Successful decommissioning of subsea oil and gas infrastructure requires a safe effective approach to assess manage waste products. These products, often present as scale on internals pipelines, include naturally occurring radioactive materials (NORM) trace metals. Understanding the potential effects these contaminants marine fauna is crucial managing global decommissioning. This review compose...

As information on indoor air quality accumulated* it became apparent that radon and its progeny are invariably present in indoor environments and that concentrations may reach unacceptably high levels. The lung cancer excess anong miners exposed to radon progeny raised concern that exposure to radon progeny might also cause lung cancer in the general population. This presentation first provides...

In this paper, experiences of the last 20 years with PERALS-technique are described. PERALS stands for photo electron-rejecting alpha liquid scintillation. This scintillation technique was developed by Jack McDowell in 1970s and is a powerful analyses many natural nuclides also beta nuclide 90Sr. The principle based on selective extraction radionuclide from water phase means complexing or ion p...

The neutron-deficient Bi188 and Po188 isotopes have been studied by γ-ray spectroscopy using the recoil-decay tagging technique with Argonne Gas-Filled Analyzer. A new 0.25(5)-μs isomeric state a prompt cascade formed 319-, 366-, 462-keV γ rays established on top of (10−) α-decaying isomer in Bi188. first excited (2+) was identified, its excitation energy 242(2) keV continues nearly constant tr...
