Noise pollution is an unwanted or undesirable sound in peripheral environment. In other words, it is indefinite and irregular combination of sounds [ 1 ]. Noise pollution has many effects on humans, including
The plutonium processing facility at Los Alamos has adopted the strategic goal of becoming a facility that processes plutonium in a way that produces only environmentally benign waste streams. Pollution prevention through source reduction and environmentally sound recycling are being pursued. General approaches to waste reductions are administrative controls, modification of process technologies, and additional waste polishing. Recycling of waste materials, such as spent acids and salts, are technical possibilities and are being pursued to accomplish additional waste reduction. Liquid waste stream polishing to remove final traces of plutonium and hazardous chemical constituents is accomplished through (a) process modifications, (b) use of alternative chemicals and sorbents for residue removal, (c) acid recycling, and (d) judicious use of a variety of waste polishing technologies. Technologies that show promise in waste minimization and pollution prevention are identified. Working toward this goal of pollution prevention is a worthwhile endeavor, not only for Los Alamos, but for the Nuclear Complex of the future.
Two programmes of work are described involving the measurement of environmental pollution over periods from two hours to many
years. The long period measurements are deduced from neutron activation analysis of whole wood samples taken from individual
tree rings for trees grown in various locations, and some results for cadmium, antimony and germanium levels are reported.
In a second series of experiments the concentration of airborne particulate matter is being measured using a moving filter
(streak sampler) technique to give a continuous record with two hour resolution. The filter samples are being analysed by
proton induced X-ray emission (PIXE) and preliminary data is presented.
