French-German Initiative – Project 3 – Health Sub-Project n° 3.9.1 Data Base on Radiological Situations, Countermeasures and Medical Care in Contaminated Settlements AUTHORS : Grebenkov A., Yakushau A., Mansoux H., Tirmarche M., Antsipov G., Averin V., Germenchuk M., Minenko V., & Zhouchenko Yu. RADIOLOGICAL PASSPORTS of Contaminated Settlements in Belarus: Database and Data Analysis

Objectives of the sub-project: 

Objectives of the sub-project Collection, securing and validation of existing data that cover radiological and sanitary information, and data on economical, demographic and societal infrastructure in selected settlements of Belarus Development of a database tool for risk-based decision-making protocol applied to inhabited areas Such the database would: Address critical locations (annual dose > 1 mSv) Assist for ranking of contaminated settlements and file data on these settlements to support a risk-based analysis Recommend and evaluate protection measures

Methodology: data collection: 

Methodology: data collection Radiological-Hygienic Passport (RHP) consisted of 13 separate forms grouped under three headings: Statistics (societal and demographic structure of population, housing, land used and predominant soil type) Economical infrastructure and public utilities (farms, industries, schools, hospitals, shops, service, etc.) Radiological data and doses (total area subdivided vs. level of contamination, 137Cs content in human body, contamination of agricultural products, contamination of households, annual effective dose) Every RHP is filled out by responsible organizations RHP is concluded with proposed countermeasures

Methodology: data verification: 

Methodology: data verification Statistics department of a higher-level Cross-references of different files Standard measurements followed by statistical analysis Additional revision along with the data of previous surveys Periodical spot checks or additional arbitral survey in case of significant deviation

Methodology: RHP Compilation:

Main results: 

Main results 96 settlements and data for the period from 1993 through 2001 Almost 15 thousand inhabitants in the areas with level of contamination ranging from 2.5 through 27.5 Ci/km2 Over 65 thousand samples of food products partitioning (seasonal, farming mode, etc.) effect of countermeasures About 1.5 thousand WBC measurements age occupation

RHP Database: 

RHP Database Realizes an informational block: data defining general parameters of a settlement; data on radioactive contamination (lands, buildings, food,…) ; demographic and societal parameters; industrial and municipal infrastructure, etc.; characteristics of available countermeasures. Realizes a simulation block comprised by the following models: contaminant transfer to basic forage resources and food; exposure and risk assessment and prediction; cost and efficiency analysis based on data of available countermeasures.

Conclusions: 

Conclusions RHP Database provides for target settlements: reliable data on radiological, sanitary and social parameters list and characteristics of appropriate countermeasures RHP Database provides for decision-makers a risk-based remedial planning tool a feasibility assessment of recommended measures based on a cost-benefit and least-cost analysis

Outlook: 

Outlook Further progress and use of RHP Database will facilitate wider recommendations concerning radiation, health, sanitary and social protection of contaminated settlements in Belarus, Russia and Ukraine The RHP Database user interface envisages populating the database with new information on continuing basis. Due to harmonized codes, it can be easy extended to Russian and/or Ukrainian regions
