Interplanetary Dust Particles (IDPs) are small grains, generally less than a few hundred micrometers in size. Their main source is the Asteroid Belt, located at 3 AU from the Sun, between Mars and Jupiter. During their flight from the Asteroid Belt to the Earth they are irradiated by galactic and solar cosmic rays (GCR and SCR), thus radionuclides are formed, like ⁴¹Ca and ⁵³Mn. Therefore, ⁴¹Ca (T_1/2 = 1.03 × 10⁵ yr) can be used as a key tracer to determine the accretion rate of IDPs onto the Earth because there are no significant terrestrial sources for this radionuclide. The first step of this study consisted to calculate the production rate of ⁴¹Ca in IDPs accreted by the Earth during their travel from the Asteroid Belt. This production rate, used in accordance with the ⁴¹Ca/⁴⁰Ca ratios that will be measured in snow samples from the Antarctica will be used to calculate the amount of extraterrestrial material accreted by the Earth per year. There challenges for this project are, at first, the much longer time for the flight needed by the IDPs to travel from the Asteroid Belt to the Earth in comparison with the ⁴¹Ca half-life yields an early saturation for the ⁴¹Ca/⁴⁰Ca ratio, and second, the importance of selecting the correct sampling site to avoid a high influx of natural ⁴⁰Ca, preventing dilution of the ⁴¹Ca/⁴⁰Ca ratio, the quantity measured by AMS.
