Measurement of radium-226 concentration and dose calculation of drinking water samples in Guilan province of Iran

Abstract

Background: 226 Ra) is a product of the 238 U radionuclide decay series that significantly incorporated into the human body through water intake. It can also poten#ally cause a series of health problems including cancers of the diges#ve system. Ra) is a product of the 238 U radionuclide decay series that significantly incorporated into the human body through water intake. It can also poten#ally cause a series of health problems including cancers of the diges#ve system. Materials and Methods: 226 Ra has been determined in drinking water samples collected from various loca#ons of Guilan province of Iran. The water samples are taken from public water and urban tap water sources. For evolu#on of gross a and b exposure precipita#on method and propor#onal scin#llator system was used. The radon emana#on method was used to measure the radium concentra#on in drinking water. Results: The measurements showed the gross α and β concentra#on ranges were between <38 mBql -1 to 92 mBql -1 and <41 mBql . According to UNSCEAR, the annual effec#ve dose value by inges#on is report to be 0.12 mSv y -1 .

Natural radiation of chemical fertilisers and radiological impact on agriculture soil

“…Natural radiation sources of terrestrial origin can be found in varying degrees in all media of the environment, including soil Ghods et al, n.d.), building materials(A. Abbasi, 2017;Akbar Abbasi, 2013;Abbasi and Hassanzadeh, 2017;Abbasi and Mirekhtiary, 2013), sediment (Abbasi, 2019;, water (Abbasi, 2018;Abbasi and Bashiry, 2016;, 2019, 2017, air (Lopes et al, 2018), and even the human body (UNSCEAR, 2000). One of the causes of radioactivity in soils other than those of natural origin is the widespread use of phosphate-rich fertilisers for agricultural reasons (Boukhenfouf and Boucenna, 2011).…”

222Rn,226Ra and 238U concentration in water samples for some marshes in Dhi-Qar governorate, Iraq

“…Geographic Information System (GIS) technology has been widely used in various fields, such as agriculture, business, geography, ecology, electricity and gas, emergency management and public safety, environmental management, forestry, health care, education, mining and geosciences, real estate, remote sensing, telecommunications, transportation as well as water distribution and resources (Abojassim & Rasheed 2019;Saleh et al 2019;Kiani et al 2021). The study of natural radioactivity (alpha emitters) was carried out by many investigators in different countries around Iraq and others throughout the world (Abbasi & Bashiry 2016;Abojassim & Mohammed 2017;Abojassim et al 2017aAbojassim et al , 2017bEl-Taher et al 2020). Many regions in the Dhi-Qar governorate have been bombarded In the recent wars that Iraq was exposed to in the previous period.…”

Assessment of Age-Dependent Effective Dose and Toxicity Risks of 226Ra and 228Ra In River Water Samples In Ondo State. Nigeria

“…It exists in four naturally occurring isotopes 223 Ra , 224 Ra, 226 Ra and 228 Ra. Many studies have been conducted on the occurrence and levels of 224 Ra, 226 Ra and 228 Ra in drinking water [3][4][5][6][7][8][9]. While radium-223 is a decay product of 235 U ( a rare uranium isotope), 224 Ra and 228 Ra originate from the decay of 232 Th.…”
