What is a Cathode Ray Tube?
Cathode Ray Tube Material or “CRT Material” includes any or all of the following: • Cathode Ray Tube (“CRT”) – A CRT is a vacuum tube or picture tube used to convert an electrical signal into a visual image. A CRT becomes a waste when the owner discarded it or it is physically cracked, broken, or shattered. • Cathode Ray Tube Device (“CRT Device”) – A CRT Device is any electronic device that contains one or more CRTs including, but not limited to, computer monitors, televisions, cash registers and oscilloscopes. A CRT device becomes a waste when the owner discarded it or it is physically cracked, broken, or shattered. • Cathode Ray Tube Glass (“CRT Glass”) – CRT Glass means any glass released, derived or otherwise generated from the treatment or breakage of one or more CRTs. How much lead is in a CRT? A typical CRT contains between two to five pounds of lead in the thick glass picture screen. This lead serves to shield the viewer from radiation. Most CRTs exceed the regulatory threshol
A Cathode Ray Tube, abbreviated CRT , is the main component in a television and computer monitors display unit. The CRT is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. Phosphor screens using multiple beams of electrons have allowed CRTs to display millions of colors.
A cathode ray tube (CRT) is a type of analog display device. Cathode ray tubes are special, electronic vacuum tubes that use focused electron beams to display images. Though tubes of this type are used for many purposes, cathode ray tubes are most famous for their use in such things as televisions, oscilloscopes, computer and radar displays, and automated teller machines. Cathode ray tubes are also used in video game equipment. A cathode ray tube has a cathode or negatively charged terminal. In a cathode ray tube, this terminal is a heated filament, much like the filament seen in a light bulb. The filament is contained inside a vacuum within a glass tube. Inside the tube, a beam of electrons is allowed to flow from the filament into the vacuum. The flow of the electrons is natural, not forced. When used inside a television set, a CRT’s electrons are concentrated into a tight beam by a positively charged terminal, called an anode. An accelerating anode is then used to speed up the movem
