IMPLICATIONS OF PATHWAY ANALYSIS OF DEMINIMUS CONCENTRATIONS OF RADIOACTIVE WASTE.

This paper presents the results of pathway analysis performed to assess the possible exposures resulting from the disposal of waste which may contain small quantities of artificially produced or enhanced radioactivity into sanitary landfill sites. The four pathways considered are external exposure, dust inhalation, food, and water ingestion. The proposed level of 100 pCi/g as the limit below which waste would be considered nonradioactive was found to produce a dose rate to members of the critical group of less than the suggested minimus level of 10 mrem/a**1 under conservative exposure conditions, and less than 1 mrem/a**1 with more realistic assumptions.
