TAILIEUCHUNG - TRITIUM MEASUREMENT TECHNIQUES - NCRP REPORT No.125

The development of a respiratory tract model which accurately reflects reality is a difficult and complicated effort. This stems largely from the variety of airway shapes, airflow patterns, and cell types having different radiosensitivities. Anatomic and physiologic alterations in smokers or those exposed to chemicals, among others, further complicate modeling. In spite of the inherent difficulties, the continuing pursuit of a model that mimics actual conditions has been considered to be important by those involved in radiation protection | NCRP REPORT No. 125 DEPOSITION RETENTION AND DOSIMETRY OF INHALED RADIOACTIVE SUBSTANCES Recommendations of the NATIONAL COUNCIL ON RADIATION PROTECTION AND MEASUREMENTS Issued February 14 1997 National Council on Radiation Protection and Measurements 7910 Woodmont Avenue Bethesda MD 20814-3095 LEGAL NOTICE This report was prepared by the National Council on Radiation Protection and Measurements NCRP .
