“…Several foreign institutions are currently involved in salvage archaeology in the region under the umbrella of Merowe Dam Archaeological Salvage Project (MDASP). Resettlement and compensation were mainly offered to Manasir, Hamadab and Amri tribes [5]. Merowe dam constrained again several local settlements to be displaced in desert regions and famous archaeological sites like Napata besides the Merowe dam [6].…”

This study investigates the existence of high levels of radiation and heavy metallic materials in the area around Merowe Dam, using different physical techniques. Two radiation survey-meters were used in order to compare results, which were Raddose and Idintifineder and several analytical devices. The survey-meter measurements were 0.1 µSv/h over the chemical waste and 0.05 µSv/h in different areas positions. The background level of radiation was determined at different positions, and the average of the measurements was 0.09 µSv/h, which was within the normal ranges. The existence of natural occurring radioactive material falls within the global wide range as well. Furthermore, the presence of the chemical materials containing heavy metals was detected by using Inductively Coupled Plasma Emission spectrophotometer (ICPE-9000), Energy Dispersive X-ray Fluorescence (EDX-8000) devices and Gas chromatograph GC-2010 plus. The analysis showed there were lots of heavy metals that they were believed to be a revert from the dam construction material, such as paint and epoxy.

In this study, the natural radioactivity level and its effects on the environment of Lake Van, which is the largest lake in Turkey, were investigated extensively. Initially, 254 soil samples have been collected from the districts (Tusba, Edremit, Gevas, Tatvan, Ahlat, Adilcevaz, Ercis) located around the coastline of Lake Van in eastern Turkey. A Na(TI) detector was used to detect activity concentrations of radium (226Ra), thorium (232Th) and potassium (40K) in each collected soil sample. The obtained average results were compared with available data from Turkey and international data base. The average activity in soil samples was measured as 28.0 ± 3.7–43.6 ± 2.2 Bq/kg for 226Ra, 27.3 ± 4.1–55.4 ± 4.8 Bq/kg for 232Th and 377 ± 42– 706 ± 40 Bq/kg for 40K. It was observed that the average concentrations of 226Ra, 232Th, 40K (43.6 ± 2.2, 55.4 ± 4.8, 706 ± 40 Bq/kg, respectively) for Tatvan district and (37.0 ± 3.5, 51.4 ± 4.2, 479 ± 41 Bq/kg, respectively) for Ahlat district were higher than both national and international average value. In addition, radiological effect parameters originating from terrestrial natural radionuclides for the study area; gamma dose rate (Dout), annual effective dose equivalent (AEDE), and lifetime cancer development probability (LCR) were calculated. The Dout, AEDE, LCR (83.0 ± 3.9 nGy/h, 0.102 ± 0.005 mSv/y, 0.36 ± 0.02 x 10–3, respectively) parameters in Tatvan district were found to be above the international allowable value.
