  • However, rather than investments in local health infrastructure, funds were used to periodically transport medical staff and supplies from the United States to the Marshall Islands for brief examinations of the "exposed" and "control" populations; to analyze the samples that were collected; to occasionally treat conditions that were defined as radiogenic in nature; and, in later years, to acquire and supply a ship with the necessary technology to conduct whole-body counting, x-ray, and other laboratory procedures.


  • “The radiogenic particles flooding out of it could be collected, I suppose . . . used for fuel?”

  • Today's oceans and continents are thus transitory features produced by incessant geotectonic processes that are energized by three sources of the earth's heat: energy conducted through the lithosphere from the underlying hot mantle, radiogenic decay of heat-producing crustal elements, and convective transport by magmas and fluids during orogenic events.

  • The authors “present a varve thickness chronology from glacier-dammed Iceberg Lake 60°46'N, 142°57'W in the southern Alaska icefields,” where “radiogenic evidence confirms that laminations are annual and record continuous sediment deposition from AD 442 to AD 1998,” and where “varve thickness increases in warm summers because of higher melt, runoff, and sediment transport.”
