EDLL 2006 - Non-Ionizing Radiation Safety

  • 4.5 CEUs

The use of non-ionizing radiation has become so common in both the workplace and home that we seldom notice its presence. The safe use of non-ionizing radiation relies on knowledge of a broad array of standards and recommendations, and oftentimes calculations are needed to simply determine the maximum amount of exposure permitted.

This course examines the safety requirements for non-ionizing radiation and how to address safe use of non-ionizing radiation producing devices. This includes ultra-violet light materials curing, lasers used in entertainment medicine and industry, and radio frequency sources such as WiFi networks, cell phones and industrial heat sealers.

The class is designed for students who have little or no experience in evaluating non-ionizing radiation hazards. It will provide background on how the devices work, the associated biological effects and the basics of protection of workers and the public.

Upon completion of the class you will be able to determine the applicable safety standards for ultraviolet light, broadband light, lasers, radio frequency radiation and static magnetic fields.
