10Be and dust
The 10Be flux at a given geographical location consists of recent atmospherically produced 10Be and of recycled 10Be, which is brought in with dust particles. The importance of the latter fractionExpand

On the analysis of iodine-129 and iodine-127 in environmental materials by accelerator mass spectrometry and ion chromatography.
Based on a review of literature about the abundances of 129I (T1/2 = 15.7 Ma) in the environment we show that there is a severe lack of knowledge, in particular about natural, pre-nuclear levels.Expand

Determination of 129I/127I in aerosol samples in Seville (Spain).
In this work we present results of the (129)I/(127)I ratio in aerosols of Seville, Southwest of Spain (37.4 degrees N,6 degrees W). A radiochemical method is applied to extract the iodine from theExpand
