Computer/VDT Screens

Computer/VDT Screens: "Q:





I have a colleague who is pregnant and who types at a computer. How much radiation does her baby receive at a typical computer? Is there a lead shield that she could wear? Like an apron?

A:





Regulations of the US Department of Health and Human Services require manufacturers to test computer monitor emissions for radiation and to label them attesting to the fact that they have been found to meet the standards of Title 21 of the Code of Federal Regulations. You should be able to find this label on the rear of the computer monitor or the computer processor. Health studies of pregnant women who work with VDTs have not found harmful effects on the women or on their children. Heavy lead aprons or other shields are not considered necessary for units that meet the x-ray emission standards of 21CFR. Such shields may actually be counterproductive from an ergonomic point of view. "
