Peoples Republic of China National Standard Laser Radiation Occupational Health Standard

摘要

As far as the long term exposure to laser radiation of a certain strength by laser workers is concerned, it is possible for it to give rise to reductions in visual acuity, clouding of lenses, as well as headaches, anemia, nerve weakness, and other similar bad effects throughout the entire body. The potentially problem causing laser radiations are capable of leading to severe acute disorders. Because of this, personnel in contact with lasers (exclusive of those receiving laser diagnosis and treatment) should receive strengths of radiation which are definitely limited. The maximum permissible amounts of radiation (or degree of radiation) are not only related to wavelength, but also, have a close relationship with the duration of the radiation received. The maximum permissible amounts of radiation for the human body (MPE) take the two organs of the eyes and the skin as the standards.
