Is Exposure To Projector Ray Harmful To The Body? by pheesayor(m): 1:38pm On Jul 14, 2012 |
Projectors are becoming popular in schools and churches, particularly for schools who use interactive boards and have to stand in front of the projectors to use the board. I want to know if continued (and unavoidable for teachers using it) exposure to the rays causes any harmful health effects. Thanks |

Short answer is no. The danger posed by rays depends on the ray's wavelength and frequency. The higher a ray's frequency and the shorter its wavelength, the more dangerous it is. Essentially, a ray will be dangerous to humans if it can penetrate a human’s living tissue and interact with molecules therein. 1 Like |
