determining the fraction of bioethanol-gasoline blending. The basic principle
of the technique is to measure the radioactivity level of <sup>14 </sup>C
isotope with the half-life of 5730 years, which is formed naturally and reaches
to equilibrium in the bodies of all the living organisms. Gasoline is produced
from petroleum, which is formed by the organisms that had died millions years
ago and exposed to pressure and heat under the ground. In addition, bioethanol
is a type of biofuel, obtained from fermentation of such crops like sugar beet,
sugar cane, corn and sweet sorghum. Owing to the fact that the <sup>14 </sup>C radioactivity
level in gasoline becomes to the unmeasurable levels within millions years and
the bioethanol has <sup>14 </sup>C level in equilibrium with the atmosphere, it
is possible to determine the blending ratios of gasoline and bioethanol. </span> </p> <p> </p> <p style="text-align:justify;text-indent:36pt;margin-bottom:9.6px;"> <span lang="en-us" style="font-family:’Times New Roman’, serif;font-size:12pt;" xml:lang="en-us">In this study, the applicability of the determination
of the ratio of biological additives in gasoline by the liquid scintillation
counting technique was investigated. Gasoline-bioethanol mixture ratios were
determined successfully in the commercially available gasoline and bioethanol
mixtures. </span> </p> <p> </p>}, number={1}, publisher={T.C. Türkiye Enerji, Nükleer ve Maden Araştırma Kurumu}
