RESULTS OF WBC MEASUREMENTS WERE MADE AT RADIOACTIVELY CONTAMINATED TERRITORIES OF UKRAINE IN 1986–2014 (REVISION AND ANALYSIS)

Objective: revision, analysis, and significant improvement of quality of the database of WBC measurements made in 1986–2014 at radioactively contaminated territories of Ukraine by the use of renewal of informational gaps and improvement of the model for assessment of internal exposure doses. Materials and methods. Inthe periodfrom 1986 to 2014 experts of the Whole Body Counters Laboratory of NRCRM accumulated about 1.5 million results of WBC measurementsof radio cesium incorporated in the body of persons residing at the territories which are radioactively contaminated due to Chornobyl accident. Most of measurements (~ 64%) were made during the first 15 years after the accident. The most of measurements were made in Kyiv (~ 23%), Zhytomyr (~ 36%), Rivne (~ 20%) and Chernihiv (~ 5%) Oblasts. Works on revision of database of WBC measurements included: transformation of data saved in paper format into electronic form, checking for correctness and correspon dence of information, renewal of lacking information at the fields of database, improvement of the model for eva luation of internal exposure doses by the data of WBC measurements. In the model for evaluation of revised doses, it is assumed uniform content of radio cesium during a year. Reference values are used of metabolism parameters and anthropometric human parameters recommended in publications of ICRP. Results. Revised doses have been reconstructed for 1,386,585 records of data …
