The National Science Foundation's Support of Research on Uses of Ionizing Radiation in Treatment of Water and Wastes

Astronomical Science from a Lunar Base

The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...

Design and Construction of a Lunar Outpost Assembly Facility

Occupational and Environmental Exposures to Radon: A Perspective for Mitigators
Occupational exposures to radon and radon decay products and the associated high incidence of radiation induced lung cancer form the basis for our present-day concern for limiting exposures...

The Effect of UV Radiation on THM Formation in Drinking Waters
This study was undertaken to investigate the feasibility of using combined UV radiation/chlorination process in drinking water treatment for disinfection while producing lower concentrations...

Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...

A Comparison of Reclamation Plans at Title I and Title II Uranium Mill Tailings Sites

Radiation Hazards to Space Construction - The Energetic Particle Environments
Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...

Containerless Coating Processes for Large Space Structures
Large space structures (LSS) in low earth orbit (LEO) must be able to withstand the deleterious effects of in situ ultraviolet radiation, atomic oxygen, and thermal-cycling-induced microcracking....

Thermal Effects on Large Space Structures with Fixed Attitude
Radiation thermal effects are studied simultaneously on the orbital motion and axial deformation of a very large axially flexible space structure executing planar pitch motion around the...

Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...

Non-Ionizing Radiation Exposure in Space Activities
Non-ionizing radiation exposure has received considerable attention over the past few years due to the potential health hazards involved. Different limits have been set with no international...

A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...

Sintering Lunar Simulants Using 2.45 GHz Radiation
In situ sintering of lunar regolith may be useful for slope stabilization, dust control, and other applications around a lunar base. Having a knowledge of the mechanical properties of...

The Ultrasonic Ranging and Data System for Radiological Surveys in the UMTRA Project

Thermodynamic Factors in Evapotranspiration
Many of the methods discussed in this paper are refinements of procedures presented in the report 'Consumptive Use of Water and Irrigation Water Requirements'...

Dormant Season Evapotranspiration in Alfalfa
Weekly values of maximum temperature, minimum temperature, and solar radiation were examined for their effect upon weekly dormant season evapotranspiration (ETdorm) in perennial alfalfa....

CWSI and Stomatal Resistance of Cotton and Soybeans
A new instrument, Scheduler(TRADEMARK), has been developed to measure the onset and duration of plant water stress. This device consists of a sensor package (containing an infrared thermometer,...
