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. Therefore,
respect to radiation emission, a properly maintained and operated cabinet x-
ray system is a safe as a television or microwave oven.
