Abstract In this paper, the results of ambient dose equivalent rate measurements at different locations are presented. At every location measurements were performed twice a day, in the morning and afternoon. One of the aim of this study was to determine the impact of weather conditions on the ambient dose equivalent rate. Correlation between ambient dose equivalent rate values and the meteorological parameters such as temperature, pressure and relative humidity are analyzed. A moderate positive correlation was found between the ambient dose rate and pressure in the morning measurements. The average annual effective dose is calculated to be 0.105 mSv. Keywords Ambient dose equivalent rate · Meteorological parameters · Correlation · Annual effective dose · Outdoor
Introduction The natural and artificial radionuclides contribute to the exposure of ionizing radiation. Exposure to natural sources of radiation is inevitable. Natural radiation has origin everywhere in the environment, in space, earth, air, water, food, etc. [1]. The sources of natural radiation are the primordial radioactive elements and their radioactive decay products as well as the radionuclides produced by cosmic-radiation interactions [2]. The natural radionuclides which contribute to the environmental background radiation are the terrestrial radionuclides, 40K, 226Ra and 232Th. These radionuclides are not uniformly spread in soils, as such they vary according to geology and geography of different environment [3, 4]. Gamma radiation emitted from terrestrial radionuclides is the main source of irradiation of the human body. The geological and geographical conditions affect the natural environmental radioactivity and the associated external exposure due to gamma radiation [5, 6].

reported this influence at different levels in the soils of different regions around the world [5, 7]. Environmental monitoring is essential for assessment of radiation effects on humans and environment [8]. Enhanced levels of radioactivity in some area can be found by measuring the ambient dose equivalent rate [9]. Many studies have been performed in order to determine the ambient dose equivalent rate in different environments and correlate those values with other parameters of interest [10–15]. Ionising and cosmic radiation have affect on the ambient dose equivalent rate level in the environment [15]. The ambient dose equivalent rate mainly depends of the meteorological parameters such as the t
