The population of Slovenia, like populations elsewhere in the world, is exposed to natural ionizing radiation as well as to certain anthropogenic sources of ionizing radiation, which come primarily from the use of ionizing radiation sources in medicine, the residual Chernobyl contamination and the contamination generated by atmospheric nuclear tests. When it comes to the residents in the surroundings of the Krško Nuclear Power Plant (Krško NPP), we could add the discharges of atmospheric and liquid radioactive substances from the Krško NPP and the direct radiation emanating from the buildings and objects inside the power plant's fenced perimeter.

The Krško NPP is required to comply with authorised limits and other dose limits related to releases, as well as other radiation impacts on the environment and population. The Krško NPP is required to provide evidence of compliance by performing operational off-site environmental radioactivity monitoring (ERM), the scope and method of which are prescribed by the Rules on the monitoring of radioactivity.

The ERM includes measurements of emissions on the premises (source term), measurements of imissions in the surroundings, measurements of external radiation in the environment, evaluation of measurement results and the dose assessment.

The ERM includes measurements of emissions at the facility, measurements of immissions in the environment, measurements of external radiation in the environment, evaluation of measurement results and dose assessment.

Apart from the Krško NPP, which is in charge of emission measurements, the ERM is performed by various authorised monitoring providers.
