A mobile human radioactivity counter and medical van was designed to reduce the cost of whole body counting and to increase general health surveillance at the national reactor testing station by bringing laboratory facilities to the work areas. The van is scheduled at each of the main reactor areas on a routine basis, which eliminates the employee from having to travel up to 70 miles for monitoring checkups. The whole-body counter utilizes the minimal shielding concepts as well as the rotational counting technique that permits the simultaneous quantification and localization of gamma-emitting nuclides from a single count. Calibration of the counter was accomplished by using human volunteers who had ingested single radionuclides. The detection limit for most gamma-emitting nuclides is well below the maximum permissible body burdens recommended by the icrp. Over 5000 individuals have received whole-body analyses, laboratory and x-ray examinations since this van was put into operation. This mobile instrument has proven to be an effective and economical addition to the health services program.
