| In 1979, the Department of Energy (DOE) launched a major effort, called the
Off-site Radiation Exposure Review Project (ORERP). The principal objective
of the ORERP was to collect, organize, and analyze all relevant documents
and data pertaining to fallout and resultant exposure to off-site population
groups in the vicinity of the Nevada Test Site. Since that time, more than
200,000 documents have been amassed and exposure estimates for discrete
fallout events have been derived from empirical measurements and
computer-projection models. The total collective external exposure from 1951
through 1975 for all communities was estimated to be 86,000 person-R, with
the greatest exposures occurring in Saint George, Utah; Ely, Nevada; and Las
Vegas, Nevada.
One of the results of the project was a set of data files relating to fallout
transport and population demographics. These dose estimation models,
included in CEDR, are the Town Data Base file (TOWNDB), the County Data
Base file (CNTYDB) and the Lifestyle Survey Data Base files (LFSDEMOG and
LFSFARM). |
