Induced Radioactivity and Transmutation

Predicting Induced Radioactivity at High Energy Accelerators

Partitioning and Transmutation

Spent fuel from nuclear power plants contains long-lived radionuclides, which are the mainreason for its long storage time. These long-lived elements can be converted into short-livedor stable nuclides by neutron irradiation. For this transmutation process to be successful, agood separation of the long-lived elements, the actinides, from the rest of the waste must beensured....

Radioactivity of Tobacco Leaves and Radiation Dose Induced from Smoking

The radioactivity in tobacco leaves collected from 15 different regions of Greece and before cigarette production was studied in order to find out any association between the root uptake of radionuclides from soil ground by the tobacco plants and the effective dose induced to smokers from cigarette tobacco due to the naturally occurring primordial radionuclides , such as 226Ra and 210Pb of the ...

Partitioning and Accelerator Driven Transmutation

It had previously been shown that 2,6-di(5,6-dialkyl-1,2,4-triazin-3-yl)pyridines extract Am(III) selectively over Eu(III), giving a separation factor of 100-120. In this work a more detailed study of the distribution equilibria was made. If not given otherwise, 2,6-di(5,6-dipropyl-1,2,4-triazin-3yl)pyridine (= B) was taken as a representative of the title extractant class and a mixture of bran...

Anomaly Mediation and Dimensional Transmutation

We show how a sparticle spectrum characteristic of anomaly mediation can arise from a theory whose Lagrangian contains no explicit mass scale. The scale of supersymmetry breaking is governed by the gravitino mass, which is the vacuum expectation value of the F -term of the conformal compensator field, and the tachyonic slepton problem is resolved by the breaking of a U ′ 1 gauge symmetry at a s...
