25 Special precautions to be taken with irradiating apparatus used in diagnosis

• No person shall use an irradiating apparatus for any diagnostic purpose unless it is fitted with such means of restricting the direction and size of the radiation beam as will ensure that the minimum practicable area of the person examined is irradiated, and is fitted with a filter such as will reduce the radiation dose to that area to the minimum consistent with obtaining the diagnostic information required.
