Another course built for the International Atomic Energy Agency (www.iaea.org) in the 3rd year of actively consulting the agency and creating courses for the needs of Nuclear Medicine Sector. Fourth course published, and five more to be published soon, is the result of our collaboration. This course explains the eight best practices referred to radiation exposure. This course had an instructional designer working with me, so we built this for 10 working days. The layout fits in the previously set standards for the eLearning courses I build for the agency.
