Western United States. Although the milling process yields a uranium concentrate, the large volume of tailings remaining contains about 85 percent of the radioactivity originally associated with the ore. By virtue of the physical and chemical processing of the ore and the redistribution of the contained radionuclides at the Earth's surface, these tailings constitute a technologically enhanced source of natural radiation exposure. Sources of potential human radiation exposure from uranium mill tailings include the emanation of radon gas, the transport of particles by wind and water, and the transport of soluble radionuclides, seeping from disposal areas, by ground water. Due to the 77,000 year half-life of thorium-230, the parent of radium-226, the environmental effects associated with radionuclides contained in these railings must be conceived of within the framework of geologic processes operating over geologic time. The magnitude of erosion of cover materials and tailings and the extent of geochemical mobilization of the contained radionuclides to the atmosphere and hydrosphere should be considered in the evaluation of the potential, long-term consequences of all proposed uranium mill tailings management plans.","language":"ENGLISH","publisher":"Dept. of the Interior, Geological Survey,","doi":"10.3133/cir814","usgsCitation":"Landa, E., 1980, Isolation of uranium mill tailings and their component radionuclides from the biosphere; some earth science perspectives: U.S. Geological Survey Circular 814, iii, 32 p. :ill., map ;26 cm., https://doi.org/10.3133/cir814.","productDescription":"iii, 32 p. :ill., map ;26 cm.","costCenters":[],"links":[{"id":124670,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1980/0814/report-thumb.jpg"},{"id":30808,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1980/0814/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9fe4b07f02db660e2e","contributors":{"authors":[{"text":"Landa, Edward","contributorId":100368,"corporation":false,"usgs":true,"family":"Landa","given":"Edward","affiliations":[],"preferred":false,"id":147523,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This paper proposes a model that may explain the observed tectonic variations in radon emanation, and explores the possibility of using radon emanation as an indicator of crustal deformation. In this model the emanation variation is assumed to be due to the perturbation of near-surface profile of radon concentration in the soil gas caused by a change in the vertical flow rate of the soil gas which, in turn, is caused by the crustal deformation. It is shown that, for a typical soil, a small change in the flow rate (3 · 10</span><sup>−4</sup><span>&nbsp;cm sec</span><sup>−1</sup><span>) can effect a significant change (a factor of 2) in radon emanation detected at a fixed shallow depth (0.7 m).

Radium ranges from 0.3 to 420 picocuries per liter and has a median value of 8.8, and uranium ranges from 0.02 to 180 micrograms per liter and has a median value of 2.4. Radon concentrations, measured in 32 of the 37 wells, range from less than 100 picocuries per liter to as much as 27,000 and have a median value of 580. Relationships among the radioactive elements and 28 other geochemical parameters were studied by using correlation coefficients and R-mode factor analysis. Five factor groups were determined to represent major influences on water chemistry: (1) short-term solution reactions, (2) oxidation reactions, (3) hydrolysis reactions, (4) uranium distribution, and (5) long-term solution reactions. Uranium concentrations are most strongly influenced by oxidation reactions but also are affected by solution reactions and distribution of uranium in the rocks of the aquifer system. Radon and radium concentrations are mostly controlled by uranium distribution; radium also shows a moderate negative relationship with oxidation. \r\n\r\nTo explain the statistical and spatial relationships among the parameters, a model was developed involving the selective leaching of uranium-bearing phases and metal sulfides which occur in discontinuous zones in sandstone and shale. When reducing conditions prevail, uranium is immobile, but radium can be taken into solution. When faults and associated fractured rocks allow oxidizing conditions to dominate, uranium can be taken into solution; radium can also be taken into solution, or it may become immobilized by coprecipitation with iron and manganese oxides or with barite. Several areas within the study area are discussed in terms of the model.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79974","usgsCitation":"Felmlee, J., and Cadigan, R.A., 1979, Radium and uranium concentrations and associated hydrogeochemistry in ground water in southwestern Pueblo County, Colorado: U.S. Geological Survey Open-File Report 79-974, iv, 54 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr79974.","productDescription":"iv, 54 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":142734,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0974/report-thumb.jpg"},{"id":36378,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0974/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db649aaa","contributors":{"authors":[{"text":"Felmlee, J.

