This work was performed by EG&G for the United States Department of Energy, Division of Operational and Environmental Safety, and the United States Nuclear Regulatory Commission, under Contract No. EY-76-C48-il83.
ABSTRACT An airborne radiological survey of a 2146 km2 area surrounding the Edwin 1. liatch Nuclear Plant was made 28-31 March 1977. Detected radioisotopes, and their associated gamma ray exposure rates, were consistent with that expected from the normal background emitters.
Count rates observed at 152 m altitude are converted to equivalent exposure rates at 1 m above the ground, and are presented in the form of an isopleth map.
Exposure rates measured with small portable instruments and soil sample analysis showed agreement with the l
i airborne data.

1.0 INTRODUCTION
The United States Department of Energy (DOE) maintains an aerial surveillance operatiorr called the Aerial Measuring Systems (AMS),* which is operated for the DOE by EG&G.This continuing nationwide program. started in 1958, involves surveys to monitor radiation levels in and around facilities producing, utilizing. or storing radioactive materials. At the request of the DOE, or other federal and/or state agencies (such as the United States Nuclear Regulatory Con, mission), the AMS is deployed for various aerial survey operations.
The AMS was utilized during the period 28-31 March 1977 to radiometrically survey a 2146 km2 area centered on the Edwin 1. Hatch Nuclear Plant located near Baxley, Georgia.
2.0 SITE LOCATION (cps) per u R/ h. An average cosmic ray contribution of The Edwin 1. Hatch Nuclear Plant, operated by the 3.7 pR/h was then added to produce the total Georgia Power Company, is located in Appling CXPosure ratt County, Georgia, near the south bank of the Altamaha Spectral data were accumulated in a 300 channel River, approximately 113 km inland from the Georgia analyzer aboard the aircraft.

Nearby population centers include Baxley, spectrum typical of the natural terrestrial background 18 km to the south, Hazelhurst, 24 km to the near the Hatch Plant is shown in Fig. 6.

chamber located I m above the ground at each sampling position. Sampling was done at the same 3.0 AERIAL MEAS'UREMENTS time the aerial survey was conducted. The soil samples were radiometrically analyzed and tabulated for this The aerial data were accumulated at an altitude of 152 report by a team of scientists at EG&G's Santa m above the terrain along lines 46 km long and spaced Barbara Laboratory. Systems and procedures for soil approximately 0.93 km apart (Fig. 2). Fifty such lines sample data are outlined in a separate publication.*

Fig. 2. Ten soil samples were taken from each of 2 sites Spectral and gross count data were collected (numbers 1 and 6). The results of the soil sample data simultaneously along these lines. Complete systems analysis are presented in Table 1. lon chamber and procedures are described elsewhere.m readings were taken at all 14 sites.

Flights along the Altamaha River were used to 5.0 DISCUSSION determine the non-terrestrial contributions to the observed count rates. Analysis of the radiological data taken over the area surrounding the Edwin 1. Hatch Nuclear Plant ,
The net count rate of terrestrial origin was converted indicated ihat the terrestrial radioisotopes, and to exposure rate (also of terrestrial origin) at I m by associated gamma ray exposure rates, were consistent '

APPENDIX A SITE GEOLOGY The Georgia coastal terraces in the reactor site region The Edwin 1. Hatch Nuclear Plant site is situated in the coastal terrace province of the Georgia coastal plain? are composed of Quaternary and Tertiary sands and This plain is the local expression of a much larger gravels? These marine deposits were derived from the coastal plain encompassing most of the eastern Georgia uplands during higher stands of sea level in seaboard states. The plain was formed on the sea floor the Pleistocene, and deposited on the sea floor. The during higher stands of the sea in the Pleistocene. As lithology of these sands reflects a parentage traceable such, it is a gently seaward sloping, almost featureless, to the crystalline rocks underlying the Piedmont plain. This plain has undergone dissection by streams province of Georgia and neighboring states.
since it was laid bare after the Pleistocene seas The coastal deposits of Georgia represent retreated to their present level. Erosion has only mildly accumulations of land derived sediment formed altered the anpearance of the land surface due to the during interglacial stages of the Pleistocene. These shortness of time this area has been exposed. Several deposits may be correlated with specific shoreline levels of marine terraces are present. These correspond stand which decrease in elevation with decreasing age.

Accordingly it remnants of the uppermost terraces from drainage outcrops further west. Successively younger terrace divides and ridges. Hence, the tops of ridges and deposits outcrop further and further east and at disides are flat or gently undulating, representing the progressively lower elevations. These younger as yet unaltered sea floors as they were laid down. deposits have, therefore, been derived from older, Drainage is fairly well integrated over the entire previously existing marine terraces, and are composed region, though 25% of the land surface is swamp. of material reworked during later interglacial stages.
These swamps generally occur in small shallow upland Due to continued reworking,'errace deposits younger depressions and on river floodplains. Many of the than the Sunderland Formation resemble each other Altamaha tributaries discharge into floodplain closely in lithology.
