soil of minimum organic content could have concentrated more *37Gs in its immediate vicinity. The TLD results at the other locations along this transect are in excellent agreement with the other data. Total and Individual Isotope Exposure Rates Along the Village Road Transect - Twenty-one hundred feet of the Village Road between 0 and 1 Transects (see Figv~e 3) were surveyed. Scintillation and Geiger counter readings were made every 150 ft. as determined with a marked 150 ft. length of rope. These Measurement points coincided with the placement of NRDL TLD dosimeter packages. Spectrometer and ionization chamber measurements were made at the beginning of the transect, Location 4, and at the midpoint, Location 9. The road was generally clear of brush, particularly past the 1200 ft. point toward the Tent 2 area. The soil was rather sandy and weathered, and the radiation levels were relatively low and uniform, from 20 to 40 ur/hr from 0 ft. to 1040 ft., and from 8 to 18 pr/hr from 1350 ft. to 2100 ft. Only the 1200 ft. point was located in the midst of somewhat denser vegetation. The exposure rate measurements at this location were correspondingly higher; about 57 ur/hr. The Spectrometer and ion chamber measurements are summarized below. SPECTROMETER AND IONIZATION CHAMBER EXPOSURE RATES (ur/br) Location 137 O5 6° Co 125 Sb Total As 4 Q' 17.7 (80%) 1.7 (8%) 2.8 (13%) 22.2 24.6 9 26.7 (77%) 3.9 (11%) 4.0 (12%) 34.6 37.5 1050' The dominant emitter again is **°’Cs, contributing 77 to 80% of the total exposure rate. No soil samples were taken. The TLD results (Table 1) also show the same pattern as the portable meter readings, although the HASL results at Locations 4 and 9 are quite high, possibly for the same reasons as discussed in reference to the Location 2 result. e OAL OS “4s anh poe:
