Introduction to albedo neutron dosimeters
The design, operation, calibration, and performance of albedo neutron dosimeters are discussed. An albedo neutron dosimeter is designed to measure the flux of thermal neutrons which leave the body when a person is exposed to fast energy neutrons. The fast neutrons are scattered and moderated in the body, and many have lost most of their initial energy and emerge as thermal neutrons. The albedo neutron dosimeter is designed to detect this flux of thermal neutrons by using a thermal neutron detector. This could be any type of thermal neutron detector but in practical applications lithium fluoride (LiF) thermoluminescence dosimeters (TLDs) are most frequently used. Various types of albedo neutron dosimeters are described. (WHK)

Universal formula for the quasistatic second-order density perturbation by a cold magnetoplasma wave
Using the general expression for the ponderomotive Hamiltonian, the quasi-static quasi-neutral density change caused by the ponderomotive force of a cold magnetoplasma wave of arbitrary frequency and polarization is obtained. This formula agrees with and extends previous results for unmagnetized and magnetized plasma.

Comments on muon trapping. [HALO computer code]
Muons that result from the collisions of protons in the ISABELLE beams with other nucleons introduce important background or signal for experiments. Their ability to pass through the conductors and steel of ISABELLE magnets results in complicated trajectories. Some oscillate about quasistable orbits and are called ''trapped.'' A number of typical trajectories were plotted, and flux estimates were made with a Monte Carlo program, HALO. Trapping tends to reduce shielding requirements somewhat, but the effect does not appear to be a very large one from these initial investigations. More aspects need to be studied, and HALO appears to be a useful tool for doing so.

Hydrogenation of CO and CO/sub 2/ on clean rhodium and iron foils. Correlations of reactivities and surface compositions
An experimental arrangement consisting of an ultrahigh vacuum bell jar equipped with an internal sample isolation cell was used to investigate the hydrogenation of CO over Fe and Rh surfaces. This apparatus permitted both UHV surface characterization (Auger electron spectroscopy, low-energy electron diffraction) and high pressure (1-20 atm) catalytic reactions to be carried out. Small surface area (approximately 1 cm/sup 2/) metal samples, both single crystals and polycrystalline foils, were used to catalyze the H/sub 2//CO reaction at high pressures (1-6 atm). Reaction products were monitored with a gas chromatograph equipped with a flame ionization detector. The surface compositions of the metal samples were determined before and after the reaction and the results correlated with the observed product distributions and reaction rates. In addition, the influence of various surface additives (carbon, oxygen, potassium) was also investigated. Iron was the more reactive of the two metals studied and was found to produce C/sub 1/-C/sub 5/ straight chain hydrocarbons but it poisoned rapidly. The catalytically active surface of both metals was covered with a carbonaceous monolayer. The carbonaceous monolayer was stable on the rhodium surface and produced C/sub 1/-C/sub 4/ hydrocarbons at a steady rate even after several hours of reaction. The …

Ordered S-matrix approach to the topological expansion for baryons and mesons. [Ordered Hilbert space, Reggeon closed loops]
A proposal is made for extending to processes involving baryons the ordered Hilbert space approach to the topological expansion. The proposal is based on a topological classification scheme for baryonic processes that is similar to one used previously for the lowest-order contributions, but is in terms of the minimum number of reggeon closed loops instead of handles.

Secondary recovery of plutonium and americium from process waste streams by solvent extraction
A solvent extraction process is being evaluated for the secondary recovery of plutonium and americium from Rocky Flats waste streams. The bidentate organophosphorus compounds dihexyl-N,N-diethylcarbamylmethylene phosphonate and its dibutyl analogue have been shown to be selective extractants for the actinides from solutions of nitric acid. The results from laboratory test runs in which the organophosphorus extractants were used for processing secondary waste solutions will be presented. Solvent extractant properties and purification procedures are discussed.

Inverse problems in remote sensing. Progress report
Research was conducted to improve on presently used techniques for mapping soundspeed variations in the earth by monitoring the return from seismic probes. For small variations in the propagation speed, a linear integral equation was derived for that soundspeed variation. The integral equation is sufficiently general to characterize the placement of sources and receivers. The integral equation was solved in closed form for most of the source-receiver configurations of practical interest. The problem of dealing with the imperfect and incomplete data obtained in the real world was also confronted. The realistically constrained solution was implemented on the computer for a source-receiver configuration commonly used in seismic profiling. This latter project has dominated much of the research effort over the recent contract period.

Risk assessment and radioactive waste management
Problems associated with radioactive waste management, both technological and administrative, have become a serious constraint in the development of nuclear power. An approach toward understanding these problems consists of placing them in a perspective where the risks of radioactive waste management might be evaluated in relation to similar problems facing society so that consistent judgments can be made.

The truck driver, J. C. Kunkle, 47, of 7824 NW 7, told police he lost control of the vehicle when he swerved to avoid another car. The truck struck a traffic signal and concrete median before rolling onto the car which was stopped for a red light. Officers said the woman was taken to University Hospital with minor injuries."
