The city of Korça is situated in the South-East part of Albania. Korça’s climate is partly Mediterranean and Continental, characterized by cold winter and relatively hot summer. The average annual temperature is 10.6 oC, while the average rainfall is 720 mm. Heating of Korça is not an unknown issue, although it still remains unsolved despite many efforts in this sector. This paper shortly describes the building typology and their thermal characteristics in Korça. After defining the heating demand of the Korça city, where as input in the model are used demographic data, climate data, building typology and heating system. Energy scenarios for heating of the city rely on a
baseline scenario where wood is used as an energy source. Heat pump and natural gas energy scenario have been used for this comparative study. Energy and cost analysis for three scenarios are discussed in this paper.

The main features of the radiation environment in the surrounding environment are presented. Over the last 5 years no values other than the natural ones have been observed, with the lowest values in Veliko Tarnovo. The main characteristics of the radiation in operation in nuclear power plants and the major accidents resulting from the operation of the NPP in the development of humanity are shown. Radiation as a result of the uranium mining and uranium processing industry in Bulgaria is also under consideration. It also shows the actions of radiation as a result of other people’s activities.
