Aims and background: Mining and energy complexes in Serbia are recognized as a major source of a large number of pollutants. Serbia's environmental performance reports clearly indicate that large mining and energy complexes are the dominant source of air pollution. It is difficult to determine which of them remarkably threaten the quality of the environment, as all the basic elements of the environment (air, water, and soil) are threatened, not just one. Mining and energy complexes significantly reduce the quality of the immediate environment, as the distance areas throughout water and air pollution propagation. Additional motivation for this study lies in the fact that large mining and energy complexes are particularly interesting because they are located in the immediate vicinity or large rivers (mostly the Danube), which are protected in many national and international legislation acts (particularly the Danube). The basis for the preservation of environmental quality is an effective environmental management system (EMS) in mining and energy complexes. The aim of this study is to promote and elaborate the possibility for improving the mining and energy complex environmental protection/management system by applying the basic principles of sustainable development. Methodology: Project management methodology is selected as a tool. Project management is based on the application of a network planning technique (Critical Path Method), because of its suitability for representing the logical structure of environmental protection system. The survey was conducted in the area of the city of Kostolac. The examined area included mining and energy complexes in Kostolac, which incorporate three surface mines (Ćirikovac, Klenovik, and Drmno) and two thermal power stations (TE "Kostolac A" (100 MW) and TE "Kostolac B" (2 × 348.5 MW)). The PSR model (Pressures, State, Response) was used for the organization of the interactions within "society-environment" system as the basis for indicator selection. Results: Procedures to identify and determine the significance of the environmental aspects should be established by executive staff in mining and energy plants and complexes. Identification of environmental aspects is the first part of the planning system of environmental management and the activities related to them. The accomplishment of critical path activities represents the basis for improving the environmental protection system in mining and energy complexes. Discussion: Application of sustainable development principles depends on the country's energy potential and the application of the adopted environmental policy regarding mining and energy complexes. Strict enforcement of existing laws and regulations presents an opportunity to rectify many shortcomings while providing economic benefits, restoring the usable value of ravaged land, and preserving air and water quality.

Abstract. The term of radiation hazards is connected to the hazardous levels of ionizing radiation that could be harmful to the living tissue. Reflecting the contemporary lifestyle the World Health Organization (WHO), stated that as the use of ionizing radiation increases, so does the potential for health hazards if not properly used or contained. The increased rate of ionizing radiation can be attributed to the variety of anthropogenic activities, ranging from ore extraction, medical services, and energy production to military installations. On the other hand, radiation protection practices term indicates the measures directed to the protection of humans, in the first place, and other living organism from the harmful effects of exposure to ionizing radiation. In that sense, efficient and effective radiation protection from the perspective of society usually involves minimizing costs and capital commitment in any way. On the other hand, effective and efficient radiation protection management activities from the perspective of the army involve broader radiation protection measures during peacetime, emergencies and even wartime. The aim of this paper is to help the development of an integrative review for radiation protection, addressing the contemporary needs within the different but prominent stakeholders: civil and military structures. The paper offers an in-depth analysis of related core terms: radiation protection principles and modalities of protection. The applied methodology consists of comparative structure analysis and evaluation of available data. Obtained results are intended to be used in further implementation processes regarding the radiation protection practices both in civil and military structures.
