At ChemRisk, Tom Widner is responsible for designing, conducting, and managing programs and technical studies addressing environmental and occupational impacts of radioactive materials and chemical agents. He has more than 20 years of professional experience in health physics and occupational health. Tom has served as project manager and principal investigator on three of the nation's largest dose reconstruction projects, leading teams of scientists and engineers independently evaluating public health impacts from past releases of radionuclides and chemicals from U.S. nuclear weapons facilities. Teams led by Tom have advanced the state of the art for health assessment in the application of screening techniques, an iterative assessment approach, predetermined decision criteria, uncertainty analyses, simultaneous evaluation of risks from chemicals and radionuclides, and innovative public involvement. Tom has performed comprehensive assessments of releases of radionuclides (including radioiodine, tritium, cesium-137, strontium-90, cobalt-60, ruthenium-106, zirconium-95, niobium-95, cerium-144, americium-241 and various isotopes of plutonium, uranium, and thorium) and carcinogenic and noncarcinogenic chemicals and metals (most notably mercury, PCBs, organic solvents, and beryllium). He has worked closely with representatives of the U.S. Department of Energy, the Centers for Disease Control and Prevention, and the state health departments of Colorado and Tennessee.
