Plutonium isotopes 238 Pu , 239 + 240 Pu and 241 Pu in the Baltic Sea ecosystem
Wet and dry atmospheric fallout from nuclear weapon tests is one of the most important sources of plutonium in the Baltic Sea. The other sources: plutonium releases from spent fuel facilities in Sellafield (UK) and Cap de la Hague (France) are less important. Since 26 April 1986 it has been a new source of plutonium – Chernobyl plutonium, which should be taken under note in estimation of its ra...
متن کاملSources of plutonium in the atmosphere and stratosphere-troposphere mixing
Plutonium isotopes have primarily been injected to the stratosphere by the atmospheric nuclear weapon tests and the burn-up of the SNAP-9A satellite. Here we show by using published data that the stratospheric plutonium exponentially decreased with apparent residence time of 1.5 ± 0.5 years, and that the temporal variations of plutonium in surface air followed the stratospheric trends until the...
متن کاملHeat transfer in MHD square duct flow of nanofluid with discrete heat sources
The effect of thermal and solutal buoyancy induced by a discrete source of heat and mass transfer in a square duct under the influence of magnetic field, especially at the turbulent regime for the first time is reported. Al2O3/water nanofluid is used with constant heat flux from three discrete heat sources. In the present study, the effects of Reynolds number (100 to 3000), particle volume frac...
متن کاملHeat Transfer Analysis of Heating Plate with Multiple Heat Sources
Preliminary note 3D numerical study of transient heat transfer phenomenon on a solid plate with complex heat sources has been carried out. In order to validate the chosen numerical model, a set of thermographic measurements have been performed on a heating plate sample. The infrared camera provided a number of thermograms showing the development of transient temperature fields on the plate surf...
متن کاملHormetic modulation of aging and longevity by mild heat stress.
Aging is characterized by a stochastic accumulation of molecular damage, progressive failure of maintenance and repair, and consequent onset of age-related diseases. Applying hormesis in aging research and therapy is based on the principle of stimulation of maintenance and repair pathways by repeated exposure to mild stress. In a series of experimental studies we have shown that repetitive mild...
