The results of the various monitoring programs for 1998 indicated that radioactivity from the DOE's Idaho National Engineering and Environmental Laboratory (INEEL) operations could generally not be distinguished from worldwide fallout and natural radioactivity in the region surrounding the INEEL. Although some radioactive materials were discharged during INEEL operations, concentrations in the offsite environment and doses to the surrounding population were far less than state of Idaho and federal health protection guidelines. Gross alpha and gross beta measurements, used as a screening technique for air filters, were investigated by making statistical comparisons between onsite or boundary location concentrations and the distant community group concentrations. Gross alpha activities were generally higher at distant locations than at boundary and onsite locations. Air samples were also analyzed for specific radionuclides. Some human-made radionuclides were detected at offsite locations, but most were near the minimum detectable concentration and their presence was attributable to natural sources, worldwide fallout, and statistical variations in the analytical results rather than to INEEL operations. Low concentrations of 137Cs were found in muscle tissue and liver of some game animals and sheep. These levels were mostly consistent with background concentrations measured in animals sampled onsite and offsite in recent years. Ionizing radiation measured simultaneously at the INEEL boundary and distant locations using environmental dosimeters were similar and showed only background levels. The maximum potential population dose from submersion, ingestion, inhalation, and deposition to the approximately 121,500 people residing within an 80-km (50-mi) radius from the geographical center of the INEEL was estimated to be 0.08 person-rem (8 x 10-4 person-Sv) using the MDIFF air dispersion model. This population dose is less than 0.0002 percent of the estimated 43,7 00 person-rem (437 person-Sv) population dose from background radioactivity.

Every human is exposed to natural radiation. This exposure comes from many sources, including cosmic radiation from outer space, naturally-occurring radon, and radioactivity from substances in our bodies. In addition to natural sources of radiation, humans can also be exposed to man-made sources of radiation. Examples of man-made sources include nuclear medicine, X-rays, nuclear weapons testing, and accidents at nuclear power plants. The Idaho National Engineering Laboratory (INEL) is a U.S. Department of Energy (DOE) research facility that deals, in part, with studying nuclear reactors and storing radioactive materials. Careful handling and rigorous procedures do not completely eliminate the risk of releasing radioactivity. So, there is a remote possibility for a member of the public near the INEL to be exposed to radioactivity from the INEL. Extensive monitoring of the environment takes place on and around the INEL. These programs search for radionuclides and other contaminants. The results of these programs are presented each year in a site environmental report. This document summarizes the Idaho National Engineering Laboratory Site Environmental Report for Calendar Year 1995.

Scientists from the Environmental Science and Research Foundation, Lockheed Martin Idaho Technologies Company, the US Geological Survey, and other INEEL contractors monitored the environment on and around the INEEL to find contaminants attributable to the INEEL. During 1997, exposures from the INEEL to the public were found to be negligible. Pathways by which INEEL contaminants might reach people were monitored. These included air, precipitation, water, locally grown food (wheat, milk, potatoes, and lettuce), livestock, game animals, and direct radiation. Results from samples collected to monitor these pathways often contain radioactivity from natural sources and nuclear weapons testing carried out in the 1950s and 1960s, termed ''background radioactivity.'' According to the results obtained in 1997, radioactivity from operations at the INEEL could not be distinguished from this background radioactivity in the regions surrounding the INEEL. Because radioactivity from t! he INEEL wa s not detected by offsite environmental surveillance methods, computer models were used to estimate a radiation dose to people. The hypothetical maximum individual dose from the INEEL was calculated to be 0.03 millirem. That is 0.008 percent of an average person's annual dose from background radiation in southeast Idaho.

This report describes the calendar year 1998 compliance monitoring and environmental surveillance activities of the Lockheed Martin Idaho Technologies Company Environmental Monitoring Program performed at the Idaho National Engineering and Environmental Laboratory. This report includes results of sampling performed by the Drinking Water, Effluent, Storm Water, Groundwater Monitoring, and Environmental Surveillance Programs. This report compares the 1998 results to program-specific regulatory guidelines and past data to evaluate trends. The primary purposes of the monitoring and surveillance activities are to evaluate environmental conditions, to provide and interpret data, to verify compliance with applicable regulations or standards, and to ensure protection of public health and the environment. Surveillance of environmental media did not identify any previously unknown environmental problems or trends, which would indicate a loss of control or unplanned releases from facility operations. The INEEL complied with permits and applicable regulations, with the exception of nitrogen samples in a disposal pond effluent stream and iron and total coliform bacteria in groundwater downgradient from one disposal pond. Data collected by the Environmental Monitoring Program demonstrate that the public health and environment were protected.

This document provides a report and an analysis of the Radiological Control Program through the second quarter of Calendar Year 1998 (CY-98) for Lockheed Martin Idaho Technologies Company (LMITCO). LMITCO is the prime contractor at the Idaho National Engineering and Environmental Laboratory (INEEL). This Performance Indicator Report is provided in accordance with Article 133 of the INEEL Radiological Control Manual. The INEEL collective occupational radiation deep dose is 30.757 person-rem year to date, compared to a year to date goal of 47.0 person-rem. Overall, the site dose goal has been reduced. This is mainly due to work scope reductions at the Idaho Nuclear Technologies and Engineering Center (INTEC). However, due to unforeseen increases in shipments to the Radioactive Waste Management Complex, their goal has been raised to 9.60 person-rem to accommodate the increase in dose. The RWMC increase results in an increase to the LMITCO goal to 100.76f person-rem. The goal is not plotted in a linear fashion since work scope varies from quarter to quarter.
