“…For this purpose, acquiring experimental data following the method employed here would be very difficult and tedious. Calculating the detector response with Monte Carlo methods was found to be reliable for welldefined experimental situations (Lamart et al, 2009;Lopez et al, 2011;Broggio et al, 2012). However, in the present case a very detailed model of the MUs would be necessary because of the significance of scattered radiation.…”

-The measurement performances of in vivo monitoring vehicles were studied considering an increase in the radiological background in areas where the population is not evacuated after a nuclear accident. The study focused on 137 Cs and 131 I Detection Limits (DLs) and corresponding doses, for adults and one-year-old children. These DLs for ground contamination were obtained experimentally using a grid of point sources. Then, the DLs and doses were calculated using the experimental data and a safety factor for two accident scenarios. For these scenarios the 137 Cs DL corresponds to a committed effective dose of 0.02 mSv. The 131 I DL corresponds to committed equivalent thyroid doses of 3 mSv (adult) and 30 mSv (one-year-old child). To guarantee a 45 mSv thyroid equivalent dose assessment for the child the surface activity of 131 I + 132 I + 133 I should be below 1.6 MBq/m 2 . This study shows that the vehicles can operate in a contaminated area where the population is not evacuated. However, in such a case, the contamination level outside and inside the vehicle should be kept stable to guarantee efficient body counting.

“…This range is within a generally accepted uncertainty range for such kind of measurement. Only one result in task 2B (for participant P02), reported a large (Broggio et al, 2012). It indicates that building the mathematical model of the real detector, for the purpose of performing MC phantom calibrations, is not a large source of uncertainty.…”

“…The dissemination of knowledge and training in internal dosimetry is one of the main goals of Working Group 7. In collaboration with Working Group 6 (Computational Dosimetry), several intercomparison exercises on the application of Monte Carlo methods for the efficiency calibration of in-vivo counters have been undertaken (Gómez-Ros et al., 2008; Lopez et al., 2011b; Broggio et al., 2012; Vrba et al., 2014). In 2017, an intercomparison exercise with case studies for dose assessments has been organized.…”

European Radiation Dosimetry Group (EURADOS) Working Group 7 is a network on internal dosimetry that brings together researchers from more than 60 institutions in 21 countries. The work of the group is organised into task groups that focus on different aspects, such as development and implementation of biokinetic models (e.g. for diethylenetriamine penta-acetic acid decorporation therapy), individual monitoring and the dose assessment process, Monte Carlo simulations for internal dosimetry, uncertainties in internal dosimetry, and internal microdosimetry. Several intercomparison exercises and training courses have been organised. The IDEAS guidelines, which describe - based on the International Commission on Radiological Protection's (ICRP) biokinetic models and dose coefficients - a structured approach to the assessment of internal doses from monitoring data, are maintained and updated by the group. In addition, Technical Recommendations for Monitoring Individuals for Occupational Intakes of Radionuclides have been elaborated on behalf of the European Commission, DG-ENER (TECHREC Project, 2014-2016, coordinated by EURADOS). Quality assurance of the ICRP biokinetic models by calculation of retention and excretion functions for different scenarios has been performed and feedback was provided to ICRP. An uncertainty study of the recent caesium biokinetic model quantified the overall uncertainties, and identified the sensitive parameters of the model. A report with guidance on the application of ICRP biokinetic models and dose coefficients is being drafted at present. These and other examples of the group's activities, which complement the work of ICRP, are presented.
