The concentration of <sup>134</sup>Cs and <sup>137</sup>Cs was estimated in different pathways consisting of the ingestion of plants, milk, and meat. The highest air concentration has been determined at 65 m distance from the core of the reactor. The maximum concentration passed off without delay simply after the accident in various directions. Local meteorological information such as average wind velocity and wind frequency were analyzed. Considering all directions, the highest concentration has been observed in the “S” direction. The concentrations of <sup>134</sup>Cs and <sup>137</sup>Cs were determined in ground, vegetation, milk and meat. The concentration of <sup>137</sup>Cs is investigated to be higher than the <sup>134</sup>Cs. The concentration of <sup>134</sup>Cs and <sup>137</sup>Cs was found to be lower in vegetation, milk, and meat than that of ground concentration. Overall, in this study, the concentration in meat has been investigated to be lower. In case of a reactor accident, the concentration assessment due to the ingestion of vegetables, milk, and meat will be a valuable guide for insuring radiological protection across the research reactor at AERE, Savar, Bangladesh.展开更多
