Title: Dose assessment of an accidental exposure at the IPNS

Abstract

Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose ranged from 550 mrem/min to 2850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min. Assumed and measured quality factors ranged from 2.6 to 11.8. Cytogenetic analyses of blood samples detected no positive exposure. The recommended TEDE rate was 158 mrem/min. The TEDE was 750 mrem.

  • Seven different methods were used to estimate the dose rate to a female worker who was accidentally exposed in the neutron PHOENIX beamline at the IPNS. Theoretical and measured entrance dose rates ranged from 550 mrem/min to 2,850 mrem/min. Theoretical estimates were based on a Monte Carlo simulation of a spectrum provided by IPNS (Crawford Spectrum). Dose measurements were made with TLDs on phantoms and with ionization chambers in a water phantom. Estimates of the whole body total effective dose equivalent (TEDE) rate ranged from 5.2 mrem/min to 840 mrem/min.

    A quantitative assessment was performed of the risk of lung cancer from exposure to cadmium (7440439) in a population of workers at a facility that processed cadmium metals and compounds. The population consisted of all workers who worked in a production area for at least 6 months from 1940 through 1969; the vital status of the workers was updated through 1984. A total of 606 white male workers, contributing 16,898 person years and 162 deaths were analyzed. A statistically significant dose response was evident in nearly all of the Poisson regression models evaluated. A nearly significant excess in mortality frommore » lung cancer was noted for the entire cohort. Mortality from lung cancer was significantly elevated among non Hispanic workers, workers in the highest cadmium exposure group, and among workers with 20 or more years since first exposure. Based on these analyses, the lifetime excess lung cancer risk at the current OSHA standard for cadmium fumes of 100 micrograms per cubic meter was estimated to be approximately 50 to 111 lung cancer deaths per 1000 workers exposed to cadmium for 45 years. The authors conclude that efforts should be made to further reduce the risk by lowering occupational exposures to cadmium to the lowest level feasible.« less

  • A project investigated the development of dose-duration-response information for short-term exposure to hydrogen chloride. The approach is one alternative for providing the risk assessor/risk manager a readily available guide for decision making with respect to short-term exposure to hydrogen chloride. The objectives of the project were to provide a detailed analysis of the health effects associated with short-term exposure to hydrogen chloride and to propose an approach for evaluating the hazard to humans exposed to hydrogen chloride for short periods of time.

  • The objective of Task 7.lD was to (1) establish a collaborative US-USSR effort to improve and validate our methods of forecasting doses and dose commitments from the direct contamination of food sources, and (2) perform experiments and validation studies to improve our ability to predict rapidly and accurately the long-term internal dose from the contamination of agricultural soil. At early times following an accident, the direct contamination of pasture and food stuffs, particularly leafy vegetation and grain, can be of great importance. This situation has been modeled extensively. However, models employed then to predict the deposition, retention and transport ofmore » radionuclides in terrestrial environments employed concepts and data bases that were more than a decade old. The extent to which these models have been tested with independent data sets was limited. The data gathered in the former-USSR (and elsewhere throughout the Northern Hemisphere) offered a unique opportunity to test model predictions of wet and dry deposition, agricultural foodchain bioaccumulation, and short- and long-term retention, redistribution, and resuspension of radionuclides from a variety of natural and artificial surfaces. The current objective of this project is to evaluate and validate pathway-assessment models applicable to exposure and dose reconstruction at DOE facilities through use of international data sets. This project incorporates the activity of Task 7.lD into a multinational effort to evaluate models and data used for the prediction of radionuclide transfer through agricultural and aquatic systems to humans. It also includes participation in two studies, BIOMOVS (BIOspheric MOdel Validation Study) with the Swedish National Institute for Radiation Protection and VAMP (VAlidation of Model Predictions) with the International Atomic Energy Agency, that address testing the performance of models of radionuclide transport through foodchains.« less

  • Exposure scenarios are defined to identify potential pathways and combinations of pathways that could lead to radiation exposure from immobilized tank waste. Appropriate data and models are selected to permit calculation of dose factors for each exposure
