556. lappuse - I am pleased to be here today to discuss the results of our review of the Navy's mine countermeasures capabilities and plans.
374. lappuse - As a result, the radioactivity concentration guide for carbon 14 in its chemical form in air issued by the International Commission on Radiological Protection, the National Council on Radiation Protection and Measurements, the US Nuclear Regulatory Commission and by other standard-setting organizations is three thousand times higher than for cobalt 60.
112. lappuse - LSD 41 (Cargo variant). This ship will transport and launch amphibious craft and vehicles with their crews and embarked personnel in amphibious assault operations. It will also provide limited docking and repair services for conventional landing craft and LCAC. The ship will differ from the original LSD 41 in that it will have additional cargo capacity and two fewer LCAC.
317. lappuse - TLD's and TLD readers in use at program activities. Precision TLD's are pre-exposed to exact amounts of radiation by the National Institute of Standards and Technology, formerly the National Bureau of Standards, and provided to program activities for reading.
366. lappuse - The radioactivity in materials discussed in this report originates in the pressurized water reactors of US Naval nuclear-powered ships. As of the end of 1988, the US Navy had 134 nuclear-powered submarines and fourteen nuclear-powered surface ships in operation.
377. lappuse - RADIOACTIVE WASTE DISPOSAL During maintenance and overhaul operations, solid lowlevel radioactive wastes consisting of contaminated rags, plastic bags, paper, filters, ion exchange resin and scrap materials are collected by nuclear-powered ships and their support facilities. These low level radioactive materials from nuclear-powered ships are required to be strictly controlled to prevent loss.
400. lappuse - Naval nuclear-powered ships and support facilities have not caused a measurable increase in the general background radioactivity of the environment. 4. Low-level cobalt 60 radioactivity in harbor bottom sediment is detectable around a few...
836. lappuse - Defense, the Secretary of the Navy, the Chief of Naval Operations and the Commandant of the Marine Corps, we have a multitude of initiatives well underway to make our infrastructure more effective and less costly.
372. lappuse - However, trace quantities of naturally occurring uranium impurities in reactor structural materials release small amounts of fission products to reactor coolant. The concentrations of fission products and the volumes of reactor coolant released are so low, however, that the total radioactivity attributed to long-lived fission product radionuclides, strontium 90 and cesium 137, in releases from US Naval nuclear-powered ships and their support facilities has been less than 0.001 curie per year for...
363. lappuse - Director Naval Nuclear Propulsion ABSTRACT The environmental effect of disposal of radioactive wastes originating from US Naval nuclear propulsion plants and their support facilities is assessed. The total...
