoluminescence passive beta detection. The paper presents the current levels of tooth tissue contamination, and the tooth-to-tooth variability of (90)Sr concentration in tooth tissues was assessed for the tissues which were matured at the time of massive liquid radioactive waste releases into the Techa River. A model describing the expected levels of (90)Sr in matured dental tissues depending on age and intake has been elaborated for the population under study. The results obtained will be used for calculation of internal dose in enamel and for interpretation of tooth doses measured by means of the electron paramagnetic resonance method, among the population of the Techa River region.
