A detailed and comprehensive map of the distribution patterns for both natural and artificial radionuclides over Antarctica has been established. This work integrates the results of several decades of international programs focusing on the analysis of natural and artificial radionuclides in snow and ice cores from this polar region. The mean value (37±20 Bq m^-2) of ²⁴¹Pu total deposition over 28 stations is determined from the gamma emissions of its daughter ²⁴¹Am, presenting a long half-life (432.7 yrs). Detailed profiles and distributions of ²⁴¹Pu in ice cores make it possible to clearly distinguish between the atmospheric thermonuclear tests of the fifties and sixties. Strong relationships are also found between radionuclide data (¹³⁷Cs with respect to ²⁴¹Pu and ²¹⁰Pb with respect to ¹³⁷Cs), make it possible to estimate the total deposition or natural fluxes of these radionuclides. Total deposition of ¹³⁷Cs over Antarctica is estimated at 760 TBq, based on results from the 90-180° East sector. Given the irregular distribution of sampling sites, more ice cores and snow samples must be analyzed in other sectors of Antarctica to check the validity of this figure.
