Potential Dose 1
Potential Dose 1 : Radiation and Radiological Disasters. (a) An exposure value multiplied by a contact rate (e.g., rates of inhalation, ingestion, or absorption through the skin) and assumes total absorption of the contaminant. [NRC, 1991: Human Exp. For Airborne Pollutants]; (b) The amount of a chemical contained in material ingested, air breathed, or bulk material applied to the skin. [USEPA, 1992: GL for Exposure Assessment] [USEPA, 1992a: Dermal Exposure Assessment] [REAP, 1995: Residential Exposure Assessment Project] [USEPA, 1997b: Exposure Factors Handbook]; (c) The amount of a compound contained in material swallowed, breathed, or applied to the skin. Potentially Responsible Party (PRP): Any individual or company__including owners, operators, transporters or generators__potentially responsible for, or contributing to a spill or other contamination at a Superfund site. Whenever possible, through administrative and legal actions, EPA requires PRPs to clean up hazardous sites they have contaminated. [USEPA, 1997a: EPA Terms of Environment]; (d) The amount of chemical that could be inhaled without wearing a respirator, or which could be deposited on the skin without wearing clothing. Potential dose is typically expressed as a mass per unit body weight per unit time (i.e., mg/kg/day). [USEPA, 1998: Postapp. Exposure Test GL.]
