  abstract = {{A} new procedure allowing the sequential extraction of {R}a, {N}d, {T}h, {P}a and {U} from the same initial natural sample (sea or river waters, particles, sediments, rocks) is proposed. {E}xtraction recoveries were better than 90%. {P}rocedural blanks ranged from 80 pg (for {N}d) to below 1 fg, the detection limit of the {MC}-{ICP}-{MS} used (for {P}a); all were negligible compared with the amounts of elements currently determined. {B}ased on classical anionic resins attached to a peristaltic pump allowing precise flow rate control, this procedure allowed a consequent reduction of the sample size, which improved the sampling resolution and reduced the sampling cost. {I}t also ensured a better consistency of the samples for the five tracers.},
