A Calculation of Effective Dose Equivalent from Data of Environmental Monitoring around the Karlsruhe Nuclear Research Center
Lee, Chang-Woo;Lee, Jeong-Ho;Wicke, A.;
ABSTRACT
The dose calculations were carried out using environmental montoring data around Karlsruhe Nuclear Research Center(KfK). Ingestion of plant foods was the most important pathway, and the K-40 and Pb-210 natural radioisotopes in food were the most effective radiation source to man. The dose received from artificial nuclides were mostly emitted by gamma irradiation of Cs-134 and Cs-137 deposited on the ground. The effective dose equivalent in the KfK environment was far less than the dose equivalent limit recommended by ICRP.
