Scope

1.201 Scope
This Collateral Standard applies to medical diagnostic X-RAY EQUIPMENT and
to sub-assemblies of such EQUIPMENT.
1.202 Object
The object of this Collateral Standard is to establish general requirements for
protection against IONIZING RADIATION in medical diagnostic X-RAY
EQUIPMENT, in order that the DOSE EQUIVALENT to the PATIENT, the
OPERATOR and other staff can be kept as low as reasonably achievable.
Some of the requirements in this Collateral Standard include variations for
different types of X-RAY EQUIPMENT. This is intended to widen the scope
within which the Collateral Standard can be applied usefully without addition or
modification, especially in respect of types of X-RAY EQUIPMENT that are
commonly used in MEDICAL DIAGNOSTIC RADIOLOGY.
The requirements in this Collateral Standard apply mainly in respect of X-
RADIATION after its generation. Requirements for the control of the electrical
energy used to generate X-RADIATION, which is also an important aspect of
RADIATION PROTECTION, are included in GB 9706.1 “Medical electrical
equipment - Part 1. General requirements for safety” and in Particular
Standards for the safety of the EQUIPMENT concerned.
