In this paper, the nano Silver dioxides films have been deposited using the reactive pulsed laser deposition method (RPLD) using the tattoo removal Q-swithing Nd-Yag laser, at the value of the wavelength of 1064nm, pulseduration of 6 sec, and 800 mJ energy of laser have been applied for ablated an extra purity of the Silver target then deposited the nano siver oxide particles on the silicon substrates, synthesize and studying of the rapid thermal annealing (RTA) effects on the structural properties, the morphological properties, the Optical properties, the electrical properties and finally the solar cell properties for the prepared samples. Both X-ray diffraction and electron microscopy studies show that the structure of the film depends on the annealing teamperatures effects of the deposited film. The nano silver oxide is present in different crystalline stages, where the particle sizes have been increases with increasing heat treatment from 45nm to 75 nm. The analized Results of the optical aprove the improvements of the absorption lead to decreasing the reflection values compared with the surface of the silicon (crystalline Si), where the transparency for the range of larger than 300 nm and the values of the optical band gap of 2.12 eV. The synthesized results for the solar cell fabrications present a clear improvement in the solar cell quantum efficiency values in the case of silver nano oxide deposition and annealed with the high degree, where the value of the efficiency about of 4.22.

This research presents a statistical study of radiation generated from communication towers in the Nineveh Plain region Baghdeda. The intensity of radiation energy was measured at 10 meters away from the communication tower in different locations, using a (1PC XH-901 Dosimeter/ Personal Dose Alarm / Radiation Detector, dosage rate: 0.01 μSv/h to 150μSv/h) to measure the amount of radiation at various times. Energy densities were measured and compared with standard limits provided by other authorities, such as the International Committee for Radiation Protection. Results were analyzed using SPSS version 26 to implement the data. The results show that the means of the radiation levels measured at all the zones do not statistically differ from the highest values determined globally 0.50-1.70 μSv/y; they lie within the radiation-free zones. Civilians may not always have a choice where the mobile tower will place. As a result, it may rely on some quick fixes, such as certified radiation protection items that offer all-around protection from mobile tower irradiance. The radiation shielding technology used in these goods alters the nature of irradiation from a constant to a variable waveform, rendering it useless.

Model was used to estimatenet Net Radiation falling on horizontal surface in Mosul, Baghdad and Nasiriyah stations for the time series . Results showed that there is a sort of relatedness between estimated and measured incoming short wave radiation(Rs) in the three stations, where the values of mean absolute error (M.A.E.) is not exceed (11,14,24)% in Baghdad, Nasiriyah and Mosul respectively. Rn estimated by the Model appear that Mosul station gives the lowest values of Rn in comparison with Baghdad and Nasiriyah stations, this is due to the amount of incoming solar radiation reached the earth surface. Summer months in Nasiryiah gave also values of Rn lower than that in Baghdad because of the sand storm which domain during the summer months in Nasiriyah. Two linear Regression Equations were found, the first between net radiation and net incoming short wave radiation (Rn & Rns ) and the second between net radiation and net long wave radiation (Rn & Rnl ) in each of the three stations. The correlation coefficient (R) found in the first relation is very high and ranged between (0.98 -0.99 ), while the values of ( R ) in the second relation ranged between ( 0.67 -0.87 ). Liner Regression Equations were also found between Rn and meteorological elements (Temperature, Relative Humidity, wind Speed and Sun Shine Ratio ) in each of the three stations.
