  1. Derived intervention levels for the Costa Rican diet.

    Article - En anglais

    A theoretical analysis for the determination of particular derived intervention levels DILs for Costa Rica is presented.

    DILs for 15 radionuclides for the Costa Rican diet are calculated.

    Assuming all foodstuffs are contaminated only with 137Cs and a total annual intake of 355 kg y-1 intead of the 550 kg y-1 proposed by the WHO, the corresponding DIL is approximately 2000 Bq kg-1.

    Four possible radionuclide combinations studied that might result from a nuclear accident are :

    • 137Cs and 134Cs ;

    • 137Cs, 134Cs, 89Sr and 90Sr ;

    • 137Cs, 134Cs, 131I, and 133I ;

    • 137Cs, 134Cs, 89Sr, 90Sr, 131I, 133I and 239Pu.
