Dr. Whicker is regarded as one of the founders of Radioecology, the field addressing the fate and effects of radioactivity in the environment. His early work on fallout radionuclides in ecosystems had implications for health effects in human, plant and animal populations. His research in that field is known locally, nationally and internationally. His research on the effects of ionizing radiation on plants and animals has contributed to the development of national and international standards and guidelines for protecting the general environment from radioactive contamination.

His work on radionuclide transport processes has played a role in our understanding of mineral cycles and energy flows in terrestrial and aquatic ecosystems. DR. Whicker led the development of the PATHWAY foodchain transport model to predict internal doses from fallout radionuclides to residents of nine states nearest the Nevada Test Site. He also was a pioneer in using field measurement data to test the accuracy of computer models for prediction of radionuclide behavior in the environment. Additionally, Dr. Whicker helped pioneer the use of probabilistic uncertainty/sensitivity analysis in environmental transport and dose codes.

Research Interests

An independent & comprehensive risk assessment for public health and the environment & development of a risk-based decision analysis framework for the Los Alamos National Laboratory
