Survey) YVONNE North End : No. of Samples 1 Profile 1 Profile h6 Profiles (120-180 cm) In addition to those samples collected objectively from hot spots, etc., where elevated concentrations were expected or observed, special _semples were collected at each site where thermoluminescent dosimeters (TLD) were placed for exposure rate determination. (The TLD program will be dis- cussed with the terrestrial radiation survey effort further in the text.) At each of these sites, two sets of surface samples were collected. 5 first set included double core samples from the surface to 5 cm depth. The second set included cores from the surface to 15 cm depth. Each set was made up from a composite taken from the area directly under the TLD and from a location about 10-15 feet from the TLD at each cardinal point. Thus, for the shallow set, two cores each were taken from five separate locations and composited into a single shallow sample (i.e., 10 cores). For the deep set, single cores were taken from the same five locations and composited into a single deep sample (5 cores). . These samples would be analyzed to provide representative soil data around each TLD location to assist in evaluating the soil contribution to the terrestrial radiation exposure rate. The objective sampling locations for the TLD study are indicated in Table 6. There were approximately 860 collections made, composited into 172 separate samples in support of the TLD effort. v9
