Determination of natural radioactivity levels of some concretes and mineral admixtures in Turkey
Baltaş, Hasan; Kiriş, Erkan; Ustabaş, İlker; Yılmaz, Esra; Şirin, Murat; Kuloğlu, Emrah; Güneş, Banu Erdoğan (Asian Journal of Chemistry, 2014)Nine concrete samples with or without mineral admixtures have been analyzed for their naturally occurring radionuclide of Ra-226, Th-232 and K-40 using HPGe gamma spectrometry. Also, concrete raw materials such as aggregate, ... -
Effect of annealing temperature on K-shell X-ray fluorescence parameters of zinc oxide thin films prepared by the sol-gel method
Şirin, Murat; Baltaş, Hasan; Kiriş, Erkan; Keskenler, Eyüp Fahri (Taylor & Francis Inc, 2019)Zinc oxide thin films were grown on a glass substrate by a sol-gel process using a spin-coating technique. the obtained thin films were annealed between 350 degrees C and 550 degrees C in 50 degrees C steps and were then ... -
Effects of ultraviolet light on B-doped CdS thin films prepared by spray pyrolysis method using perfume atomizer
Novruzov, V. D.; Keskenler, Eyüp Fahri; Tomakin, Murat; Kahraman, Süleyman; Görür, Osman (Elsevier Science Bv, 2013)Boron doped CdS thin films were deposited by spray pyrolysis method using perfume atomizer. the effects of ultraviolet light on the structural, optical and electrical properties of B-doped CdS thin films were investigated ... -
Enhancing magnetic levitation and guidance force and weight efficiency of high-temperature superconducting maglev systems by using sliced bulk YBCO
Abdioğlu, Murat; Öztürk, U. Kemal; Güner, Sait Barış; Öztürk, Mehmet; Mollahasanoğlu, Hakkı; Yanmaz, Ekrem (Wiley, 2023)We aimed to enhance the magnetic force efficiency of Maglev systems without increasing total weight. For this aim, we divided YBCO bulks into three slices horizontally to utilize the YBCO-permanent magnetic guideway (PMG) ... -
Investigation and mapping of natural and artificial radioactivity in sediment samples from Borcka Black Lake, Artvin-Turkey
Dizman, Serdar; Akdemir, Tolga; Yeşilkanat, Cafer Mert; Nevruzoğlu, Vagif; Bal, Esra; Keser, Recep (Taylor & Francis Ltd., 2022)All living creatures in nature are constantly exposed to ionising radiation, which is emitted from natural and artificial radiation sources. For this reason, it is important to monitor the levels of radioactivity in living ... -
