Abstract:
Abstract There is little available information on the radioactivity concentrations in the thermal and drinking water sources in North Vietnam. In the current study, the gross alpha and gross beta activity concentrations were determined in 8 water sources in the area. The average activities of gross alpha and beta in the 8 sources are 38.7 mBq L− 1 and 88.0 mBq L− 1. These activity concentrations are lower than WHO recommendations for drinking water. In this study, the gross alpha and gross beta show a weak correlation.

Abstract:
Measurement of gross alpha and beta radioactivity in drinking water is an important screening method for assessing radiological water quality. In recent years, the trend of using bottled water has expanded significantly, therefore monitorization of the level of radioactivity has become essential. The present study aimed to evaluate the total radioactivity of bottled mineral water samples from different regions of Transylvania, Romania over a 6 year-period (2017-2022). The obtained results indicate concentrations of gross alpha and beta activities ranging from 0.0057 to 0.0801 Bq/L with a mean value of 0.0383 Bq/L for gross alpha activity, and between 0.0929 Bq/L and 0.7953 Bq/L with a mean value of 0.4415 Bq/L for gross beta activity. The radioactivity values of bottled mineral waters were situated within the permitted levels regulated by WHO, with reference values of 0.5 Bq/L for gross alpha activity and 1 Bq/L for gross beta activity, respectively. The obtained values were also within the limits recommended by the Council Directive 2013/51/ EURATOM, of 0.1 Bq/L for gross alpha activity and 1 Bq/l for gross beta activity, respectively. According to the results of this study, the investigated bottled mineral waters can be considered radiologically safe for consumption.

Abstract:
Water intended for drinking purposes has to be analyzed first for gross alpha/beta activity according to national and international standards and recommendations. According to Albanian legislation, Article 6, the gross alpha/beta radioactivity concentration in water, should be below the level of 0.1 Bq/L and 1 Bq/L respectively for human consumption. Our laboratory participated in an interlaboratory comparison organized by IAEA Terrestrial Environmental Laboratory under suggestion of ALMERA members. Proficiency Test among environmental radioactivity monitoring laboratories for the determination of gross alpha/beta activity concentration in drinking water and contaminated surfaces (2018, 2020). Independent standard methods were used for the reference value determination. Each sample was pretreated on site with nitric acid until reaching a pH level below 2. By creating relatively non-polar surfaces, this procedure avoids a loss of radionuclide fractions due to absorption into the walls of the containers.The Gross alpha/beta activity measurements were done using gas-flow proportional counter (GPC) method. The total dissolved solids should not exceed a surface density of 5 mg/cm2 for gross alpha determination and 10 mg/cm2 for gross beta determination The performance of participating laboratories was evaluated with respect to the reference values using relative deviations. The results presented from our laboratory in both inter comparisons (IAEA-TEL-2018-03) and (IAEA-TEL-2020-03) were all acceptable. The laboratory for the measurement of gross alpha/beta radioactivity and our Institute as a part of Tirana University is in the process of accreditation, so far the participation in the inter comparisons exercise is very important.

Abstract:
The objective of the present study is the screening of the gross alpha and gross beta activity of some building materials commercialized in Saudi Arabia. The measurements were carried out using a gas flow proportional counter. The study has shown that the gross alpha activity ranged between 0.21 and 8.27 Bq/kg with an average activity of about 1.96 Bq/kg, whereas the gross beta activity ranged between 6.47 and 276.47 Bq/kg with an average activity of about 65.27 Bq/kg. The obtained values of gross alpha and beta activities are in the worldwide range and no significant activity was observed that accentuate the attention, which show that no radiation risks come from these building materials and, therefore, from their origin areas.

Abstract:
Over the past decade, radioactivity in drinking water has become a matter of urgent concern following reports from various scientific researches. The rapid urbanization and increase in population of Ogwashi-Uku has culminated in the increase for demand of safe and potable water hence the need for this study. A total of 10 samples were collected from the study location. Standard methods for determination of gross alpha and gross beta activity concentrations in the water samples were deployed. The measured gross alpha activity concentrations for all water samples are below 0.1 Bq/L while the measured gross beta activity concentrations in all water samples collected are lower than 1.0 Bq/L permissible limit. The mean annual dose equivalent in all the water samples for gross alpha and gross beta activity is lower than 0.1 mSv recommended dose for radionuclides in water, hence the life cancer risk assessment showed lower values, indicating the water is safe for drinking. The purpose of this study is to assess the concentration of gross alpha and beta activity levels of drinking water from hand-dug reservoirs in Ogwashi-Uku, Delta State in order to offer a scientific basis for making decisions regarding mitigating radioactive pollution and also to ensure the safety of drinking water and public health.

