“…Different studies in the same countries; Nigeria [ 30 , 31 ], Ghana [ 12 , 32 ] and Iraq [ 33–35 ] also had varying results. The result from the current study is higher than the results reported from Ghana (13:32), Nigeria [ 30 ], Egypt [ 36 ], Saudi Arabia [ 37 ], Malaysia [ 38 ] and Iraq [ 35 ] but lower than the results from Brazil [ 39 ], Nigeria [ 31 ] and Iraq [ 33 , 34 ]. Although the AED from the ingestion of water (AED w ) from this study is above the guidance level of WHO, it is within the range of values reported in literature.…”

This study assessed the potential radiological risks associated with the activities on Olusosun dump site on workers and dwellers of Olusosun community. The activity concentrations of 238U, 232Th and 40K from of soil and water samples were determined using High-Purity Germanium (HPGe) detector. The background radiation level of Olusosun dump site was measured using a portable Geiger-Müller counter-Radeye B20 survey meter. The mean value of background radiation was 1.46 mSv/yr. This value is about 46% higher than the recommended reference level of 1.0 mSv/yr for the public. The mean activity concentrations of 238U, 232Th and 40K in the soil samples were 19.1 ± 3.2, 29.1 ± 4.4 and 171.5 ± 6.1 Bq/kg respectively which are about 45.4%, 35.3% and 59.2% lower than the world’s average levels. For the water samples, the mean activity concentrations obtained for 238U, 232Th and 40K are 0.4 ± 0.4, 0.8 ± 0.2 and 0.8 ± 0.3 Bq/l respectively. These are about 99.9% and 20% lower than WHO reference levels for 238U and 232Th. The mean absorbed dose rate in air (D), Annual effective dose (AED) outdoor, Radium Equivalent (Req), External hazard index (Hex) internal hazard index (Hin) and Excess lifetime cancer risk (ELCR) from soil samples were 33.6 nGy/h, 41.0 μSv/yr, 73.1 Bq/kg and 0.2, 0.3 and $1.4\times{10}^{-4}$, respectively. Absorbed dose in air D, AED outdoor, Req, Hex, Hin and ELCR are 41.1%, 41.4%, 80.3%, 80%, 75% and 50% lower than their corresponding world’s average and references. The estimated AEDw from ingestion of water is 148.9 ± 50.4 μSv/yr, this is about 49% higher than the WHO reference level of 100.0 μSv/y from ingestion of water. The radiological hazard indices estimated from soil samples do not indicate any potential risks to the users. The elevated background radiation level of the dump site, and AEDw from ingestion of water, however, suggest that the activities on Olusosun dump site pose potential radiological risks on workers on the site and the public from consumption of water from Olusosun community.

“…Table (5) summarized the values of 226 Ra, 232 Th and 40 K activity concentrations in other countries and those from the present study. As can be seen from table (4) and figure (6): 226 Ra activity concentrations were found in values higher than that reported by Alfatih et al, 2008 in Sudan [25], Violeta et al, 2020, in Romania [16], Nuraddeen, 2016 in Malaysia [29] and lower than that reported by Ajayi, 2012 in Nigeria [26], Eric, 2014 in Ghana [28], Alaboodi et.al., 2020 in Iraq [1], and by Khoirul et al, 2020 in Malaysia [19]. 232 Th activity concentrations were found in values higher than that reported by Alfatih et al, 2008 in Sudan [25], Violeta et al, 2020, in Romania [16], Nuraddeen, 2016 in Malaysia [28] and H Saad and N Aref 2021 in Iraq [10] and lower than that reported by Ajayi, (2012) in Nigeria [25], Eric, 2014 in Ghana [26], Alaboodi et.al., 2020 in Iraq [1] and Wiseman, 2015, in Ghana [27].…”

In the present work, we have measured specific activity concentrations of in eleven tap water samples for selected regions in Aden governorate by using high purity germanium detector (HPGe). The (HPGe) detector (CANBERA-model 7229N, USA) with an efficiency of 35% and energy resolution (2.6keV) at energy (1332.6keV) for 60Co, the high purity N-type semiconductor detector with physical characteristics of (geometry closed-end coaxial, (3×3 inch). The results have shown that, The highest value of specific activity concentration of 226Ra was found in in T7 Daar-Saad region which was equal to (0.525±0.29)Bq/L, while the lowest value of specific activity concentration of 226Ra was found in T11 Aden Assughra region which was equal to (0.017±0.006)Bq/L with an average value of (0.228±0.13)Bq/L. The highest value of specific activity concentration of 232Th was found in in T5 Khor-makser region which was equal to (0.319±0.18)Bq/L, while the lowest value of specific activity concentration of 232Th was found in T11 Aden Assughra region which was equal to (0.009±0.001)Bq/L with an average values of (0.129±0.089)Bq/L. The highest value of specific activity concentration of (40K) was found in in T2 (Al-Ma,allah) region which was equal to (0.4±0.26)Bq/L, while the lowest value of specific activity concentration of (40K) was found in T11 Aden Assughra region which was equal to (0.027±0.004)Bq/L with an average values of (0.141±0.021)Bq/L respectively. The annual ingestion effective dose (AED) ranged from (3.05 to 98.77μSv/y), (5.67 to 178.16μSv/y), and (3.41 to 119.08μSv/y), with average values of 42.65μSv/y, 78.62μSv/y and 48.62μSv/y, for infants, children and adults respectively. The excess lifetime cancer risk (ELCR) have been calculated, its values were lower than the world’s average value of (0.29×10−3) as reported by EPA. The overall annual effective dose and cancer risks corresponding to radionuclide intake in tap water were below the recommended maximum values. It was inferred from the findings of this study that the water used as the sample does not have any significant radiological impacts to human body and is safe to be used as drinking water.

“…Because of the relationship between factors such as pregnancy, duration of radiation exposure, and degree of radiation damage, a physician's lack of awareness of radiation protection can have a significant impact on a patient's health. According to studies, physicians and medical students have a poor understanding of the harmful consequences of radiation applied in clinical trials (15). In a recent study, a lot of medical students may face a variety of emotional and academic obstacles during clinical trials, but little is known about their experiences (16).…”

An effective radiation protection program requires an effective oversight and feedback mechanism to management. A main objective of the radiation protection program is to decrease radiation doses wherever and whenever reasonably possible, hence lowering the health risk that is thought to be proportionate to the radiation dosage. Justification of operations requiring radiation exposure, as well as the use of minimal radiation exposure simply adequate for diagnostic and interventional procedures, should all be part of a radiation protection policy. National authorities must support the development and implementation of radiological safety and security in organisations that employ radiation sources. Maintaining a high level of competence is critical for the development of future safe ionizing radiation applications. Patients, physicians, and employees across many departments, including radiology, interventional cardiology, and surgery, are concerned about radiation safety. Radiation released during fluoroscopic operations is the source of the highest radiation dosage for healthcare workers. Radiation from diagnostic imaging modalities such as computed tomography, mammography, and nuclear imaging are minimal factors to healthcare personnel's cumulative dose exposures. Radiation exposure, on the other hand, poses a risk to both patients and healthcare professionals. The medical use of ionizing radiation is a huge and growing global activity. While the use of ionizing radiation in medicine provides enormous advantages to the worldwide population, the inherent hazards owing to stochastic and deterministic effects necessitate the need to safeguard patients from potential injury. Current issues in radiation protection of patients include not only the rapidly increasing collective dose to the global population from medical exposure, but also the fact that a significant percentage of diagnostic imaging examinations are unnecessary, and the cumulative dose to individuals from medical exposure is increasing.
