PERFORMANCE TESTS OF ACTIVE PERSONAL DOSEMETER DEVELOPED BY ÇNRTC/NEL.

The Active personal dosemeter (APD) developed by Çekmece Nuclear Research and Training Center/Nuclear Electronic Laboratory (ÇNRTC/NEL) was calibrated at the reference radiation quality (137Cs). The performance tests were carried out with 137Cs, 60Co and X-ray beam qualities in compliance with the standards of International Organization for Standardization ISO4037-1,3 and The International Electrotechnical Commission, IEC61526:2010. Response of the personal dose equivalent was observed to be within the range from -7.

A study of environmental radioactivity measurements for Cankiri, Turkey.

This study is the first to assess the level of background radiation for the Cankiri province of Turkey. Indoor air radon concentrations were determined using Columbia Resin-39 nuclear track detectors and the average (222)Rn activity was found to be 44 Bq m(-3) (equivalent to an annual effective dose of 1.1 mSv).

Determination of the health hazards due to background radiation sources in the city of Adapazari, Northwestern Turkey.

Human body is exposed to ionising radiations both internally and externally by mainly high-energy cosmic ray particles incident on the earth's atmosphere and radioactive nuclides that originated in the earth's crust. The main objective of this study is to assess the health hazards due to environmental radiation sources in the city of Adapazari, one of the most important industrial cities of the country, Northwestern Turkey. For this purpose, natural radiation sources, external terrestrial radiations, cosmic radiations, and inhalation exposures have been investigated.
