Ground water originates as precipitation primarily in the Sierra Nevada in the western part of Carson and Eagle Valleys, and flows down gradient in the direction of the Carson River through Dayton and Churchill Valleys to a terminal sink in the Carson Desert. Because radionuclides dissolved in ground water can pose a threat to human health, the distribution and sources of several naturally occurring radionuclides that contribute to gross-alpha and gross-beta activities in the study area were investigated. Generally, alpha and beta activities and U concentration increase from the up-gradient to down-gradient hydrographic areas of the Carson River Basin, whereas<sup>222</sup>Rn concentration decreases. Both<sup>226</sup>Ra and<sup>228</sup>Ra concentrations are similar throughout the study area. Alpha and beta activities and U concentration commonly exceed 100 pCi/l in the Carson Desert at the distal end of the flow system. Radon-222 commonly exceeds 2,000 pCi/l in the western part of Carson and Eagle Valleys adjacent to the Sierra Nevada. Radium-226 and<sup>228</sup>Ra concentrations are &lt;5pCi/l. Four ground water samples were analyzed for<sup>210</sup>Po and one sample contained a high concentration of 21 pCi/l. Seven samples were analyzed for<sup>210</sup>Pb; six contained &lt;3pCi/l and one contained 12 pCi/l. Thorium-230 was detected at concentrations of 0.15 and 0.20 pCi/l in two of four samples.</p><p>Alpha-emitting radionuclides in the ground water originated from the dissolution of U-rich granitic rocks in the Sierra Nevada by CO<sub>2</sub>, oxygenated water. Dissolution of primary minerals, mainly titanite (sphene) in the granitic rocks, releases U to the water. Dissolved U is probably removed from the water by adsorption on Fe- and Mn-oxide coatings on fracture surfaces and fine-grained sediment, by adsorption on organic matter, and by coprecipitation with Fe and Mn oxides. These coated sediments are transported throughout the basin by fluvial processes. Thus, U is transported as dissolved and adsorbed species. A rise in the water table in the Carson Desert because of irrigation has resulted in the oxidation of U-rich organic matter and dissolution of U-bearing coatings on sediments, producing unusually high U concentration in the ground water.</p><p>Alpha activity in the ground water is almost entirely from the decay of U dissolved in the water. Beta activity in ground water samples is primarily from the decay of<sup>40</sup>K dissolved in the water and ingrowth of<sup>238</sup>U progeny in the sample before analysis. Approximately one-half of the measured beta activity may not be present in ground water in the aquifer, but instead is produced in the sample after collection and before analysis. Potassium-40 is primarily from the dissolution of K-containing minerals, probably K-feldspar and biotite. Radon-222 is primarily from the decay of<sup>226</sup>Ra in the aquifer materials. Radium in the ground water is thought to be mainly from alpha recoil associated with the decay of Th in the aquifer material.

Many aquifer systems are characterized by stratification, for example, a sandy layer overlain by a clay layer. To obtain information about separate hydrogeologic units, aquifer pumping tests are often conducted with a well penetrating only one of the layers. When the initial concentration distribution is also stratified (the concentration varies with elevation only), the concentration breakthrough in the pumped well may be interpreted to provide information on aquifer hydraulic and transport properties. To facilitate this interpretation, we present some simple analytical and numerical solutions for limiting cases and illustrate their application to a fractured bedrock/glacial drift aquifer system where the solute of interest is dissolved radon gas. In addition to qualitative information on water source, this method may yield estimates of effective porosity and saturated thickness (or fracture transport aperture) from a single-hole test. Little information about dispersivity is obtained because the measured concentration is not significantly affected by dispersion in the aquifer.","largerWorkTitle":"Proceedings - National Conference on Hydraulic Engineering","conferenceTitle":"Proceedings of the 1993 National Conference on Hydraulic Engineering.

