Radionuclide concentration in tea, cabbage, orange, kiwi and soil and lifetime cancer risk due to gamma radioactivity in Rize, Turkey

Abstract

Annual effective gamma doses were found to be higher than the world's average in soil samples. The excess lifetime cancer risks were only found higher than the world's average in soil samples.

Determination of radioactivity levels of soil samples and the excess of lifetime cancer risk in Rize province, Turkey

“…It is a product of fallout radioactivity. The 137 As shown in table 3, the radioactivity concentrations in soil samples were comparable to other studies in various regions (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(35)(36)(37)(38)(39)(40) . Karadeniz (8,12,17,19,25) .…”

“…Karadeniz (8,12,17,19,25) . Merdanoglu and Altınsoy et al, Orgun et al and Abbaspour et al determined a higher activity concentrations of 226 Ra and 232 Th compared to this study (13,20,35) . 40 K activity concentrations of Rize were also higher compared to studies conducted at other parts of Turkey (8,12,(14)(15)(16)(17)19,21,22) .…”

“…Measuring terrestrial gamma dose rates is also essential since gamma radiation provides information concerning excess lifetime cancer risks. Yet in Turkey, there are only a limited number of studies which evaluate soil radioactivity and terrestrial gamma dose rates (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) .…”

A preliminary study on 226Ra, 232Th, 40K and 137Cs activity concentrations in vegetables and fruits frequently consumed by inhabitants of Elazığ Region, Turkey

“…In addition, 137 Cs is the most important fission product released to the environment as a result of nuclear activities, because this radionuclide rapidly passes to foodstuffs and creates a dose effect [3]. The literature includes this type of studies [4–10]. The aim of this study is to determine the exposure dose of 226 Ra, 232 Th, 40 K and 137 Cs radionuclide concentrations in fruits and vegetables produced in the Elazığ Region of Turkey, which are frequently consumed by local residents.…”

Radionuclide concentration in cabbage samples due to gamma radiation in Samsun, Turkey

“…During the process of nuclear waste, the airbone particles may be intercepted by plants or return to help soil. Therefore, plants may get radioactivity nuclides by deposition of radioactive waste on the foodstuff directly and by absorption from the soil Measurement of the concentrations of radionuclides present in foodstuffs permits the determine of the dose caused by the intake of foodstuff [1]. Since gamma radiation provides information about excess lifetime cancer risk, determining gamma dose rate has also importance [2].…”
