Analysis of potential radiation-induced genetic and somatic effects to man from milling of uranium

Description: Potential mortality from natural causes and from radiation exposure conditions typical of those in the vicinity of uranium mills in the western USA was calculated. The exposure conditions were those assumed to exist in the vicinity of a hypothetical model mill. Dose rates to organs at risk were calculated as a function of time using the Uranium Dispersion and Dosimetry Code (Momeni et al. 1979). The changes in population size, birth rates, and radiation-induced and natural mortalities were calc… more

Crystal Field Interaction and Magnetic Order in GdBa/sub 2/Cu/sub 3/O/sub 7/

Description: We report experimental data on the crystal field interaction of Gd ions with their environment in Gd/sub x/Eu/1-x/Ba/sub 2/Cu/sub 3/O/sub 7/. The ESR spectrum and a Schotiky anomaly in the specific heat of dilute samples indicate the existence of a crystal field splitting of the /sup 8/S/sub 7/2/ ground state of the Gd/sup 3 +/ ions of about 1.5K. Since the single ion energies involved are of the same order of magnitude as the energies associated with the magnetic ordering of the Gd moments in … more

Resistivity of EuBa/sub 2/(Cu/sub 1-y/Zn/sub y/)/sub 3/O/sub x/ as a function of temperature, magnetic field, pressure and Zn concentration

Description: We report electrical resistance and magnetoresistance measurements on EuBa/sub 2/(Cu/sub 1-y/Zn/sub y/)/sub 3/O/sub x/ under pressure to 17 kbar. With Zn substitution, T/sub c/ is depressed rapidly (approx.19 K/at.% Zn) and there are qualitative changes in the temperature and field response of the resistance. Pressure drives the Zn-substituted samples toward undoped EuBa/sub 2/Cu/sub 3/O/sub x/ behavior. Analysis of the temperature dependent resistance for y = 0.05 and P = O, together with Hall… more