We tested this relationship in California during July and early August 1992, using a portable radonmeter to conduct soil-air radon surveys at 5 sites across three kinds of faults: Creeping, locked, and freshly broken. Along a 350-m long survey line across a creeping segment of the San Andreas fault at Nyland Ranch in San Juan Bautista, we found anomalous radon concentrations not in the creep zone itself as determined by a creepmeter, but on the adjacent sides, 10 and 30 meters from the center line of the fault. The anomalous values were 5 times higher than the background values measured farther away from the fault. A similar radon anomaly was observed along a 420-m long survey line across a creeping segment of the Calaveras fault near 7th Street in Hollister. There, the anomalous values were about 6 to 11 times the background values and about 40 and 50 m from the center line of the fault. The double-peaked featire of the anomalies may be indicative of a relatively low gas permeability of the fault-gouge materials in the creeping zones and high permeability of fractured rocks in the adjacent shear zones. Along a 144-m survey line across the currently locked segment of the San Andreas fault at the Earthquake Trail near Olema, the radon concentration was indeed anomalously high in the fault zone, by a factor of two above background values. However, the maximum values (3 to 6 times background) again were recorded about 10 meters from the center line. Three weeks after the magnitude 7.5 Landers earthquake of 28 June 1992, we conducted a survey along a 300-m line across the earthquake fault alongside Encantado Road in the epicenter area. The radon values measured at the two main fault breaks were an order of magnitude higher than the background values. A similar result was found along a 420-m line alongside Reche Road about 1.7 km south of Encantado Road. ?? 1993 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00876238","issn":"00334553","usgsCitation":"King, C., Zhang, W., and King, B., 1993, Radon anomalies on three kinds of faults in California: Pure and Applied Geophysics PAGEOPH, v. 141, no. 1, p. 111-124, https://doi.org/10.1007/BF00876238.","startPage":"111","endPage":"124","numberOfPages":"14","costCenters":[],"links":[{"id":205834,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00876238"},{"id":227023,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"141","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9434e4b0c8380cd81277","contributors":{"authors":[{"text":"King, C.-Y.","contributorId":81225,"corporation":false,"usgs":true,"family":"King","given":"C.-Y.","affiliations":[],"preferred":false,"id":379348,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhang, W.","contributorId":92399,"corporation":false,"usgs":true,"family":"Zhang","given":"W.","email":"","affiliations":[],"preferred":false,"id":379349,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"King, B.-S.","contributorId":54592,"corporation":false,"usgs":true,"family":"King","given":"B.-S.","email":"","affiliations":[],"preferred":false,"id":379347,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The key variables in the model are bulk properties such as porosity, uranium content of the rock, emanating efficiency, and rock density, all of which are measurable. Thus, the model is simplified by the averaging effects of a macroscopic view of the system. Although less rigorous than other models presented in the literature, it is more generally applicable to natural systems because it does not rely on microscopic properties of the system, which are impossible to quantify.

Some of these sites are located as far as several hundred kilometers away from earthquake epicenters.

They are the soil gas radon concentration and the geological rock type from which soils are derived. A simple soil gas collection and analytical technique has been developed to provide information on soil gas radon concentrations. The application of these techniques has demonstrated a clear relationship between the estimate of the radon potential and indoor radon measurements. This information is particularly important when evaluating the radon potential of areas that will be subject to population expansion in the future. Other factors, such as gamma radiation measurements and soil permeability can be included to improve the estimate of radon potential, but geology and soil gas measurements are the most important factors. Although this approach is useful for regional estimates, it can also be used for site-specific evaluations.","largerWorkTitle":"Radiation Protection Dosimetry","language":"English","issn":"01448420","usgsCitation":"Reimer, G., 1992, Using soil gas radon and geology to estimate regional radon potential, <i>in</i> Radiation Protection Dosimetry, v. 45, no. 1-4 SUPPL., p. 219-221.","startPage":"219","endPage":"221","numberOfPages":"3","costCenters":[],"links":[{"id":223008,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"1-4 SUPPL.","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc0a2e4b08c986b32a233","contributors":{"authors":[{"text":"Reimer, G.M.","contributorId":59800,"corporation":false,"usgs":true,"family":"Reimer","given":"G.M.","affiliations":[],"preferred":false,"id":373213,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Air concentrations determined by alpha-track detectors (ATDs) and continuous radon monitors were compared with the predictions of a single-cell model. In many of the houses, the water supply was shown to contribute significantly to levels of indoor 222Rn. The data from the ATD study were augmented with a continuous monitoring study of a house near Lyons, CO. The well water in that house has the highest known concentration of 222Rn in water yet reported (93 MBq m-3). The temporal pattern in the indoor 222Rn concentration corresponds to water-use records. In general, it is difficult to quantify the proportion of indoor radon attributable to water use. Several lines of evidence suggest that the single-cell model underestimates this proportion. Continuous- monitoring data, although useful, are impractical due to the cost of the equipment. We propose a protocol for 222Rn measurement based on three simultaneous integrating radon detectors that may help estimate the proportion of indoor 222Rn derived from the water supply.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Health Physics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00179078","usgsCitation":"Lawrence, E., Wanty, R., and Nyberg, P., 1992, Contribution of 222Rn in domestic water supplies to 222Rn in indoor air in Colorado homes: Health Physics, v. 62, no. 2, p. 171-177.","startPage":"171","endPage":"177","numberOfPages":"7","costCenters":[],"links":[{"id":225075,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"62","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa80e4b0c8380cd4db28","contributors":{"authors":[{"text":"Lawrence, E.P.","contributorId":65129,"corporation":false,"usgs":true,"family":"Lawrence","given":"E.P.","email":"","affiliations":[],"preferred":false,"id":374329,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wanty, R.

