Within the scope of this study,it is aimed to contribute to the efforts for forming a database including the natural radiation levels throughout the country and developing a foundation for radiation *** portion of the Euphrates valley within the provincial border of erzincan was chosen for the investigation and natural radiation levels were detected by analyzing the samples taken in terms of radioactivity,natural environment’s radiation *** the region of Karasu,29 different samples from the water and 17 from the soil were taken and their total alpha,beta activities were *** take samples from the water and then they were measured by low background counter(Berthold brand LB770 10-channel counter).Total alpha and beta analyses were made according to the standard *** values of alpha and beta concentrations of samples were measured as 0.0421 Bq/L and 1.806 Bq/L,*** the soil samples HPGe gamma spectrometer system was used and radioisotope activity concentrations were found within the intervals of 2.7-27.8 Bq/kg for 226Ra;3.2-39.4 Bq/kg for 232Th;98-714 Bq/kg for 40K;<0.4-57.8 Bq/kg for 137Cs,*** radioisotopes were detected in some of the samples taken from streaming beds joining river water.

This study deals with the climatic parameters and the climatic differences in Elazig and its close regions (cities of Malatya, Tunceli, Bing?l, erzincan). Data on mean monthly temperature, daily maximum-minimum temperature, rela-tive humidity, pressure, wind speed, rainfall, solar radiation and sunshine duration were analyzed and modeled for 10-year period, from 1994 to 2003. Malatya city was the hottest area whole period, while the erzincan city was the coldest area. Maximum temperatures were at highest values in Tunceli. Minimum temperatures reached the warmest values in the Malatya. erzincan city was the most humid area almost throughout the period while Malatya was the least humid area. Wind speed reached the highest values in the Elazig and the lowest values in the Tunceli. Pressure reached the highest values in the Malatya and the lowest values in the erzincan. Direct solar radiation reached the highest val-ues in the Tunceli and the lowest values in the erzincan. Sunshine duration reached the highest values in the Malatya and the lowest values in the erzincan. A regression analysis was carried out by using the linear regression technique to model the climatic parameters. The models developed can be used in any study related to climatic and its effect on the environment and energy. The models developed in this study can be used for future predictions of the climatic parame-ters and analysing the environmental and energy related issues in Elazig and its close regions (cities of Malatya, Tun-celi, Bing?l, erzincan).
