Aerial Radiological Surveys of Rockwell International Facilities, Canoga Park, California. Dates of Surveys: June and July 1978

摘要

Aerial radiological surveys were conducted over two facilities. The first survey, conducted on 26 and 27 June 1978 at an altitude of 46 m, was over the Headquarters Facility in urban Canoga Park, California. The second, on 29 and 30 June and 5 to 8 July 1978, was flown at 61 m altitude over the Santa Susana Field Laboratories in the Santa Susana Mountains, about 15 km west-northwest of the Headquarters. Twenty sodium iodide detectors were mounted on a helicopter. Enhanced gamma exposure rate levels were observed during both surveys; these levels could be attributed to industrial operations at the survey sites. (ERA citation 05:027715)
