A new method for tooth (enamel and dentine) and bone EPR dosimetry is proposed that enhances substantially the dosimetric sensitivity. The method is based on the nonstandard spectra registration mode (the second harmonic phase quadrature detection of absorption under rapid passage conditions). This method provides an apparent enhancement of the component ratio of radiation to a nonradiative bac...

Passive solid state dosimeters, such as thermoluminescence provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective this paper is to a comprehensive review on use thermoluminescent dosimetry methods for radiation environment. article presents part research results project PREPAREDNESS (EMPIR 2016 call Metrology Environment joint pr...

The thermoluminescence (TL) properties of laboratory grown quartz have been studied for its possible high gamma dosimetric applications. The variation of 210 o C glow peak is observed in different annealed samples followed by gamma irradiation near room temperature. The peak was found very sensitive to the pre-thermal treatments. The radiation induced effects in quartz have been studied in deta...

Alkali feldspars are routinely used in retrospective dosimetry using luminescence methods. However there is a signal loss over time, termed ‘anomalous fading’, which results age underestimation if uncorrected. Although significant improvements have been made recent years, dating of remains challenging. This paper investigates the relationships between chemistry, structural state and scale exsol...

This work presents an extensive study on Monte Carlo radiation transport simulation and thermoluminescent (TL) dosimetry for characterising mixed radiation fields (neutrons and photons) occurring in nuclear reactors. The feasibility of these methods is investigated for radiation fields at various locations of the Portuguese Research Reactor (RPI). The performance of the approaches developed in ...