The discharge contains high concentrations of radon, and the gross alpha activity and the concentration of adium-226 exceed maximum levels recommended by the Environmental Protection Agency for drinking water. Part of the discharge is diverted for space heating, bathing, and domestic use. The radioactive thermal waters at measured temperatures of about 60&deg;C are  of the sodium bicarbonate type and saturated with respect to calcium carbonate. Radium-226 in the rock and on fractured surfaces or coprecipitated with calcium carbonate probably is the principal source of radon that is dissolved in the thermal water and discharged with other gases from some wells and springs. Local surface water and shallow ground water are of the calcium bicarbonate type and exhibit low background activity. The temperature, percent sodium, and radioactivity of mixed waters adjacent to the fault zone increase with depth. Samples from most of the major hot springs in southwestern Montana have been analyzed for gross alpha and beta activity. The high level of radioactivity at Alhambra appears to be related to leaching of radioactive material from siliceous veins by ascending thermal waters and is not a normal characteristic of hot springs issuing from fractured crystalline rock in Montana.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Leonard, R., and Janzer, V.J., 1978, Natural radioactivity in geothermal waters, Alhambra Hot Springs and nearby areas, Jefferson County, Montana: Journal of Research of the U.S. Geological Survey, v. 6, no. 4, p. 529-540.","productDescription":"12 p.","startPage":"529","endPage":"540","costCenters":[{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"links":[{"id":266911,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266910,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1978/vol6issue4/report.pdf","text":"Report","size":"18.0 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Montana","county":"Jefferson County","otherGeospatial":"Alhambra Hot Springs","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -112.5948,45.7485 ], [ -112.5948,46.5725 ], [ -111.6586,46.5725 ], [ -111.6586,45.7485 ], [ -112.5948,45.7485 ] ] ] } } ] }","volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"510e4381e4b09f303997b292","contributors":{"authors":[{"text":"Leonard, Robert B.","contributorId":14407,"corporation":false,"usgs":true,"family":"Leonard","given":"Robert B.","affiliations":[],"preferred":false,"id":472908,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Janzer, Victor J.","contributorId":36119,"corporation":false,"usgs":true,"family":"Janzer","given":"Victor","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":472909,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

When, used as total-count devices, the sondes are comparable in logging speed and counting rate with conventional scintillation detectors for locating zones of high radioactivity. When used with a multichannel analyzer, the sondes are detectors with such high resolution that individual lines from the complex spectra of the uranium and thorium series can be distinguished. Gamma rays from each group of the uranium series can be measured in ore zones permitting determination of the state of equilibrium at each measurement point. Series of 10-minute spectra taken at 0.3- to 0.5-m intervals in several holes showed zones where maxima from the uranium group and from the 222Rn group were displaced relative to each other. Apparent excesses of 230Th at some locations suggest that uranium-group concentrations at those locations were severalfold greater some tens of kiloyears, ago. At the current state of development a 10-minute count yields a sensitivity of about 80 ppm U308. Data reduction could in practice be accomplished in about 5 minutes. The result is practically unaffected by disequilibrium or radon contamination. In comparison with core assay, high-resolution spectrometry samples a larger volume; avoids problems due to incomplete core recovery, loss of friable material to drilling fluids, and errors in depth and marking; and permits use of less expensive drilling methods. Because gamma rays from the radionuclides are accumulated simultaneously, it also avoids the problems inherent in trying to correlate logs made in separate runs with different equipment.\r\n\r\nContinuous-motion delayed-gamma activation by a 163-?g 252Cf neutron source attached to the sonde yielded poor sensitivity. A better neutron-activation method, in which the sonde is moved in steps so as to place the detector at the previous activation point, could not be evaluated because of equipment failure.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77571","usgsCitation":"Tanner, A.B., Moxham, R.M., and Senftle, F.E., 1977, Assay for uranium and determination of disequilibrium by means of in situ high resolution gamma-ray spectrometry: U.S. Geological Survey Open-File Report 77-571, 22, 11 leaves :ill.

