RAC is returning to Washington, D.C., for a second year to present the most comprehensive one week course offered in environmental radiological risk assessment. The course schedule has been updated based on feedback from participants and includes even more case studies and problem solving sessions. Course material will stress the practical application of the latest methods used in environmental radiological risk assessment, including the use of computer modeling for risk assessment. Participants will receive a copy of the text book Radiological Risk Assessment and Environmental Analysis, published by Oxford University Press and edited by course presenters John E. Till and Helen A. Grogan. This publication will be used as a primary reference text in addition to other materials provided at the course.
