| Abstract | ||
| The use of lasers by industry and by the academic community continues to increase. Many educational institutions are using a wide variety of lasers in many different ways. Traditional disciplines in universities, colleges and high schools, such as biology, chemistry, and physics, now recognize the laser as an essential teaching element. Unique environments associated with educational institutions (such as civil engineering, earth and planetary sciences, and biomedical research) have also incorporated lasers into their educational processes. The effects of CO2 laser hazard on different parts of human body (such as eye and skin) have been studied, where hazards are classified into direct and indirect exposure of laser radiation. The nominal hazard zone has been calculated; it was compared with power and the maximum permissible exposure and found that the nominal hazard zone was direct proportional to power and inverse proportional to maximum permissible exposure. The optical density has been calculated; it is also compared with maximum permissible exposure and found that the optical density was inverse proportional to the maximum permissible exposure. | ||
