Title: Formerly utilized MED/AEC sites remedial-action program. Radiological survey of Kent Chemical Laboratory, The University of Chicago, Chicago, Illinois, September 7-13, 1977

Abstract

A comprehensive radiological survey was conducted at the Kent Chemical Laboratory at the University of Chicago, Chicago, Illinois. General radiochemistry and/or physics research was performed at this facility during the MED/AEC era in the 1940s. The building is now used as laboratories, offices, and classrooms. The survey was undertaken to determine the location and quantities of any radioactive materials remaining from the MED/AEC operations. Nineteen spots of contamination possibly resulting from MED/AEC occupancy in 12 rooms exceeded the allowable limits for /sup 226/Ra and /sup 239/Pu as given in the ANSI Standard N13.12. Under current use conditions, the potential for radiation exposure to occupants of this building from these sources of contamination is remote. Concentrations of radon daughters in the air of the building were below the limit of 0.01 Working Level above background as given in the Surgeon General's Guidelines. Concentrations of radionuclides in soil samples from near the laboratory were essentially at background levels. The maximum potential dose for external penetrating radiation resulting from exposure to the radioactivity remaining from MED/AEC operations was calculated to be 500 mrem a year, which is equal to the 500 mrem standard for an individual in an uncontrolled area. In order tomore » reduce the potential for radiation exposure, remedial measures such as stabilization of the contamination in place would be applicable as a short-term measure. In order to reduce the risk in the event that building modifications take place in the future, health physics procedures and coverage are recommended. The long-term solution would involve decontamination by removal of the radioactive residues from the 12 rooms or areas where contamination possibly resulting from MED/AEC activities was detected.« less
