Contents of major radionuclides (cesium and cobalt) in the water that is thrown into the river Styr after use at the Rivne nuclear power plant range between 0.278-0.018 percent of the standards established by the regulations of radiation safety in Ukraine (NRSU-97). These figures, confirming safe operation, have been obtained by specialists of the automated radiation control system, which is involved in the effort to protect the environment.

As UKRINFORM reported, through the creation of this structure, which has fixed and mobile positions in the thirty-kilometer surveillance zone, environment monitoring by all the IAEA-defined parameters is conducted there.

Specialists using modern computerized equipment are measuring doses of aerosol emissions, controlling aquifers (through artesian wells), exploring plant production and milk, etc.

Earth samples have also been taken to show that in some places there is a slight increase in Cesium-137, but it is of Chernobyl origin, which is indicated by its man-made nature.

The automated radiation control system covers an area of three thousand square kilometers with a population of 130,000 in 90 settlements of Rivne and Volyn regions.

With the commissioning of the station, it became possible, inter alia, to 'weigh' the volumes of long-lived isotope tritium. Until recently, such a laboratory procedure was performed only at nuclear power plants of Canada, although the system of fixing this element is established at all nuclear power plants around the world. It is important for safe operation, because, as experts say, the value of tritium presence is one of the most fundamental in assessing the interaction of the nuclear power plant with the environment. Introduction of the element catching methods came as a response to the IAEA recommendations on the evaluation and registration of actual emissions, which are normalized by the Ministry of Health.

Another important component is a weather complex, which serves for the remote sensing of the atmosphere at an altitude of three kilometers, and determines the speed, direction of horizontal and vertical wind, atmospheric stability category, and air temperature.

The concept of effective environmental management implemented at Rivne was approved after an audit by an independent expert organization, TUV NORD (Germany), which issued a relevant certificate.
