Determination of Natural Radionuclides for Water Resources on the West Bank of the Nile River, Assiut Governorate, Egypt

Abstract

Estimations of natural radioactivity levels were carried out for water (surface and groundwater) samples collected from the west bank of the Nile River in Assiut Governorate, Egypt. The activity concentrations in the water samples ranged from 19.20 ± 2.40 to 492.26 ± 71.52 mBq/L, from 15.58 ± 2.62 to 351.39 ± 66.13 mBq/L, and from 50.31 ± 5.58 to 2255.03 ± 249.42 mBq/L for 226Ra, 232Th, and 40K, respectively. In this work, the recorded activity concentrations have been organized statistically using a dendrogram cluster and a principal coordinate analysis. In view of the groupings of radionuclide activity, the average annual effective doses through ingestion for adults, children, and infants, despite the responsibility of each explicit radionuclide to the total dose, were assessed and debated. Children had the most important measurement calculations, making them the most regarded mass gathering. All estimations for each different water type, as well as for each individual population group, scored well under the recommended reference value of 0.1 mSv resulting from a one year’s intake of drinking water in accordance with the recommendations of the European Commission (EC) in 1998.

Radioactivity Measurements and Radiation Dose Assessments in Ground Water of Al-Baha Region, Saudi Arabia

“…The annual effective dose equivalents from the consumption of drinking water due to 226 Ra, 232 Th, and 40 K were estimated by UNSCEAR (2000) and El-Gamal et al (2019) as:…”

Evaluation of Radiological Health Risks in Popularly Consumed Brands of Sachet Water in Nigeria

“…Six age groups, that is, <1 y, 1-2 y, 2-7 y, 7-12 y, 12-17 y, and >17 y with their corresponding rates of water consumption 250, 300, 350, 400, 550, and 730 (L/y), respectively ( 15 , 34 , 35 ), were used for estimating the AED. In a similar manner, radiological risks/excess life-time carcinogenic risk (ELCR), that is, morbidity and mortality cancer risks were evaluated for radium isotopes ( 226 Ra and 228 Ra) using equation (3) ( 36 , 37 ).…”

Radon concentration and exhalation rate for granitic rocks, Central Eastern Desert, Egypt

“…Under standard conditions, it is gaseous and easily inhaled, therefore causing a health hazard. The exposure level to radon gas differs from place to place (El-Gamal et al 2019;ICRP 2014;Lecomte et al 2014;Salaheldin et al 2019Salaheldin et al , 2021Salaheldin et al , 2020aGünay et al 2019). It is a dangerous contaminant that affects indoor air quality worldwide.…”
