Radiation Safety Information
Federal, State and Local Radiation Regulations (US ONLY)
This cabinet x-ray system was designed to conform to U.S. and Food
and Drug Administration (FDA) requirements as stated in the Code of
Federal Regulations, Title 21 (21CFR). These requirements (often
referred to as the CDRH or BRH regulations) govern the design and
manufacture of all equipment that produces ionizing radiation. Such
equipment includes television sets and microwave ovens, as well as
cabinet x-ray systems. In fact, the maximum allowable radiation
emission for cabinet x-ray systems is the same as that set for
television sets and microwave ovens.
