We describe a new method suitable for the precise and accurate determination of 226Ra in porewater sediment samples using single-collector sector field ICP-MS (ThermoFisher Element XR) equipped with an Apex-Q desolvation device high-sensitivity Jet-X interface. In combination 230Th measurements parallel samples, this allows quantification 226Ra/230Th disequilibria surface cores, thereby enablin...

Kajian dan pemantauan yang dilakukan terhadap taburan penentuan aktiviti keradioaktifan radionuklid semula jadi boleh dijadikan panduan rujukan serta amat berguna terutamanya ketika berlakunya dedahan sinaran tinggi tidak terancang daripada sumber antropogenik kemalangan nuklear global. Sampel tanah permukaan dari 12 lokasi telah dikenal pasti di sekitar kawasan kemudahan repositori diambil unt...

Background: Tea is one of the most popular beverages all over the world which is prepared from the leaves of a shrub camellia sinensis. Eastern Black Sea Region of Turkey which account for around 100% of all tea production in Turkey was among the areas contaminated by Chernobyl accident. Materials and Methods: A comprehensive study was planned and carried out to determine the level of ...

 ABSTRACTBackground: 226 Ra and 228 Ra contents in foodstuffs of Ramsar which is a coastal city in the northern part of Iran were determined by gamma spectrometry. Measurement results together with food consumption rates were used to estimate annual effective dose from  226 Ra and 228 Ra, due to consumption of food stuffs by inhabitants of Ramsar city.Materials and Methods: A total of 33 sample...

In this work a thorough analysis of the vertical distribution natural and artificial radionuclides trace elements in sediment core sample was conducted. A 39 cm length grabbed from deep-sea trench (1540 m depth) southern Samothrace Island, Aegean Sea. The then treated at Hellenic Centre for Marine Research, separated 1cm increment samples, ranging 0cm to cm, dried, milled. first samples also co...

Abstract This paper reports the development and detailed properties of about 13 metric tons gadolinium sulfate octahydrate, $\rm Gd_2(\rm SO_4)_3\cdot \rm 8H_2O$, which has been dissolved into Super-Kamiokande (SK) in summer 2020. We evaluate impact radioactive impurities 8H_2O$ on diffuse supernova neutrino background searches solar observation confirm need to reduce fluorescent by three order...