Abstract:
The gross alpha and beta activity concentrations of eighteen water samples, consisting of boreholes and Hand-dug wells from Sabon Gari Local government area of Kaduna StateNigeria have been analyzed using, the potable single channel gas free MPC-2000B-DP detector. The results show that alpha and beta activity concentrations range from 0.96 × 10-2 Bq/L to 47.00 ×10-2 Bq/L and from 0.309 × 10-2 Bq/L to 310.40 × 10-2 Bq/L, for gross alpha and gross beta respectively. It is observed that in the overall samples, the gross alpha activity concentrations were below the 0.5 Bq/L maximum allowable limits for drinking water as recommended by World Health Organization (WHO). However, for the gross beta activity concentration, eleven (11) percent of the samples, have their activity concentrations greater than the 1.0 Bq/L maximum allowable limits for drinking water as recommended by the WHO. This high beta activity concentration in these areas might be due to the waste generated from industries and hospitals or as a result of the nature of farming activities occurring in the areas. Largely, results obtained are seen to be in agreement with reports from other authors within and outside Nigeria.

Abstract:
Dans l'analyse des émetteurs alpha et beta dans l'eau par scintillation liquide, la problématique de la discrimination des rayonnements se pose afin d'atteindre les limites de détection souhaitées. Dans le cas rare ou les énergies permettent une discrimination, nous avons mis en place un protocole d'analyse simultanée tritium/alpha sur des frottis. A l'aide d'une méthode a trois fenêtres il permet d'atteindre les limites de détection de 0,4 Bq/cm2 en tritium et de 0,04 Bq/cm2 en alpha.De façon générale, aucune distinction entre les spectres n'est possible et un ajustement du fond sous le pic alpha ne permet pas d'atteindre les limites de détection définies par les normes. Cependant le processus physique de scintillation permet une distinction des rayonnements, phénomène utilise par certains appareils, ceux-ci proposent donc le réglage par l'utilisateur d'un paramètre discriminant seuil. Nous avons développé un protocole de réglage permettant de reconstituer les spectres alpha et beta discrimines au mieux, rendant accessible une limite de détection de 0,03 Bq/L en alpha.Nous avons par ailleurs développé une approche innovante utilisant un détecteur en coïncidence dont les photomultiplicateurs sont connectes directement a une carte numérique d'acquisition. Chaque impulsion numérisée est ensuite traitée selon plusieurs critères simultanément, à la place des deux habituels. Aucun ne permet a lui seul d'obtenir une discrimination selon un seuil unique, mais la distribution des évènements dans chaque spectre est différente : un fenêtrage des évènements alpha permet d'atteindre une limite de détection de 0,2 Bq/L, quatre fois moindre que par une discrimination en énergie seule.

Radiological effects on population and environment due to fracking unconventional hydrocarbons is given in this study. Evaluation on environmental effects concerning extraction process is given. Effects on fauna and humans during fracking process, including on air, water and soil, are mentioned. Unconventional oil and gas extraction generates Natural Occurring Radioactive Materials (NORM); their associations to radiological aspects are comment. Our environmental radiological baseline studies at three prospecting fracking zones in Mexico showed no radiological hazard to population. The natural gamma radioactivity before fracking had a maximum equivalent dose rate of 1.83 mSv a−1, in the low value of the acceptable background interval (1–13) mSv a−1 stated by UNSCEAR. The 226Ra and 228Ra maximum concentration obtained in soil (59.2 ± 3.6 and 38.5 ± 5.0 Bq kg−1, respectively) for this baseline are both in the average global-interval concentration reported by UNSCEAR; gross alpha and gross beta in water were all below the suggested limits by the World Health Organization of 0.5 and 1.0 Bq L−1, respectively, for drinking water. An important conclusion is that water stress is an important issue before considering fracking activities in Mexico.

