A study of background radioactivity level for Tekirdag, Turkey

Area of Science:

• Environmental Science
• Radiation Physics
• Radiological Protection

Background:

• Assessing background radiation is crucial for public health and environmental safety.
• Tekirdag province, located in north-western Turkey, has not been extensively studied for its environmental radioactivity levels.

Purpose of the Study:

• To determine the background radiation levels in Tekirdag province, Turkey.
• To evaluate the potential health risks associated with natural and artificial radioactivity in the region.
• To establish a baseline for future radiological monitoring.

Main Methods:

• Indoor radon (222Rn) concentrations were measured using CR-39 nuclear track detectors.
• Gamma doses in air (indoor and outdoor) were measured using plastic scintillators.
• Radionuclide activity concentrations in soil and drinking water samples were analyzed using gamma-ray spectrometry and low-background counting techniques.

Main Results:

• Average indoor radon concentration was 86 Bq m(-3) (2.2 mSv/year).
• Average indoor and outdoor gamma dose rates were 5.7 and 5 µR/h (300 µSv/year), respectively.
• Soil samples showed average activities of 29 Bq kg(-1) for 238U, 39 Bq kg(-1) for 232Th, 580 Bq kg(-1) for 40K, and 5.2 Bq kg(-1) for 137Cs.
• Drinking water showed gross alpha and beta activities of 0.044 and 0.1 Bq l(-1) (9 µSv/year).

Conclusions:

• The overall background radioactivity level in Tekirdag is comparable to other regions in Turkey.
• The measured radiation levels pose no significant health risk to the population.
• The study provides valuable data for radiological health assessments in north-western Turkey.
