Abstract: In 2002, an extensive study was performed in forest sites of Izmir. This first study results led on the one hand, to quantify of ¹³⁷Cs and ⁴⁰K concentration in mushrooms collected in the Izmir region and to a first evaluation of dose in people due to the ingestion of radionuclide-contaminated mushrooms. The mushroom concentration values varied over a wide range from below detection limit to 401 ± 4 Bq kg⁻¹ (dry wt) for ¹³⁷Cs. The ⁴⁰K concentration values obtained for different species of mushrooms ranged from 588 ± 26 Bq kg⁻¹ to 2024 ± 63 Bq kg⁻¹ (dry wt). The annual effective dose values due to mushroom ingestion for ¹³⁷Cs are lower than the ICRP-2007’s reference level value of 1 mSv for “existing” exposure situation. Inductively coupled plasma-mass spectrometry was used to measure many alkali–alkaline earth elements and heavy metals in mushroom samples. The relationships among the concentrations of ¹³⁷Cs and the stable elements were presented and the occurrence of metals in mushrooms was evaluated.

Abstract: The aim of the thesis: Application of the results of WBC (whole body counter) measurements of the activity of 137Cs verification tool for the calculation method of the assessment of individual internal doses of total body irradiation in the population at the radioactively contaminated areas of Bryansk region, based on the use of radio-ecological model and the primary information contained in the individual dosimetry questionnaires.
