Eurasia Conference on Nuclear Science and Its Application, Presentations, Vol 1, (s. 387-389). 23-27 October 2000. İzmir, Turkey.http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/717I. Avrasya Nükleer Bilimler ve Uygulamaları Konferansı : 23-27 Ekim 2000. İzmir, Türkiye.The distribution of 226Ra in agricultural soils has been studied. Twenty four soil samples were collected to a depth of 20 cm from Aegean Region of Turkey. Activity concentrations of 226Ra in samples were determined by a radioanalytical method and measured by using an alpha scintillation detector. The radioanalytical method has been applied for the soil of 1 g to determine o f this radioisotope concentration. The both detection and chemical efficiencies were performed using standard radioactive solution of Ra-226. The recovery yield of radiochemically pure 226Ra was found to be 90%. The average concentration of 226Ra were 0.186 Bq/g and their distribution fitted a normal curve. The data obtained was evaluated to explain of 226Ra distribution in the agricultural area and compared with the other results in the literature.enginfo:eu-repo/semantics/openAccessAgricultural soilsTarımsal topraklarSoilToprakActivity concentrationAktivite konsantrasyonuRa-226conferenceObject387389
