A significant part of the Department's work involves developing, applying and maintaining the models or tools to estimate these radiation doses. We provide a range of scientific and technical research, training and software products to government, industry and others. Areas covered include emergency planning and response, permitted releases of radionuclides into the environment and solid waste management disposal, contaminated land and transport of radioactive waste.
