Effect of Zn Concentration On Structural and Optical Proprieties Of ZNO Thin Films Deposited By Spray Pyrolysis

ZnO thin film were deposited by spray pyrolysis on glass substrates, using zinc nitrate as precursor with different molar concentrations varying from 0.05M to 0.2 M. To study the structural proprieties of the film , the different technique was used as the X-ray diffraction, atomic force microscopy (AFM), Raman scattering , and FTIR . The optical properties were explored by transmission, reflectivity and Photoluminescence techniques. The ZnO thin films obtained in this paper are polycrystallines, the grain size increases when the molar concentration of Zn precursor was increasing. The films are transparent in visible region, this transmission values decreases when the molar concentration increase caused by the increasing of surface roughnes

Diurnal and seasonal influence on the indoor radon levels in dwellings of Sharjah Emirate as well its estimation of annual effective dose

Radon, a proven highly carcinogenic gas, has raised serious concerns, necessitating its measurement in residential areas. In the coastal city of Sharjah, United Arab Emirates (UAE), the first indoor radon concentration measurements were conducted. Following the Environmental Protection Agency (EPA) protocol, active radon detectors were employed in the living rooms of houses across the south-east region of the city. Measurements revealed that, the mean values during winter are of (39.6 ± 12.2) Bq/m3 (floor 1) and (35.7 ± 9.8) Bq/m3 (floor 2), while in summer, levels were slightly higher on floor 1 (55.8 ± 10.1) Bq/m3 compared to floor 2 (47.8 ± 12.6) Bq/m3. Ground floor analysis showed mean values of (57.0 ± 12) Bq/m3 in summer and (49.0 ± 16) Bq/m3 in winter. Higher summer levels were linked to climatic conditions and increased time spent indoors. The excess lifetime cancer risk for ground floor radon was estimated as 0.341% over 25 years. Annual dose equivalent was calculated using International Commission on Radiological Protection (ICRP) and United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) models. The calculated results were found to range from 1.7 to 3.0 millisieverts (mSv), which is within permissible limits
