Carbon-containing gases in the atmosphere are important for the study of carbon cycle dynamics and anthropogenic influence on these environmental processes. Radiocarbon analysis is an excellent tool for studying sources of these gases and t...
Physics-informed deep learning for rapid marine radionuclide dispersion forecasting in nuclear emergency response [0.03%]
Zhiqiang Cui,Xiong Wu,Yonghong Liu et al.
Zhiqiang Cui et al.
In the event of a severe nuclear accident at a coastal nuclear power plant, the rapid and accurate assessment of radionuclide dispersion in surrounding coastal waters is critical for effective emergency response. To overcome the inherent la...
Tracing submarine groundwater discharge in a semi-enclosed bay using pulsed ionization chamber radon detector [0.03%]
Chunqian Li,Shibin Zhao,Lu Cao et al.
Chunqian Li et al.
Natural occurring radon (222Rn, t1/2 = 3.8 d) is a powerful tracer for investigating submarine groundwater discharge (SGD) and other hydrological and oceanographic processes. Continuous 222Rn measurement approach is essential but remains in...
