Human life depends on water and soil where our food mostly needs to be grown. Let us not forget the nature and rocks that we are surrounded in terms of structural base. For that reason, it’s crucial to determine their radioactivity level not just to help mapping the country’s radiation background measurements, but to assess people’s safety and protection. Especially, the International Atomic Energy Agency (IAEA), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), World Health Organization (WHO), or the International Commission on Radiological Protection (ICRP) develop safety standards to protect the health and to minimize the danger for people’s life before anything happens. In this specific study, the most densely populated county, called Siverek, in the region of Sanliurfa municipality was selected. For the analysis of soil and rock, respectively 11 and 7 distinctive locations were considered to determine the activity levels in Harran University laboratory. As to water samples, only two samples were proceeded to detect total alpha and beta activities by Cekmece Nuclear Research and Education Centre (CNAEM) by Turkish Atomic Energy Agency (TAEK). With regard to analysis tools, Ortec brand NaI(Tl) scintillation detector was used to detect any activity based on naturally occurring radioactive materials (NORM), such as 238U, 232Th, and 40K elements in soil and stone samples with the help of digibase MCA system. For water activity level investigation, low-level activity measurement system of LB770-PC with 10 channels, were used. As a result, it’s expected to find the levels of the most encountered activity units; such as Radium equivalent dose, indoor and outdoor external absorbed doses, internal and external hazard indices, indoor and outdoor annual effective doses, indoor and outdoor excess life-time cancer risks lower than the values that some organizations stated in their literature.

The excitation function of Mg28 above the α-decay threshold has been measured for the first time using the resonant scattering of α particles with the technique of a thick target in inverse kinematics. Thirteen new states are reported between Ex=15.5 and Ex=20.5 MeV, and suggestions for spin-parity assignments are given for two of these. Calculations of the branching ratio to α decay for these states as well as comparison of the measured cross sections to calculations suggest that α+Neg.s.24 clustering is not dominant in this energy regime.

International audience; The changing of the nuclear shells for light, neutron-rich nuclei, and the single-particle nature of 26Na, has been explored by studying 25Na(d, p)26Na in inverse kinematics, using a beam of 25Na ions at 5 MeV per nucleon, provided by the ISAC-II facility at TRIUMF, Vancouver. Charged particles were detected with a highly-segmented silicon array that surrounded the 0.5 mg/cm2 (CD2)n target. Gamma rays from the recoiling 26Na nucleus were detected using eight Compton-suppressed HPGe clover detectors. Recoil tagging was provided by an in-beam scintillation foil, downstream of the germanium array. A novel technique of utilising pγ- and pγγ-gating to extract proton angular distributions from states populated close in energy was employed with success. New states in 26Na that are populated directly have been identified, using γ-decay patterns. Shell model calculations for comparison to experimental results are ongoing, using different model bases.

International audience; An experimental technique for studying elastic scattering using a thick gas target is described, with a measurement of the α((24)Ne,α) reaction used as an example. Advantages such as ease, detector efficiency, and the possibility of measuring the cross section at 180° in the centre-of-mass are discussed. It is shown that a resolution of tens of keV is practical at zero degrees, and that the dominant contribution to the resolution for large angles is angular straggling of the beam in the entrance window. The use of helium gas as the target allows direct measurement of a-cluster states.

International audience; States in 26Na were populated in the (d, pγ) reaction, induced by bombarding deuterium target nuclei with an intense reaccelerated beam of 25Na ions from the ISAC2 accelerator at TRIUMF. Gamma-rays were recorded in coincidence with protons and used to extract differential cross sections for 21 states up to the neutron decay threshold of 5 MeV. Results for levels below 3 MeV are discussed in detail and compared with shell model calculations and with previous work. The angular distributions of decay gamma-rays were measured for individual states and are compared to theoretically calculated distributions, highlighting some issues for future work.
