How harmfull laser radiation can be?
In my work there`s a machine that engraves things with laser... and the guy who installed it told us that it can`t work with it`s doors opened because it "could be harmfull for our health and even cause cancer".... and I was like 0_o Whooot?
I know my english is bad... so I apologize for that... I`m learnin, u know... =)
High doses of radiation can be harmful or even fatal. The damage caused by exposure to radiation is determined by the type of radiation, the duration of exposure, and the part of the body that is exposed. The effects of a radiation dose are either prompt or delayed. Prompt effects occur within the first several months after exposure. Delayed effects occur over many years. The delayed effects can include cancer or other diseases in exposed persons and harmful effects on unborn children.
It is important to note that an average of one in four people develops some form of cancer. Excess lifetime cancer risks resulting from exposure to radiation are calculated in addition to this number. Risk estimates assume that even small amounts of radiation pose some risk. That means even the door of that machine is always closed, the small dose of radiation "leaked" out of that machine may still pose long-term health risks if you stay near it for long hours consistently.

| | Laser Engraving $71.7 Laser engraving is the practice of using lasers to engrave or mark an object. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean engravings can be achieved at a high rate. The technique does not involve tool bits which contact the engraving surface and wear out. This is considered an advantage over alternative engraving technologies where bit heads have to be replaced regularly. The impact of laser engraving has been more pronounced for speciallydesigned laserable materials. These include polymer and novel metal alloys Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 84 Publication Date: 2010/04/24 Language: English Dimensions: 5.98 x 9.01 x 0.20 inches |
