“…In general, the average values of Ra eq for the studied cement samples were lower than the limit value of 370 Bq kg −1 recommended by Organization for Economic Cooperation and Development [32]. The terrestrial environmental radiation sources of indices dealing with the assessment of the excess gamma radiation arising from construction equipment such as outdoor and indoor hazard indices and gamma radiation indices has been investigated by several investigators [33][34][35][36][37][38][39]. For this study, the gamma index (I γ ) was computed using the relation recommended by the European Commission and used by [7,32]…”

This work deals with the measurement of the radioactivity concentrations from different cement samples collected from the South Gondar Zone, Ethiopia. The measurement of naturally occurring radioisotopes and radiation health impact indices caused by these nuclides in cement samples are indisputable in the dwellings. Specifically, the average concentrations for 226Ra, 232Th and 40K were estimated as 76.53, 81.67, and 407 Bq kg−1, respectively. It was seen that all the measured mean values were greater than the world’s limited levels. External and internal hazard indices are calculated as defined by the European Commission from the corresponding concentrations of 226Ra, 232Th and 40K nuclides. Moreover, the natural radionuclides have variety of concentrations which must be caused by the types of raw materials used in the industries for the production of cement.

“…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]. Whether they are created artificially or naturally, the various radioactive elements found in the environment are similar to other non-radioactive elements.…”

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.

“…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].…”

“…All ionizing sources produce an external radiation field, and all radioisotopes are hazardous if injected or ingested, So the workers in the nuclear medicine or radiation field in a hazard zone work and that affects the vital activities in the long term. Consequently, the hematopoietic system's sensitivity to the treatment, observing complete blood counts (CBC) has become monotonous for most worker while they carrying out their daily activities in radiation [9,10]. CBC monitoring is one of the standard examinations for examining the effect of radioactive doses.…”

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.
