Calculation of expected urinary and fecal excretion patterns using the ICRP task group on the human respiratory tract

Conference ·
OSTI ID:4311453
From third Health Physics Society midyear topical symposium; Los Angeles, California, USA (29 Jan 1969). See CONF-690103P1. Determination of the body burden of and prediction of the dose to an individual who accidentally inhales a predominantly alpha-orbeta-emitting radionuclide frequently rests on the interpretation of excretion data. In order to relate the excretion data to the actual inhalation, the report of the Task Group on Lung Dynamics for Committee II of the International Commission on Radiological Protection (ICRP) was used as the basis for the derivation of equations for the calculation of the urinary and fecal excretion patterns expected subsequent to an acute inhalation exposure to a radioactive aerosol. Because rapid interpretation of excretion data is often desirable, a computer code was developed which simplifies the application of the equations. The predicted excretion patterns are compared with excretion data from accidental human exposure cases. The effects of particle size and chemical state of the inhaled aerosol are examined, and the implications for in-plant air sampling and incident documentation are discussed. (auth)
