Bioenvironmental and radiological-safety feasibility studies, Atlantic-Pacific Interoceanic Canal. Phase 2, Freshwater ecology: Final report

Description: The purpose of this program is to conduct studies in the freshwater environment to acquire data needed to evaluate and predict the potential radiation hazards to human populations in the defined regions of proposed nuclear excavations in the Republics of Panama and Colombia. The results of the field surveys conducted in Phase II are presented in this report. Specifically, the data describes the elemental composition of the major components of the ecosystem, and reports the calculated stable ele… more

TOTAL RADIATION-INDUCED GENETIC DAMAGE IN ENTIRE GENOMES OF DROSOPHILA MELANOGASTER. Technical Progress Report.

Description: Drosophila melanogaster adults are irradiated and then mated to flies containing genetic markers and/or crossover suppressors in all chromosomes. Appropriate genetic schemes are followed to obtain balanced stocks of entire treated genomes. Each chromosome of each genome is observed for visibles, lethals, detrimentals and sterility factors. Tests are made for translocations involving any combination of chromosomes. All chromosomes of each genome are examined cytologically for possible deficienci… more

Device for High Voltage Surge Protection

Description: The memorandum presents a description of an electric furnace used to heal test specimens, and it describes furnace damage caused by electrical arcs when a breaking specimen suddenly opens the inductive circuit. The device, which is applicable to an d-c circuit, provides a gap containing a dielectric material in parallel with he device to be protected. The gap is set to break down at a volatge well below the safe operating voltage of the device to be protected. A high voltage suddenly impressed … more
