The analysis of this radionuclide can be difficult because of the low-level activities involved and its physico-chemical properties (e.g., volatility and multiple oxidation degrees). This study proposes a new method for 129I analysis by ICP-MS/MS, which consists in the extraction of iodine from charcoal by acid digestion followed by purification using a commercial specific resin. This new method allows reaching environmental levels of gaseous 129I near the fuel reprocessing plant of La Hague (France) with a limit of detection of only 2 mBq sample-1. %G English %2 https://irsn.hal.science/irsn-04072741/document %2 https://irsn.hal.science/irsn-04072741/file/Chemicial_treatment_129I.pdf %L irsn-04072741 %U https://irsn.hal.science/irsn-04072741 %~ IRD %~ INSU %~ IRSN %~ CNRS %~ UNIV-AMU %~ CDF %~ INRA %~ CEREGE %~ OSU-INSTITUT-PYTHEAS %~ PSL %~ AGREENIUM %~ INRAE %~ TP %~ CDF-PSL %~ PSEENV %~ SAME %~ SRTE %~ INRAEPACA