The rocks in Canada contain major deposits of uranium in quartz-pebble conglomerates near the base of the metasedimentary sequence. Similar conglomerates in the Deep Lake Formation in the Medicine Bow Mountains of southeastern Wyoming are slightly radioactive and may contain deposits of uranium and other valuable heavy metals. \r\n\r\nDuring the summer of 1976, a geological and geochemical pilot study was conducted in the vicinity of Arrastre Lake in the Medicine Bow Mountains to determine the most effective exploration methods for evaluating the uranium potential of the Snowy Range wilderness study area. The area around Arrastre Lake was selected because of the presence of a radioactive lens within a quartz-pebble conglomerate of the Deep Lake Formation. The results of the survey indicate possible uranium mineralization in the subsurface rocks of this formation. \r\n\r\nThe radon content of the dilute waters of the area is much higher than can be accounted for by the uranium content of the surface rocks. Two sources for the high content of the radon are possible. In either case, the high values of radon obtained in this study are a positive indication of uranium mineralization in the subsurface rocks. \r\n\r\nThe determination of the radon content of water samples is the recommended geochemical technique for uranium exploration in the area.

Radon and its daughter products principally cause the discrepancies. Experimental work was undertaken by the writers to learn the relations of the radon to the uranium deposits and its behavior under different physical conditions. The work is based on the interpretation of about 600 gamma-ray logs, taken from 480 drill holes.Abnormally high amounts of radon, referred to here as contamination, ranged from barely detectable amounts to amounts that emitted as much radiation as ore-grade material. Most contaminated holes were in the higher-grade ore, and the contamination increased with elapsed time after drilling. Geologic conditions favorable for contamination by radon and its daughter products in drill holes are: proximity to uranium deposits and fractured or highly permeable rocks above the water table. Most drill holes can be decontaminated by blowing them out with compressed air or filling them with water. Water, however, tends to reduce the thickness-times-grade figures below the amounts determined in air.</span></p>","language":"English","publisher":"Society of Economic Geologist","doi":"10.2113/gsecongeo.52.4.438","usgsCitation":"Hilpert, L.S., and Bunker, C.M., 1957, Effects of radon in drill holes on gamma-ray logs: Economic Geology, v. 52, no. 4, p. 438-455, https://doi.org/10.2113/gsecongeo.52.4.438.","productDescription":"18 p.","startPage":"438","endPage":"455","costCenters":[],"links":[{"id":380481,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New Mexico","otherGeospatial":"Near Grants","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.7923583984375,\n              35.160336728130346\n            ],\n            [\n              -107.38037109375,\n              35.160336728130346\n            ],\n            [\n              -107.38037109375,\n              35.43381992014202\n            ],\n            [\n              -107.7923583984375,\n              35.43381992014202\n            ],\n            [\n              -107.7923583984375,\n              35.160336728130346\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"52","issue":"4","noUsgsAuthors":false,"publicationDate":"1957-06-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Hilpert, Lowell Sinclair","contributorId":117367,"corporation":false,"usgs":true,"family":"Hilpert","given":"Lowell","email":"","middleInitial":"Sinclair","affiliations":[],"preferred":false,"id":804781,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bunker, Carl Maurice","contributorId":77526,"corporation":false,"usgs":true,"family":"Bunker","given":"Carl","email":"","middleInitial":"Maurice","affiliations":[],"preferred":false,"id":804782,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