The Reimer technique acquires a small-volume, grab sample of soil gas, whereas the Rogers and Associates technique acquires a large-volume, flow-through sample of soil gas. The two techniques yield similar radon concentrations in well-sorted sands, but do not correlate as well for poorly sorted soils and clays.","largerWorkTitle":"Journal of Radioanalytical and Nuclear Chemistry","language":"English","doi":"10.1007/BF02040479","issn":"02365731","usgsCitation":"Gundersen, L., 1992, The effect of rock type, grain size, sorting, permeability, and moisture on measurements of radon in soil gas: A comparison of two measurement techniques, <i>in</i> Journal of Radioanalytical and Nuclear Chemistry, v. 161, no. 2, p. 325-337, https://doi.org/10.1007/BF02040479.","startPage":"325","endPage":"337","numberOfPages":"13","costCenters":[],"links":[{"id":224570,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205511,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02040479"}],"volume":"161","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bab49e4b08c986b322d40","contributors":{"authors":[{"text":"Gundersen, L.C.S.","contributorId":24501,"corporation":false,"usgs":true,"family":"Gundersen","given":"L.C.S.","email":"","affiliations":[],"preferred":false,"id":375116,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Results of these measurements indicate that some geological units are associated, on the average, with twice as much indoor222Rn as other geological units, and that indoor222Rn varies seasonally. The Kruskal-Wallis test was used to test whether indoor222Rn concentrations for data gathered over the winter and summer seasons differ significantly by rock unit. The tests concluded that indoor222Rn concentrations for different rock units were not equal at the 5-percent significance level. The rocks associated with the highest median indoor222Rn concentration are specific rocks in the Mesozoic Culpeper basin, including shale and siltstone units with Jurassic diabase intrusives, and mica schists in the Piedmont physiographic province. The pre-Triassic Peters Creek Schist has the highest ranking in terms of indoor222Rn concentration. The rocks associated with the lowest indoor222Rn concentrations include coastal plain sediments, the Occoquan Granite, Falls Church Tonalite, Piney Branch Mafic and Ultramafic complex, and unnamed mafic and ultramafic inclusions, respectively. The rocks have been ranked according to observed222Rn concentration by transforming the average rank of indoor222Rn concentrations to z scores. ?? 1992 Springer-Verlag New York Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geology and Water Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01704086","issn":"01775146","usgsCitation":"Brown, C.E., Mose, D., Mushrush, G., and Chrosniak, C., 1992, Statistical analysis of the radon-222 potential of rocks in Virginia, U.S.A.: Environmental Geology and Water Sciences, v. 19, no. 3, p. 193-203, https://doi.org/10.1007/BF01704086.","startPage":"193","endPage":"203","numberOfPages":"11","costCenters":[],"links":[{"id":205600,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01704086"},{"id":225104,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9715e4b08c986b31b887","contributors":{"authors":[{"text":"Brown, C.
