Does projector gives off radiation?”, the answer is YES. However, their radiations pose little danger.
The projector emits a little radiation. The radiation of the projector is mainly light radiation and electromagnetic radiation. The strongest radiation is light radiation, but as long as the person is not in the range of the lens or faces the lens directly, it will not have much impact. The electromagnetic radiation of the instrument is very small and can be ignored.
Does the projector emit a lot of radiation?
The radiation of the projector is not particularly serious. The radiation of the projector is mainly composed of optical radiation and electromagnetic radiation, but although there is radiation, as long as the user operates in a standardized manner, the impact on the human body will not be too high. In general, projectors emit radiation, but the main radiation is light radiation. Users only need to avoid the lens, and they are basically not affected by any radiation.
There are many kinds of radiation, each with different principles, probably thermal radiation, electromagnetic radiation, nuclear radiation, ionizing radiation and so on. The intensity of any radiation is inversely proportional to the square of the distance, so if you’re really concerned, stay as far away as possible.
