Determination of Radon gas in bottled and sachet water in Ile-Ife, Nigeria

Abstract

The environmental monitoring of radon contents in some bottled and sachet water were carried out, with the aid of an active radon device (RAD7) made by Durridge, USA. This study is aimed to determine the level of radon in selected bottled and sachets water in major market in Ile-Ife, with a view to establishing the health risks that could arise in consumption of the water. The results obtained in this study show that all the water samples were safe for consumption without any health implication from radiological point of view.

Age-dependent Radiological Risk Assessment of Radon (222Rn) in Samples of Commercial Bottled Water from Benin City, Nigeria

“…The radon activity concentrations, as presented in Table The mean radon concentrations obtained in this study are slightly higher than those obtained by [6] in China, [26] in Turkey, [8] in Iraq and [9] in Katsina, Nigeria, as shown in Table 2. [12,7,2] reported radon mean concentrations greater than the obtained value in this study. The explanation for this low amount of radon in bottled water can be linked to the processing method employed by the bottled water factories, because radon gas is easily emitted when groundwater is agitated.…”

“…The electronic detector employs the alpha spectrometry method with a bubbling kit. Alpha spectrometry method using RAD7 has widely been used by [5,7,8,2,12]. It can precisely assess the radon levels in a water sample in 20 minutes.…”

“…Water makes up about 60% of body weight in men and 55% in women and for infants it is about 70%-80% [1]. Unrefined water includes a range of pollutants, including biological, chemical, and radioactive contaminants [2]. Most people depend profoundly on groundwater sources as a result of population growth, the contamination of streams, and the inadequacy of the government's potable water supply, numerous individuals have resorted to consuming treated water, such as bottled water and sachet water.…”

“…Recently, with the RAD7 Radon monitoring system, [7] measured radon levels in commercial bottled water and deep well water samples, finding results that were significantly lower than USEPA and WHO recommendations. [2] determined the radon concentrations present in seventeen brands of sachet and bottled water packaged in Ile-Ife, South West Nigeria. [8] assessed the radon concentrations from samples of bottled water available in the Iraqi markets.…”

Radon Levels and Risk Assessment due to its Ingestion and Inhalation from Groundwater of Lapai, North-Central Nigeria

“…This has given rise to an interest in research focusing on drinking water quality in Nigeria. There are quite a good number of researches conducted on the radon concentration levels and its associated health risks due to ingestion and inhalation from portable water in Nigeria (Kolo et al, 2023;Oni et al, 2021;Shu'aibu et al, 2021). However, previous research studies on the water quality level of the Lapai community (the study area) have largely focused on heavy metal assessment and other parameters (Boko et al, 2021;Oladipo et al, 2011).…”
