The national remediation program in Croatia consists of three stages: (1) identification and characterization of radioactively contaminated sites; (2) preparing activities for restoration; and (3) physical restoration at selected (high-prioritized) sites. The program is coordinated by the APO and, in the first stage, performed by both national research institutes of Ruder Boskovi and Institute for Medical Research and Occupational Health. The program supervisors are Ministry of Health, Ministry of Economy (Department of Energy) and State Administration for Environmental Protection. There were more than thirty sites suspected to be radioactively contaminated in Croatia. They were classified into four contamination type groups: (1) dumps containing contaminated coal slag and ash; (2) dumps containing contaminated phosphates and phospho-gypsum resulting from fertilizers industry; (3) geothermal springs and gas/oil wells; and (4) sites containing ...

The uncertainties of growth in Croatian future energy, particularly electricity demand, together with growing environmental considerations and protection constraints, are such that Croatia needs to have flexibility to respond by having the option of expanding the nuclear sector. The paper deals with nuclear energy as an option for croatian sustainable economic development. The conclusion is that there is a necessity for extended use of nuclear energy in Croatia because most certainly nuclear energy can provide energy necessary to sustain progress. (author).

It is very difficult to compare environmental impacts of various electricity generation technologies and fuel types because they are extremely divergent. The most widely accepted common denominator today is the so-called external cost by which a monetary value is associated with environmental damage. In this paper, damages to human health resulting from Croatian thermal power plants annual operation are presented. Stack emissions have been translated into ambient concentrations by atmospheric dispersion modelling. Existing data on relations between human health degradation and ground concentrations of the analysed pollutants have been used. Geographic information software has been used in order to account for spatially dependent data. Monetary values have been assigned to the estimated human health damage. External costs resulting from impact of Croatian thermal power plants airborne emissions on human health have been calculated. The total Croatian thermal power system external costs, ...

After ten years' investigation of radon's seasonal variation at three very different locations, as well as radon concentration measurements in kindergartens, schools, air-raid shelters and cellars, systematic indoor radon measurements were undertaken in dwellings (residential buildings) of Osijek (East Croatia, 130andpuncsp; omitted000 citizens). Indoor radon was measured by means of the LR-115 SSNT detector at 48 town locations that gave an arithmetic mean of 71.6 Bq/m{sup 3}, standard deviation of 44.0 Bq/m{sup 3} and geometric mean of 60.1 Bq/m{sup 3}, for the radon concentration range from 22.7 to 185.6 Bq/m{sup 3}. Radon measurements, performed by the silicon Radhome detector, did not differ significantly. The empirical frequency distribution of radon concentrations, with the class width of 20 Bq/m{sup 3}, was in accordance with the theoretical log-normal distribution which was shown with the {chi}{sup 2}-test. The radon map pointed out a ...
