Abstract
This PEP course illustrates practical applications of the International Commission on Radiological Protection Publication 66 Human Respiratory Tract Model (HRTM) (ICRP 1994). Radiological dose assessment examples include implementation of new software developed for the U.S. Department of Energy and the National Institute for Occupational Safety and Health /Office of Compensation Analysis and Support (OCAS). Industrial hygiene examples include respiratory tract deposition of beryllium and anthrax. We will assume that attendees have taken an introductory PEP on the HTRM or are otherwise familiar with its basic characteristics. The new HTRM is a general update of the Lung Model in ICRP Publication 30 (ICRP 1979) for adult workers, and is significantly broader in scope. It applies explicitly to workers and all members of the public, for (1) inhalation of particles, gases and vapors; (2) evaluation of dose (or material retention) in sensitive regions of the respiratory tract, for a given intake or exposure, and; (3) interpretation of bioassay data. The HTRM provides a physiologically realistic framework for modeling respiratory tract retention and excretion characteristics, and the resulting respiratory tract and systemic organ doses. It enables knowledge of the aerosol characteristics, dissolution and absorption behavior of specific materials to be used in a realistic manner, and calculates meaningful doses in relation to the morphological, physiological, and radiobiological characteristics of the various tissues of the respiratory tract. Approaches for obtaining needed aerosols properties will also be illustrated in this PEP course.
