Surface and subsurface cleanup protocol for radionuclides, Gunnison, Colorado, UMTRA project processing site. Final report: Revision 1

Description: Surface and subsurface soil cleanup protocols for the Gunnison, Colorado, processing site are summarized as follows: In accordance with EPA-promulgated land cleanup standards, in situ Ra-226 is to be cleaned up based on bulk concentrations not exceeding 5 and 15 pCi/g in 15-cm surface and subsurface depth increments, averaged over 100m{sup 2} grid blocks, where the parent Ra-226 concentrations are greater than, or in secular equilibrium with, the Th-230 parent. In locations where Th-230 has dif… more

A Study in Human Resources Utilization: A Critical Examination of the Role of the Self-Concept in the Vocational Choice Process of College Students

Description: The specific problem confronted by this dissertation research is this: Do college students who are quite decided about their vocational choices have more developed and implemented self-concepts than do college students who are quite undecided about their vocational choices? If the decided students have more developed and implemented self-concepts than the undecided students, it can be logically reasoned that the developing and implementing of the self-concept is essential in the vocational choi… more

Thorium and Rare-Earth Minerals in Powderhorn District, Gunnison County, Colorado

Description: From abstract: Thorium has been found since 1949 in at least 33 deposits in an area 6 miles wide and 20 miles long in the Powderhorn district, Gunnison County, Colo. The district is underlain largely by pre-Jurassic metamorphic and igneous rocks, most of which, if not all, are pre-Cambrian in age. These rocks are overlain by sandstone of the Morrison formation of Jurassic age, and by volcanic rocks of the Alboroto group and the Hinsdale formation of Miocene and of Pliocene(?) age, respectively.

Thorium and rare earth minerals in the Powderhorn district, Gunnison County, Colorado

Description: "Thorium deposits were discovered in the Powderhorn district in 1949. This district has long been known for its occurrences of alkalic igneous rocks, of which the best known is the Iron Hill complex (Larsen, 1942). Some of these alkalic rocks contain titanium, barium, strontium, rare earths, thorium, and niobium in greater percentages than those of most igneous rocks. A study of the thorium deposits was undertaken to obtain more information on the geologic relation of minor elements, particular… more
