Abstract
The aim of this study is to determine uranium (238U), potassium (40K) and thorium (232Th) in the radioactive elements by measuring the natural rocks in the vicinity of Antalya province by using High-purity Germanium (HPGe) Detector with gamma spectrometry 69. At the end of the measurements, total absorbed dose rates of the rock samples have been found to be within the normal range of values between 3.10 nGy/h and 117.35 nGy/h. While the minimum value of Raeq has been determined to be 6.36 Bq/kg at sample S8, the maximum value has been determined as 250.15 Bq/kg at sample S4. All of the values obtained at the end of the study have been determined to be lower than the maximum Raeq value (370 Bq/kg) and the limit values for industrial products which ranges between 370 – 740 Bq/kg. ARa, ATh and AK; 232Th, 40K and 226Ra of radionuclides are the activity concentrations in terms of Bq/kg. The hex value should be less than 1. The value is based on the upper limit of Raeq (370 Bq/kg). All of the results obtained are less than the limit value of 1.
Kurzfassung
Ziel dieser Studie ist die Bestimmung von Uran (238U), Kalium (40K) und Thorium (232Th) in den radioaktiven Elementen durch Messung der natürlichen Gesteine in der Nähe der Provinz Antalya mit Hilfe des hochreinen Germanium (HPGe) Detektors mit Gammaspektrometrie 69. Als Ergebnis der Messungen wurde festgestellt, dass die Gesamtenergiedosisleistungen der Gesteinsproben im normalen Wertebereich zwischen 3,10 nGy/h und 117,35 nGy/h liegen. Während der Minimalwert von Raeq bei der Probe S8 auf 6,36 Bq/kg bestimmt wurde, wurde der Maximalwert bei der Probe S4 auf 250,15 Bq/kg gemessen. Alle ermittelten Werte liegen unter dem maximalen Raeq-Wert (370 Bq/kg) und den Grenzwerten für Industrieprodukte, die zwischen 370 und 740 Bq/kg liegen. ARa, ATh und AK; 232Th, 40K und 226Ra von Radionukliden sind die Aktivitätskonzentrationen in Form von Bq/kg. Der Hex-Wert sollte kleiner als 1 sein. Der Wert basiert auf der Obergrenze von Raeq (370 Bq/kg). Alle erzielten Ergebnisse liegen unter dem Grenzwert von 1.
