Introduction to health hazards from UV, optical laser hazards, infrared radiation, radio-frequency radiation, heat stress, electrical shock, electric and magnetic fields. Application of current standards for these physical agents. Emphasis on occupational hazards with additional discussion of environmental exposures where appropriate. Offered: odd years; W.
Class description
Students will become familiar with basic concepts of electrical safety, the known health effects of exposure to electromagnetic energy, and appropriate safety precautions. We use examples drawn from many common sources, such as lasers, ultraviolet lamps, the sun, and radio transmitters. We also discuss controversial topics, such as the literature on health effects of electric and magnetic fields created by power lines and cellular telephones.
Student learning goals
General method of instruction
The class is presented in a lecture format, with discussion following the lecture.
Recommended preparation
Basic knowledge of physics and principles related to electricity and magnetism. Students should be familiar with biological processes and basic human organ systems (E.g. heart, eyes, nervous system, etc.).
Class assignments and grading
Students complete three problem sets in addition to the midterm and final exam. Emphasis is on simple quantitative estimates of exposure and comparison with national or international safety standards to assess the potential hazards.
Problem sets (30%), midterm (20%), final exam (40%), participation in class discussion (10%)
