Movement of ¹³⁷Cs across Surviving Intestinal Segments in Vitro

Summary

A net transfer of caesium-137 from the mucosal to the serosal side of surviving intestinal segments did not occur when in vitro procedures were used. However, a net transfer of ¹³⁷Cs occurred from the serosa to the mucosa, suggesting the presence of a mechanism for the transfer of ¹³⁷Cs in this direction. The importance of this mechanism is not known.
