A search of current nuclear data libraries has identified some inconsistencies in reported gamma line intensities for this decay chain. This paper is a report on the work carried out at BNFL and MAFF to confirm the correct intensities for 234Th and 234mPa.G.A. Sutton and S.T. Napier and ...
In the process, fuel rods, which have been stored for a time to allow short-lived radionuclides to decay, are dissolved and the resulting solution is chemically purified and separated into wastes of different composition and activity. Routine releases from the plants to the environment occur under...
Uranium-236 has a half-life of 2.342×107 years[4] and is not found in significant quantities in nature. The half-life of uranium-236 is too short for it to be primordial, though it has been identified as an extinct progenitor of its alpha decay daughter, thorium-232.[67] Uranium-236...
Uranium-238 is an α emitter, decaying through the 18-member uranium natural decay series into lead-206.[10] The decay series of uranium-235 (also called actino-uranium) has 15 members that ends in lead-207.[10] The constant rates of decay in these series makes comparison of the ratios ...
this decay process. It makesThorium-231 the daughter nuclide of this isotope. Uranium-235 is also known as Actinouranium as it is the parent isotope of the Actinium Series. It producesLeadas the final stable element of this Alpha decay chain. Here is the complete decay series of this ...
(Gschneidner, 1994;Skwarzec, 1997). The isotopes234U and238U occur in the natural radioactive decay chain and238U is the parent nuclide of the uranium-radium series, while235U starts the other natural decay chain, namely uranium-actinium series (Gschneidner, 1994). Uranium isotopes are ...

Evaluation of non-neutron nuclear data for the uranium-238 decay chainIn the present paper the importance of evaluating natural chains will be discussed; some recommended data and related uncertainties are given for the following parameters: half lives, energies and emission probabilities of various ...

Polonium-210 arises from lead-210 decay and is a widespread alpha-emitting radionuclide. It seeks soft tissue and has the potential to accumulate in the food chain. Caribou, wolves and other wildlife may become exposed to enhanced levels of these two uranium-series radionuclides if the proposed ...
