This report presents findings of a survey of X-radiation emissions from color television receivers. The survey was undertaken after a pilot survey in Pinellas County, Florida, designed to measure the effectiveness of a shunt regulator correction program, indicated radiation emissions were occurring from components common to the industry. The purpose of this survey was to obtain information on the X-ray emission of television receivers of all manufacturers included in a sample of color television receivers in use in the homes of public health service employees in the Washington, DC area. Manufacturer representatives assisted in obtaining set identification and made measurements of the household line voltage and the operating high voltage in the television receivers examined. The representatives also replaced certain high voltage tubes and made other adjustments to reduce radiation emissions in any set exceeding the level recommended by the National Council on Radiation Protection and Measurements.
