Many long-lived radionuclides are present in groundwater at the Nevada Test Site (NTS) as a result of 828 underground nuclear weapons tests conducted between 1951 and 1992. In conjunction with a comprehensive geochemical review of radionuclides (3H, 14C, 36Cl, 99Tc and 129I) that are presumably mobile in the subsurface, we synthesized a body of radionuclide activity data measured from groundwat...

Several directions of the demand for decay data in nuclear astrophysics are discussed for radionuclides near the valley of nuclear stability. The current half-life and gamma-ray intensity evaluation results are presented for some radionuclides of astrophysical interest. An extended list of such nuclides is offered for their nuclear characteristics to be further evaluated by the Decay Data Evalu...

Microspheres loaded with alpha-emitting radionuclides are an alternative to using 90Y to facilitate tumor vascular disruption. Targeting a tumor’s vasculature can be accomplished while minimizing the absorbed dose to healthy tissue by utilizing alpha-emitting radionuclides having limited betagamma emissions.

Introduction Transfer of long lived radionuclides such as Cs, Sr and transuranic elements in contaminated soils at Chernobyl to edible plants were examined. Analysis of radionuclides uptake from contaminated soils by plants is important from the point of view of not only the re-use of the soil, but also the decontamination of the contaminated soils by plants. This is especially true in the envi...

In India, bricks as building materials are mainly prepared by clay using the deposited sediments of rivers, and the radionuclide contents in bricks and brick-making clays should vary with origin and geological condition. Primordial radionuclides in building materials are one of the sources of radiation hazard in dwellings made of these materials. It is important to measure the natural radioacti...

The concentrations of various trace elements and radionuclides have been measured in marine protein concentrates prepared from surface feeding fishes. As with concentrates prepared from benthic fishes, the 210Pb-210Po pair are the most significant radionuclides present. Concentrations of stable Pb, Co and Ag in certain concentrates are sufficiently high to contribute substantially to estimated ...

Introduction: Human has always been exposed to background ionizing radiation. Interaction between ionizing radiation and the biological system can lead to changes in cells or tissues inducing diseases, such as cancer. With this background in mind, this experimental study aimed to evaluate the specific activity of water radionuclides in Kermanshah province, western region of Iran. Material and M...

cesium content and some other more radiologically important mineral elements were measuredby nuclear and non-nuclear analytical methods in iranian daily diets.this study was extended to a few moresimilar functioning elements such as sr, rb, i, k, mg and ca as well. though the 137cs and otherradionuclieds were not measured in these diets under planned regular investigation in this work, but inco...

Actinides have widely entered the environment as a result of nuclear accidents and atmospheric weapon testing. These radionuclides, especially uranium, are outstanding radioactive pollutants, due to their high radiotoxicity and long half-lives. In addition to this, since depleted uranium (DU) has been used in the Balkan conflict in 1999, there has been a concern about the possible consequences ...

We model the heating of a primordial planetesimal by decay of the short-lived radionuclides Al and Fe to determine (1) the time scale on which melting will occur, (2) the minimum size of a body that will produce silicate melt and differentiate, (3) the migration rate of molten material within the interior, and (4) the thermal consequences of the transport of Al in partial melt. Our models incor...
