Concentration of inhaled cerium-144 in pulmonary lymph nodes of human beings

Abstract

IN the course of an investigation of fission products deposited in human lungs1, we have also measured the radioactivity of pulmonary lymph nodes. In most cases investigated so far, the amounts of fission products found were too small to permit deductions about concentration of these substances in the lymph nodes. However, in some cases larger activities were observed and the occurrence of a concentration process could be clearly recognized. © 1961 Nature Publishing Group.
