The full relativistic treatment improves calculation of the magnetic moment. In Dy2Fe14B, the total magnetic moment is 12.75 mu(B)/f.u., which is in good agreement with experimental data, 11.3 mu(B)/f.u. The magnetic moment calculation obtained by using LCPAO is suitable for large-scale systems with rare-earth elements. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3068458]“
“The manufacture Selleckchem Selisistat and use of radium in the early to mid-20th century within industrial, medicinal and recreational products have resulted in a large number of contaminated sites across a number of countries with notable examples in the USA and Europe. These sites, represent a significant

number of unregulated sources of potential radiological exposure that have collectively and hitherto not been well characterised. In 2007, the Radioactive Contaminated Land (RCL) Regulations came into force in the UK, providing the statutory guidance for regulators to classify and deal with RCL Here AZD8186 datasheet we report on results derived from digestion experiments to estimate committed effective dose, a key aspect of the RCL Regulations, from the ingestion of radium contaminated sources that can be found in the environment. This case study includes particles, clinker and artefacts that arise from past

military activities on a site that was once an airfield at Dalgety Bay on the Firth of Forth, UK. Since 2011 the number of radium contaminated finds has increased by one order of magnitude on the foreshore areas of Dalgety Quizartinib concentration Bay. The increase in finds may in large part be attributed to a change in monitoring practice. A subsample of sixty sources was selected, on the basis of their activity and dimensions, and subjected to digestion in simulated stomach and lower intestine solutions. The study demonstrated that more radium-226 (Ra-226) and lead-210 (Pb-210; driven by Polonium solubility) are dissolved from sources in artificial ‘stomach’ solutions compared with

‘lower intestine’ solutions. The combined ‘gut’ solubility for 226Ra and apparent Pb-210 varied from less than 1% to up to 35% ICRP 72 conversion factors were used to convert the activities measured in solution to committed effective dose. A little over 10% of the sources tested dissolved sufficient radioactivity to result in 100 mSv committed effective dose to an infant. Using the solubility of 35% as a worst case, minimum source activities necessary to deliver 100 mSv to the full age ranie of users of the foreshore were estimated. All the estimated activities have been detected and recovered through routine monitoring. (C) 2013 Elsevier Ltd. All rights reserved.”
