Abstract: Two nuclear accidents involving a plutonium sphere just subcritical in size occurred at the Los Alamos Laboratory, LA-1 in 1945 and LA-2 in 1946. Because remote control devices were deemed unreliable at the time, the tamper material (tungsten carbide bricks in LA-1 and beryllium hemispheres in LA-2) was added by hand with the operator standing next to the assembly. In each case the critical size of the assembly was accidentally exceeded and the resultant exponentially increasing chain reaction emitted a burst of neutrons and gamma rays. Ten persons were exposed to the radiation bursts which were largely composed of neutrons. The doses ranged from fatal in the case of the two operators, to small in the case of some survivors. The two operators died within weeks as a result of acute radiation injury. Only six of the eight survivors were available for follow-up study ten or more years after the accident. Four of these six survivors are now dead, but the two living survivors are in excellent health with no clinical or laboratory evidence of late radiation injury. Two of the deceased died of acute myelogenous leukemia, another died at age 83 of refractory anemia, and the fourth of …

From introduction: This volume contains information and survey results pertaining specifically to the Saint Johns NTMS 1:250,000 scale Quadrangle, Arizona and New Mexico, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

This report contains aerial radiometric and magnetic survey data for Tularosa National Topographic Map of New Mexico.

Preface: This report contains data and information on the resurvey effort and the effect of residual contamination as a result of nuclear weapons development programs conducted in this area.

From preface: The report which follows is the second phase of a DOE contract designed to address various aspects of the genesis of the uranium deposits of the Grants mineral.belt. Many of the problems outlined in Phase 1 of this study (Brookins, 1976a) have been answered, others have been raised.

From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

Report of reconnaissance of the Albuquerque NTMS quadrangle through water and sediment samples collected from springs, wells, and streams. Samples analyzed for uranium and 42 other elements. This report is limited to samples containing uranium concentrations greater than the arbitrary anomaly thresholds of 5 parts per billion for waters and 6 parts per million for sediments.
