“…Figure1 shows the effects of radiation exposure on Red Blood Cell RBC count before and after radiation exposure. As well as, table (2) shows these results for eight cases working on these devices. By comparing the results for each case, it shows that the count of the RBC slightly decrease after exposure, It has been observed that there is continuously a minor reduction in the entire number of red blood cells after exposure to ionizing radiation; Thus, the RBC.…”

“…The radiant energy amount is placed per substance unit mass, identified as the absorbed dose. When living tissues absorb the radiation, both of the radiation's type and the absorbed dose are significant in defining the damage degree that might happen [1][2][3]. External exposure of radiation is occurring when the body is exposed to penetrating radiation from an external source while the internal one involves contamination with radioactive material [4].…”

In this study, eight cases of workers in gamma camera scans and Positron Emission Tomography (PET/CT scan) fields (employed for various medical diagnoses) had their complete blood counts (CBCs) assessed. From the first hour of work until the last, the investigation of radiation’s impact on hematology was ongoing. By using a personal dose meter (Geiger Badge), the radiation exposure reading for a whole workday is directly recorded in (μSv). The study concluded that while the number of WBC count increased for all workers after radiation exposure, the number of RBC count decreased after exposure, suggesting that RBC amount may be a reliable indicator of exposure degree.

Chaotic systems have become widely adopted as an effective way for secure data communications, because of its simple mathematical complexity and good security. The relationship between encryption algorithms and chaos systems has gained a lot of attention in the past few years, since it avoids the data spreading as well as lower the transmission delay and costs. In this paper a novel 3D discrete chaotic map is proposed for data encryption and secure communication and named as WAM. For secure communication, the Pecora and Carroll (P-C) method was utilized to achieve synchronization between the master system and the slave system. The simulation results of WAM 3D discrete chaotic map showed that the system has a chaotic behavior and a characteristic randomness and can pass 0-1, Lyapunov exponent (LE) and NIST tests which are usually used to check chaotic behavior. The statistical outcomes of the LE test were 0.0193, the frequency test (FT) was 0.4237, and the run test (RT) yielded a value of 0.0607. As a result, it enrich the theoretical basis of the equations and implementation of chaos, and it is superior for encryption algorithms and communication security applications.

“…Radiation can also be created artificially, like in X-rays, by atomic power plants, or it can occur naturally, like in the water we drink or in the soil. In addition to cosmic radiation, the radioactive elements are produced by the decay of the uranium chains U-235, U-238, and thorium Th -232, as well as potassium 40-K [1,2]. Building materials, water, air, soil, rocks, petroleum, chemical, metallurgical, cement, and fertilizer products all contain radioactive elements [3][4][5].…”

Natural radioactive materials known by the term (NORM) are among the most important sources of radiation that can be transmitted to humans through eating foodstuffs. Therefore, researchers took care to study the levels of this type of radiation. In the current study, the levels of radioactivity were determined for the three most important natural radioactive elements, uranium (U-238), thorium (Th-232), and potassium (K-40) in (29) of the most consumed food samples collected from Wasit Governorate Markets. A gamma-ray spectroscopy system consisting of a sodium iodide activated thallium detector (NaI)Tl with dimensions of “3×3” and electronic units attached to it was used in this study. The results obtained from the studied samples showed the concentrations of (U-238, Th-232, and K-40), the value of the annual effective dose, the equivalent concentration of radium Raeq-226, and external and internal risk factors indicated that all concentrations of the radioactive elements targeted in the study were within the permissible limits despite the discrepancy in the values of the concentrations of these elements according to the samples.
