“…The average activity concentrations of 137 Cs were found to be 12.07 ± 0.03 Bqkg -1 , 7.55 ± 1.68 Bqkg -1 and 1.33 ± 0.6 Bqkg -1 respectively. These differences in the average activity concentration of the 137 Cs radionuclide in the soil samples in the current study confirm that the low content of clay and high content of organic matter in the soil of mountain area can be considered lead to a higher radiocaesium contamination level than at the other two locations, in addition to the transport of radiocaesium due to high amounts of rainfall in the latter two locations (Kiss et al, 1988).…”

“…The graded liner comprises a 1 mm thick tin layer and a 1.5 mm thick copper layers to prevent interference by lead X-rays. To minimise scattered radiation from the shield, the detector was centred within it (Karataşlı et al, 2016). Gamma spectroscopy analysis was performed with the Genie-2000 software system interfaced with a multichannel analyser model DSA-1000, which is a full-featured 16K channel multichannel analyser with advanced digital signal processing techniques.…”

Gamma ray spectroscopy analyses have been carried out on 32 soil samples from the Marapasta area for activity concentration comparisons and hazard effects due to the 137 Cs radionuclide for the first time in this region. The average activity concentration of the 137 Cs in the soil samples was measured using HPGe detector systems. The anthropogenic radioactivity levels of 137 Cs in the samples collected from the bottom-of-hole soil at Marapasta, in the undisturbed areas near the bottom of the mountain chain and for the cultivated agricultural areas were found to be of an average value of 12.07 ± 0.03 Bqkg-1 , 7.55 ± 1.68 Bqkg-1 and 1.33 ± 0.6 Bqkg-1 respectively. In order to evaluate the radiological hazards effects due to 137 Cs in the samples, the absorbed dose rate (D), the annual effective dose rate (AEDR), the excess lifetime cancer risk for outdoor and total exposures (ELCR) in the soil samples were also determined. The results have been compared with the worldwide average range of radioactivity measurements. The three different ranges obtained in this survey indicate that there are different levels of radioactive hazard related to man-made radionuclides in the area and could serve as a first baseline for 137 Cs.

“…After getting the average of three different measurements, results were recorded in µR h -1 and then the conversion factor of 8.7 nGy µR -1 was used to change the unit of µR h -1 to the nGy h -1 . To obtain the annual effective dose equivalent (AEDE), the following equation was used [11,12].…”

Outdoor absorbed gamma dose rates were measured in 118 different regions at a height of 1 m above the ground in the gonad (genitals) level in humans in Kahramanmaraş province and its vicinity using Eberline portable detector. Outdoor gamma dose rates varied from 32.7 nGy/h and 96.4 nGy/h with an arithmetic average of 64.8 nGy/h. The average value of the corresponding annual effective dose rate was estimated as 79.5 µSv/y. Lifetime cancer risk values estimated according to ICRP 103, BEIR VII and ICRP 60 were found to be 0.032, 0.036 and 0.040 respectively.

Anahtar KelimelerYer fıstığı, Radyoaktivite, Gama spektrometresi, HPGe, Yıllık etkin doz Özet: Son zamanlarda birçok ülkede çevresel örneklerdeki (toprak, su, gıda vs.) radyonüklit miktarı hakkında araştırmalar yapılmıştır. Bu çalışmanın amacı, HPGe detektörlü yüksek çözünürlüklü gama spektrometresi kullanılarak Osmaniye ili ve çevresindeki farklı yerlerden toplanan yer fıstığı örneklerinde Karasal;(Ra-226, Th-232 ve K-40) ve antropojenik (Cs-137) radyonüklitlerin aktivite konsantrasyonu ölçmektir. Fıstık örneklerindeki Ra-226, Th-232 ve K-40 aktivite konsantrasyonları(Bq/Kg) sırasıyla, 3.1±1.0'den, 7.6±1.0'e, 3.2±1.0'den 6.6±1.8'e, 256±2.9'den 304.5±7.2'ye arasında değişmektedir. Cs-137 aktivite konsantrasyonu MDA değerinin altında kalmıştır. Investigation of Radiation Activity Growing Peanuts in Osmaniye KeywordsPeanut, Radioactivity, Gama spectrometry, HPGe, Annual effective dose Abstract: In recent years a lot of reviews on radionuclide that environmental samples contained soil, water, nourishment and et al were done in many countries. Aim of this study is to determine the specific activities of important natural and artificial radionuclides such as Ra-226, Th-232, K-40, and Cs-137 peanut that gathered from Osmaniye and various locations around. The specific activities of Ra-226, Th-232, and K-40 ranged from 3.1±1.0 to, 7.6±1.0 Bq/Kg, from 3.2±1.0 to 6.6±1.8 Bq/Kg, from 256±2.9 to 304.5±7.2 Bq/Kg, respectively. The specific activities of Cs-137 were generally remained below detection limits (MDA).
