Abstract A reconstruction of historical discharges 236 U into the Northeast Atlantic Ocean by nuclear installations is presented. The reprocessing facilities Sellafield (SF), Great Britain (GB) and La Hague (LH), France potentially also fuel processing installation Springfields (SP), GB represent main contributors in Ocean. Because data on releases lacking, from SP SF are estimated based U‐isotopic systematics found LH. resulting indicates that, until 2013, a total (95 ± 32) kg was...
In recent years, trace concentrations of H 2 S have been measured employing a fluorescence analytical method. Automatization the method caused enhancement its capacity. Thus it became possible to observe variations concentration during days, months, and years at different sampling sites. The obtained data showed that swamps tidal flats are natural sources S. Their contributions atmospheric sulfur cycle compared with those volcanic activity Etna (Italy) anthropogenic in environment Frankfurt...

Longitudinal electron-beam diagnostics play a critical role in the operation and control of x-ray free-electron lasers, which rely on parameters such as current profile, longitudinal phase space, or slice emittance particle distribution. On one hand, femtosecond-scale electron bunches produced at these facilities impose stringent requirements resolution achievable with diagnostics. other, research development novel accelerator technologies beam-driven plasma-wakefield accelerators (PWFA)...

In this study we present new seawater data of 236U and 238U sampled in the North Sea 2010. The has been is still receiving a considerable input anthropogenic radionuclides from nuclear reprocessing facilities located La Hague (France) Sellafield (Great Britain). It therefore represents an important source region for oceanographic tracer studies using transient signal 236U. A proper knowledge sources essential prerequisite such studies. set presented covers transition regions to Atlantic...
