The Anticipated Hazards Due to Errors In Using Laser In Medicine & Recommendationms for the Safe Use Of Medical Laser Systems in Iraqi Hospitaals

Abstract

• Causes of Laser Hazard I - Inherent Hazards to Laser Beam Direct or reflected laser beams have consequential health effects range from minor skin burn to irreversible eye injuries. The hazards depend on the power output and wavelength of the used laser and depend on the exposure time and MPE. ti & 2) A- Eye Hazards Point light source cause more damage to eyes than large sources, because point sources concentrate into a very small point on the retina with a high power density. So direct laser beam or specular reflected laser beam cause more damage than diffusely reflected laser beam.
