SERIES TITLE Health Effects of Exposure to Internally Deposited Radioactivity: 
             Other Radioelements and Circumstances of Exposure Subseries 
 
 
INCLUSIVE DATES ca. 1945 1985 
 
 
ARRANGEMENT Subject Numerical (case files) 
 
 
VOLUME approximately 5 cubic feet 
 
 
DESCRIPTION 
These records were created or collected by the staff of the Center for Human Radiobiology 
in the course of dosimetric work on persons exposed to a variety of radioactivity 
including incidental exposure, self employment, or medical procedures that involved 
use of a radiographic contrast medium called thorotrast. They include records of the 
measurement of radioactivity in the people and their excreta, plus any medical information 
that the subjects may have authorized for release to Argonne. Such radioelements and 
substances as protactinium, thorotrast, plutonium, americium, and strontium were among 
those included in this work. They also include any past records 
pertinent to the subject matter (e.g., the radioactivity associated with thorotrast).
