Video display products that contain cathode ray tubes (CRTs) can give off x-rays. The CRT is a specialized vacuum tube that receives and displays images on an electronic screen. Most modern computers monitors and televisions (TVs) today use liquid crystal display (LCD), Light-emitting diodes (LED), or plasma.
In the early 1960s, some TVs with CRTs were found to emit excessive x-radiation, and a federal performance standard was created to protect the public from this hazard. Today, electronic technology for TVs and computer monitors with CRTs has changed so drastically that the level of risk of x-ray exposure is almost non-existent. Manufacturers of products that use CRTs must certify that their products comply with the federal performance standard for the life of the product.
TV receivers and computer monitors containing CRTs no longer pose a risk of emitting excessive x-radiation. Since the creation of the federal performance standard, the FDA has tested hundreds of TV receivers and computer monitors and rarely encountered any that were unsafe.
