The radioactivities of eight main foodstuffs were investigated during 1985-1994 to evaluate the annual intake from the ingestion of <sup>137</sup>Cs and <sup>90</sup>Sr for the residents of Taiwan. The evaluation of annual intake was based on the results of radiochemical analysis of <sup>90</sup>Sr and gamma-ray spectrometry of <sup>137</sup>Cs as well as annual consumption rates of those foodstuffs in Taiwan. The annual intake of <sup>90</sup>Sr and <sup>137</sup>Cs per capita is 13 and 60Bq, respectively. Among the eight foodstuffs, fruit contributed the most to the annual intake of <sup>90</sup>Sr, vegetable second, rice the third and egg the least. For <sup>137</sup>Cs, rice contributed the most, then fruit, meat the third and flour the least. Based on the new conversion factors from ICRP 60, the annual committed effective doses of Taiwanese due to the ingestion of radionuclides <sup>90</sup>Sr and <sup>137</sup>Cs were estimated to be 3.7×10<sup>-7</sup> and 7.8×10<sup>-7</sup>Sv, respectively.