Abstract Ever since the discovery that penicillin inhibits bacterial cell wall synthesis, developing equivalent agents to target the fungal cell wall has been a focus in antifungal drug development. Because the cell wall is essential to the vitality of fungal organisms and because its components are absent in the mammalian host, the fungal cell wall represents an ideal target for antifungal compounds. With considerable variation among different species, the gross macromolecular components of the cell wall of most fungi include chitin, alpha- or beta-linked glucans and a variety of mannoproteins. The dynamics of the fungal cell wall are closely coordinated with cell growth and cell division, and its predominant function is to control the internal turgor pressure of the cell. Disruption of the cell wall structure leads to osmotic instability, and may ultimately result in the lysis of the fungal cell. Systemic antifungal agents directed against or involving the major constituents of the fungal cell wall include the new class of echinocandin lipopeptides and the nucleoside-peptide antibiotic nikkomycin Z.

Abstract As a screening procedure, gross alpha and gross beta activity have been developed to determine whether further analysis of water samples related to specific radionuclide is necessary. In China, the determination of gross alpha and gross beta in drinking water was generally based on the HJ standard method: HJ 898-2017, water quality — determination of gross alpha activity — thick source method, and HJ 899-2017, water quality — determination of gross beta activity — thick source method. In this study, 15 water samples from Bahe river in Chan Ba region of Xi’an in China, were pretreated and analyzed by BH1216-III low background alpha and beta scintillation counter. The water samples were collected nearby residential area, wetland park, water conservation district and urban sewage treatment plant as well as other important locations which probably influence on the radioactivity level. The values of the activity concentrations of the gross alpha and beta measured in the water samples ranged from less than LD to 0.183Bq/L with a mean of 0.077Bq/L and 0.073–0.151Bq/L with a mean 0.102Bq/L respectively. All values of samples were lower than the limit level of 0.500Bq/L for gross alpha and 1.000Bq/L for gross beta, indicating that the radioactivity level in Bahe water between Chan Ba region of Xi’an is basically within the normal environmental background.

Abstract Radionuclide activity concentration in drinking water cannot be measured directly at normal conditions. The water samples need to be concentrated under mild boiling conditions according to relevant standards. However, the method takes too long a time that it can hardly handle emergency measurements. A fast concentration method based on vacuum and low temperature is proposed in this study. The method was validated in the gross alpha and gross beta measurement of drinking water samples. The sample preparation time based on liquid scintillation counting (LSC) is only about 80 minutes, and the recovery percent of alpha certified sample is more than 80%, and that of beta certified sample is more than 90%. The experimental results show that the method can be used not only for the preparation of samples of gross alpha and gross beta measurement, but also for the preconcentration of specific nuclides measurement.

The evaluation of radioactivity levels was performed on milk samples collected biannually for a period of 10 years (2012-2021) from two Central Romanian counties, Sibiu and Alba. The radioactivity concentrations in milk samples originated from Sibiu varied from 0.028�0.001 Bq/L to 0.347�0.017 Bq/L, from 24.017�0.977 Bq/L to 65.403�6.281 Bq/L, from 0.090�0.010 Bq/L to 0.110�0.010 Bq/L, from 0.085 to 0.110 Bq/L, for gross alpha, gross beta, 137Cs and 90Sr, respectively. The radioactivity concentrations in milk samples originated from Alba varied from 0.056�0.003 Bq/L to 0.347�0.020 Bq/L, from 23.499�0.785Bq/L to 59.483�2.881 Bq/L, from 0.095�0.010 Bq/L to 0.110�0.011 Bq/L, from 0.088�0.009 Bq/L to 0.101�0.009 Bq/L, for gross alpha, gross beta, 137Cs and 90Sr, respectively. The mean values in tested samples from Sibiu/Alba were 0.163�0.006 Bq/L/0.194�0.008 Bq/L for gross alpha, 41.232�3.360 Bq/L/ 39.285�3.230 Bq/L for gross beta, 0.100�0.010 Bq/L/ 0.098�0.009 Bq/L for 137Cs, and 0.093�0.009 Bq/L/ 0.094�0.009 Bq/L for 90Sr. No statistically significant differences between values in tested milk from Sibiu and Alba counties were found. In the absence of WHO and UNSCEAR recommendations on limit values for alpha and beta raw activity levels in milk, but in accordance with the recommendations of Directive 52/2016, 137Cs and 90Sr radionuclides of the tested milk samples were within the maximum permitted levels and have no side effects on health.
