Control the laser beam hazards for class IIIB and IV laser is concluded: engineering and executive controls. In executive control, when laser beam enters to the free space, the controlled area must be identified to protect people and control the radiation exposure limits. Given the fact that the laser light of the laser is entering the environment, the identification of the area under control is necessary and the traffic must be controlled in accordance with certain criteria. By limiting the region where the radiation density is greater than the radiation limits, restrictions can be applied in a smaller space. Due to space constraints in such centers, determining the boundaries of the risk zone is appropriate methods. By specifying this area and observing the rules and regulations, it is possible to prevent radiation damage caused by the laser beam and its reflections.
