Answer to Question #1186 Submitted to "Ask the Experts"Category: Lasers The following question was answered by an expert in the appropriate field: Q
What are the health risks, if any, to residents who live as near as 200 feet from a fiber optic amplification facility and what would these risks involve?
A
This Health Physics Society Web site deals with matters related to radiation safety. Types of radiation include ionizing radiation such as x rays and gamma rays and nonionizing radiation such as radiofrequency signals, ultraviolet light, and lasers. Lasers are the only type of radiation source generally present in a fiber optics telecommunications system. Specifically, most fiber optics telecommunications systems utilize infrared laser light, and the light is contained within the optical fiber systems and does not present an external hazard.
