description Publicationkeyboard_double_arrow_right Article , Other literature type 2023Publisher:Elsevier BV M. M. Mahfuz Siraz; M. S. Alam; Jubair Al Mahmud; Sudeb Chandra Das; Jannatul Ferdous; Z. Hossain; Sopan Das; Mayeen Uddin Khandaker; D.A. Bradley; Shinji Tokonami; Selina Yeasmin;Le radon est un agent cancérigène naturel qui présente un risque grave pour la santé lorsqu'il est inhalé ou ingéré en quantités importantes. L'eau de la rivière Padma sera utilisée comme liquide de refroidissement tertiaire pour la « centrale nucléaire de Rooppur » qui sera bientôt mise en service. Par conséquent, il est important d'évaluer l'état radiologique de la rivière avant la mise en service de cette centrale électrique. Par conséquent, pour la première fois, 25 échantillons d'eau ont été prélevés à divers endroits de la rivière Padma et analysés pour la concentration de radon à l'aide du dispositif de surveillance du radon RAD H2O (DURRIDGE). Les concentrations de radon ont été trouvées dans la plage de 0,077 ± 0,036 à 0,494 ± 0,211 Bq/L avec une moyenne de 0,250 ± 0,093 Bq/L. Toutes les concentrations se sont avérées inférieures aux limites recommandées de l'OMS (100 Bq/L) et de l'USEPA (11,1 Bq/L). La dose efficace annuelle moyenne due à l'exposition au radon par inhalation et par ingestion était de 0,638 μSv/an et 0,629 μSv/an, respectivement, ce qui était bien inférieur à la dose efficace annuelle recommandée par l'OMS (0,1 mSv/an). Étant donné que le Bangladesh n'a pas de limite nationale de sécurité pour le radon dans l'eau, cette étude pionnière fournit des données de base sur les niveaux de radon pour l'environnement autour de la centrale nucléaire de Rooppur. El radón es un agente cancerígeno natural, representa un grave peligro para la salud cuando se inhala o ingiere en cantidades significativas. El agua del río Padma se utilizará como refrigerante terciario para la 'Central Nuclear de Rooppur' que se pondrá en servicio próximamente. Por lo tanto, es importante evaluar el estado radiológico del río antes de la puesta en marcha de esta central eléctrica. Por lo tanto, por primera vez, se recolectaron 25 muestras de agua de varias ubicaciones del río Padma y se analizaron para determinar la concentración de radón utilizando el dispositivo de monitoreo de radón RAD H2O (DURRIDGE). Las concentraciones de radón se encontraron en el rango de 0.077 ± 0.036 a 0.494 ± 0.211 Bq/L con una media de 0.250 ± 0.093 Bq/L. Se encontró QUE todas las concentraciones estaban por debajo de los límites recomendados de la OMS (100 Bq/L) y USEPA (11.1 Bq/L). La dosis efectiva anual media debido a la exposición al radón a través de las vías de inhalación e ingestión fue de 0,638 μSv/a y 0,629 μSv/a, respectivamente, que estaban muy por debajo de la dosis efectiva anual recomendada por la OMS (0,1 mSv/a). Dado que Bangladesh carece de un límite nacional de seguridad del radón en el agua, este estudio pionero proporciona datos de referencia sobre los niveles de radón para el medio ambiente alrededor de la central nuclear de Rooppur. Radon is a naturally occurring carcinogenic agent, poses a serious health hazard when inhaled or ingested in significant amounts. The water of the Padma river will be used as a tertiary coolant for the soon-to-be-commissioned 'Rooppur Nuclear Power Plant'. Hence, it is important to assess the radiological status of the river prior to the commission of this power plant. Therefore, for the first time, 25 samples of water were collected from various locations of the Padma River and analyzed for radon concentration using the RAD H2O (DURRIDGE) radon monitoring device. The radon concentrations were found in the range from 0.077 ± 0.036 to 0.494 ± 0.211 Bq/L with a mean of 0.250 ± 0.093 Bq/L. All the concentrations were found to be below the recommended limits of WHO (100 Bq/L) and USEPA (11.1 Bq/L). The mean annual effective dose due to the radon exposure via inhalation and ingestion pathways were 0.638 μSv/y and 0.629 μSv/y, respectively, which were all well below the annual effective dose recommended by WHO (0.1 mSv/y). Since Bangladesh lacks a national safety limit of radon in water, this pioneering study provides baseline data on radon levels for the environment around Rooppur Nuclear Power Plant. الرادون هو عامل مسرطن يحدث بشكل طبيعي، ويشكل خطرًا صحيًا خطيرًا عند استنشاقه أو تناوله بكميات كبيرة. سيتم استخدام مياه نهر بادما كمبرد ثالث لـ "محطة روبور للطاقة النووية" التي سيتم تشغيلها قريبًا. وبالتالي، من المهم تقييم الحالة الإشعاعية للنهر قبل بدء تشغيل محطة الطاقة هذه. لذلك، ولأول مرة، تم جمع 25 عينة من المياه من مواقع مختلفة من نهر بادما وتحليلها لتركيز الرادون باستخدام جهاز مراقبة الرادون RAD H2O (DURRIDGE). تم العثور على تركيزات الرادون في حدود 0.077 ± 0.036 إلى 0.494 ± 0.211 Bq/L بمتوسط 0.250 ± 0.093 Bq/L. تم العثور على جميع التركيزات أقل من الحدود الموصى بها لمنظمة الصحة العالمية (100 Bq/L) ووكالة حماية البيئة الأمريكية (11.1 Bq/L). كان متوسط الجرعة الفعالة السنوية بسبب التعرض للرادون عبر مسارات الاستنشاق والابتلاع 0.638 ميكروسيفرت/سنة و 0.629 ميكروسيفرت/سنة، على التوالي، والتي كانت جميعها أقل بكثير من الجرعة الفعالة السنوية التي أوصت بها منظمة الصحة العالمية (0.1 ميكروسيفرت/سنة). نظرًا لأن بنغلاديش تفتقر إلى حد أمان وطني للرادون في الماء، فإن هذه الدراسة الرائدة توفر بيانات أساسية عن مستويات الرادون للبيئة المحيطة بمحطة روبور للطاقة النووية.

M. R. Jahangir;The world is confronted with one of the most difficult tasks of the twenty-first century, satisfying society’s expanding food demands while causing agriculture’s environmental impacts. Rice security is the food security for South Asian countries. Rice production requires a large amount of water and fertilizer, especially nitrogenous fertilizer, where urea works as the primary source of nitrogen (N). Different biogeochemical conditions, such as alternate wetting and drying (AWD), intermittent drainage, agroclimatic conditions, oxic-anoxic condition, complete flooded irrigation,. have severe impacts on GHGs emission and nitrogen use efficiency (NUE) from rice fields. For sustainable production, it is a must to mitigate the emissions of GHGs and increase NUE along with cost minimization. But analytically accurate data about these losses are still not quantifiably justified. In this chapter, we will show the proper use of the measured data with suitable results and discussions to recommend the future cultivation system of rice for sustainable production.
