Radium uptake in utero

This is a summary of information on a stillborn girl and her mother who had been a radium watch dial painter. Although many dial painters bore children, this is the only example of simultaneous radioactivity determinations in mother and child prior to normal delivery. This case provides an opportunity to assess the degree of transfer of radium to the fetus in utero and may be unique in the study of the placental transfer of radium in humans. Until now only measurements were known of the radium contents of fetuses and unrelated adults. 12 refs.; 3 tabs
