ERHS 515 - Non-Ionizing Radiation Safety

This course examines the safety requirements for non-ionizing radiation and how to address safe use of non-ionizing radiation producing devices. This includes tanning beds, ultra-violet light curing of materials, lasers used in entertainment, medicine and industry, and radiofrequency 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 these hazards, and will provide background on how these devices work, the associated biological effects and the basics of protection of workers and the public.

As non-ionizing radiation sources become more prevalent, especially laser and radiofrequency based devices, it is critical that we understand how they work, what the biological hazards are, and how to use them safely.

Class presentations will be streamed over the web and can be viewed live or at any time after the presentation by students using Windows Media Player.

Upon the completion of the course, students will be able to:

  • Use knowledge of mathematics, science, and applied sciences to determine exposure limits to all types of non-ionizing radiation
  • Design and/or conduct experiments that will result in the accurate characterization of non-ionizing exposures, and interpret the results of these surveys
  • Design a program to meet safety requirements for workers exposed to non-ionizing radiation
  • Solve problems from specific non-ionizing sources by applying scientific techniques
  • Understand the ethical problems facing a safety professional and ethical solutions
  • Discuss contemporary issues with non-ionizing radiation
