Accidental neutron exposure in a medical setting: a case study.

In May 2016, a new linear accelerator (Linac) was installed at a hospital oncology department. A team of individuals supervised the installation, including a Radiation Oncologist who acted as an independent observer to the installation, calibration, beam data collection and shielding measurements. In order to ensure the shielding was correct, a licensed representative of the Turkish Atomic Energy Authority carried out formal measurements of the gamma and neutron dose rates at a variety of locations in and around the Linac facility.

Heavy metal pollution in surface sediment and mussel samples in the Gulf of Gemlik.

Sediment quality data provide essential information for evaluating ambient environmental quality conditions. An evaluation is presented of heavy metal pollution, on the basis of statistical analysis of metal concentrations from the sediments of the Gulf of Gemlik, southeastern Marmara Sea, Turkey, which has been subject to high levels of pollution. The ranges for heavy metal concentrations (Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) at the <63 microm grain size were higher when compared with those obtained from >63 microm fractions.

Heavy metal levels in biota and sediments in the northern coast of the Marmara Sea.

Concentration of Cd, Co, Cr, Ni, Zn, Fe, Mn, Pb and Cu were determined in biota and sediment samples collected from the Marmara Sea in Turkey. The levels of Zn, Fe, Mn, Pb and Cu in the macroalgae are higher than previous studies in the Marmara Sea. Moreover, Cu and Zn concentrations at the present study are significantly high than Bosphorus and Black Sea algae.
