Dr. Kocher has extensive experience in environmental health physics and assessments of dose and risk from exposure to ionizing radiation, involving the development and application of models and databases for assessing radiation doses to the public due to radionuclides in the environment and health risks due to exposure to different radiation types, and evaluations of dose and risk assessment models for regulatory and decision-making purposes.
Dr. Kocher was principal author of a study for The National Institute for Occupational Safety and Health (NIOSH) to evaluate dose and dose-rate effectiveness factors (DDREFs) for low-LET radiation. These DDREFs are
incorporated into cancer risk models in the Interactive RadioEpidemiological Program (IREP). Dr. Kocher’s work on assessing the biological effectiveness of different radiation types and their uncertainties was an important contribution to the development of IREP. He was also principal investigator for the Defense Threat Reduction Agency (DTRA) to develop improved models and methods of uncertainty analysis for use in dose reconstructions.
For several advisory groups for Federal agencies and committees of the National Academy of Sciences (NAS) and National Council on Radiation Protection and Measurements (NCRP), Dr. Kocher contributed to:
Dr. Kocher has been a frequent consultant to the International Atomic Energy Agency on issues of radioactive and hazardous chemical waste management and protection of the environment.
