OSHA recently announced revisions to its web page on ionizing radiation hazards. Highlights of the revised page include an online tool that focuses on radiation hazards and controls in the healthcare setting and a quiz that allows users to test their knowledge of radiation exposure, protection, and related OSHA standards. OSHA intends the revised page to be a starting point for technical and regulatory information regarding the recognition, evaluation, and control of workplace health hazards associated with ionizing radiation. The page focuses on ionizing radiation hazards that workers may encounter on a day-to-day basis.  Ionizing radiation sources can be found in occupational settings such as medical and dental offices, nuclear power plants, and air and space travel and transport operations. According to OSHA, exposure to ionizing radiation—especially at higher doses—increases the risk of developing health effects, which can include blood cell changes, skin burns, radiation sickness, cancer, and death.
