- Description
- Gamma Detection Equipment General Background: Historic nuclear testing at the Nevada Test Site (NTS) produced radionuclide contamination of the surface and near-surface soils. The Environmental Restoration Soils Project of the U.S. Department of Energy (DOE), National Nuclear Safety Administration/Nevada Site Office (NNSA/NSO) has the mission to characterize sites of near-surface soil contamination. One component of the characterization of soils sites is the performance of GPS-assisted gamma walkover surveys to map the relative contaminant concentrations and distributions. The size of a site can vary from a low of several hundred square-meters to an area in excess of 10 million square-meters. The large area involved, in some sites, necessitates a shift towards a vehicle-born system to improve efficiency and to allow larger areas to be investigated. Working Environment: Topography: The NTS lies on the transition between the Mojave and Great Basin Deserts. The areas to be surveyed vary from dry lake beds to high volcanic plateaus. In some areas, erosion of the surrounding mountains has resulted in the accumulation of more than 1,000 feet of coarse alluvial and unconsolidated gravel deposits. The requested survey equipment will be used in areas dense in vegetation of varying types and concentrations, including grasses, sagebrush and creosote. Joshua trees and Yucca are present but will be avoided during the surveys. Weather: During the summer months, the climate is arid with limited precipitation, low humidity, large daily temperature ranges, and intense solar radiation. The highest maximum temperature measured on the NTS is 115oF and the coldest minimum temperature measured -14oF. Altitude: 2,700 feet to 7,680 feet above mean sea level. Radiation Levels: Near the historic ground zeros of above-ground nuclear tests, typical radiation levels can vary from a background of 10 micro-roentgens per hour to levels of 250 micro-roentgens per hour. Surveys in such high levels are not generally necessary. The typical working environment is 10 to 60 micro-roentgens per hour. Contaminants of Concern: After many years of radioactive decay, the remaining predominant radionuclides to be investigated utilizing the proposed survey equipment: • Cs-137 • Eu-154 Plutonium contamination (with the attendant Am-241 contaminant) may be present at some sites, but will be investigated with other survey equipment. Required Capabilities: Physical: A complete, "turn-key" system is required, with the exception of a four wheel-drive vehicle, which will be provided by the system user. The system shall be mounted on a wheeled or tracked trailer that can be towed, using a standard ball hitch. The trailer and radiation detector array shall have adequate clearance and/or design features to pass over or through typical sagebrush and creosote bushes. The combination of tires, or tracks trailer clearance, and trailer suspension should be able to accommodate undulating terrain, large gravel, and the ephemeral streams which are common to the NTS. If tires are used, they should be easily removed and replaced under field conditions and must be able to accommodate the desert environment. A spare tire shall be provided with the trailer. Maintaining a very short wheel base between the front of the towing vehicle and the rear of the trailer shall be emphasized. For planning purposes, the design can assume that a Polaris Ranger four-wheel drive vehicle will be utilized, although the design should accommodate a wide array of vehicle possibilities. The system shall, to the greatest extent practicable, be contained on the trailer. Power may be obtained from the vehicle. The display of survey route and track information shall be designed for temporary mounting in the vehicle cab. If electronics are required to be carried in the vehicle, the components shall be designed to be portable, rugged, self-contained, with a minimum of components and connectors. Radiation detectors must be rugged and reliable. Detectors shall be mounted approximately 12 to 16 inches above the working ground surface, although a larger distance may be proposed if detection capabilities are not severely compromised. The detector array should cover a width of approximately 36 to 48 inches in a single pass (i.e., approximately the width of the towing vehicle). Detectors shall be enclosed in a weather-resistant housing that is capable of withstanding routine contact with vegetation. Radiation detectors must be able to tolerate prolonged exposure to direct desert sunlight and heat while contained within protective enclosures. If computer equipment is required for the stand-alone system, Dell is the established standard with Windows XP; wireless, camera and microphone are not permitted. Radiological: The system shall be capable of collecting detector array gross count-rate and geophysical position information data. Isotopic discrimination and/or the setting of photon energy windows are not needed. The radiation detection system design shall focus on the detection of Cs-137 and Eu-154 contamination in soil. The system design goal is an adequate sensitivity to be able to reliably detect a 1m2 spot of Cs-137 surface soil contamination at approximately 50 pico-curies per gram. Performance testing and certification is not required. Other design sensitivities may be proposed. GPS: The system shall collect geophysical position information via GPS with 1 meter accuracy or better. The position data shall be capable of differential correction. The GPS system shall be an integral part of the overall radiation detection system. GPS equipment may be mounted on the trailer and display may be routed to the vehicle cab. Automatic data-logging of the position information and output of the radiation detector array shall occur at 1 second intervals. Data storage shall be capable of reliably logging at least 4 continuous hours of information. The ability to easily start and stop data logging from the vehicle cab is highly desirable. GIS: GPS and radiation detector data must be compatible with ESRI ArcGIS 9 Geographical Information System (GIS) products. Submittals: To facilitate a complete and thorough technical evaluation of proposals, it is imperative that preparation and technical submittals be in accordance with headings outlined in this specification. Pictures, design drawings and cut sheets of proposed turn-key system are required for evaluation. It is necessary that the proposal contains specific details on product being offered. Provide three complete sets of the proposed turn-key system. This will enable NNES to perform a thorough technical evaluation.
