Abstract

Summary

Environmental radioactivity level of the former Trabzon municipal solid waste dumpsite were investigated by in-situ gamma-ray spectrometric method. The natural radioelement concentrations on the surface of dumpsite were measured using a portable gamma-ray spectrometer. Spectrometry data were collected on the ground surface at 231 points along 21 profiles, parallel to each other, where the interval for both measurement points and each profile are 10 m. The measuring time was set to be 300 s at each point. The average activity concentrations of 238U, 232Th, 40K and dose rate in the dumpsite are 42.68 Bq/kg, 49.88 Bq/kg, 417 Bq/kg, and 67.91 nGy/h respectively. In addition, radiation hazard parameters were calculated and compared with the international standard values. Consequently, it was found that there is no significant radiologic hazard and risk for humans and the environment in studied area.
