Paragraph 3: Specific provisions for mobile or portable equipment emitting ionising radiation

The provisions of this paragraph apply in the case of mobile or portable equipment emitting ionising radiation where the effective dose assessed at 1 metre from the source of ionising radiation is greater than 0.0025 millisieverts integrated over one hour. These provisions do not apply if the equipment is used in a fixed position or routinely in the same room or on the move.

I.-For the equipment mentioned in Article R. 4451-27, the employer shall identify and define an operating area such that the effective dose at its periphery remains below 0.025 millisieverts, integrated over one hour. II – When the equipment is used inside a supervised or controlled area already defined for another source of ionising radiation, the employer must adapt the definition of the operating area.

I – The employer shall restrict access to the operation zone to authorised workers only. II – The procedure used to identify each operating area and to define the technical and organisational measures adopted by the employer must be recorded in a form which allows consultation for a period of at least ten years.
