Soleado Elementary School

The data collected at Soleado Elementary School are presented here. Figure 1 is a schematic of the school site that shows the rooms that were tested for indoor radon colored according to the amount of radon in the rooms. Figure 1 also show the approximate locations of the sites where field gamma-ray measurements were made. Table 1 lists the results of the field gamma-ray measurements. Samples of the top five inches of soil were collected and two of the gamma-ray sites and Table 2 lists the results of analyses of those samples. Table 3 lists the results of the indoor radon measurements.

Table 1. Results of gamma-ray spectrometer measurements at Soleado Elementary School. Site locations are indicated in Figure 1 (e.g. location number 1 refers to SEP1). The column labeled "Group" identifies the group to which the measurement was assigned as a result of classification of the gamma-ray data.

Table 2. Results of laboratory measurements of soil samples. The K, eU, and eTh concentrations were determined by a laboratory gamma-ray spectrometer and the field results are presented for comparison. Radon emanation fraction was determined as discussed in the section on methodologies.
