Further advice on these aspects can be found in ICRP Publications 33[15], 34[16], 60[17], 73[18], 85[21], 87[22] and 93[23]. Readers of this collateral standard are reminded that, in accordance with IEC 606011, Clause 5, all the test procedures described are TYPE TESTS, intended to be carried out in a dedicated testing environment in order to determine pliance. Tests to be carried out b y MANUFACTURERS to ensure pliance during production or installation and tests for detecting nonpliance subsequently to delivery, are not included. ————————— 1) Figures in square brackets refer to the Bibliography. BS EN 6060113:2020 – 8 – MEDICAL ELECTRICAL EQUIPMENT – Part 13: General requirements for basic safety and essential performance – Collateral Standard: Radiation protection in diagnostic Xray equipment 1 Scope, object and related standards Scope This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, hereafter referred to as ME EQUIPMENT and ME SYSTEMS. This collateral standard applies to XRAY EQUIPMENT and to subassemblies of such equipment, where RADIOLOGICAL IMAGES of a human PATIENT are used for diagnosis, planning or guidance of medical procedures. Object The object of this collateral standard is to specif y general requirements that are in addition to those of the general standard and to serve as the basis for particular standards. The object of this collateral standard is to establish general requirements for protection against XRADIATION in XRAY EQUIPMENT, in order that the IRRADIATION of the human PATIENT, the OPERATOR, staff and members of the public can be kept as low as reasonably achievable, without jeopardizing the benefit of the RADIOLOGICAL procedure. Particular standards may specif y their appropriate values and/or measures for general requirements specified in this collateral standard. The implementation of the general requirements or the reference to the particular standard instead, shall be justified in the RISK MANAGEMENT process. This collateral standard considers RADIATION PRO TECTIO N aspects related to X RADIA TIO N only. Requirements for the control of the electrical energy used to generate XRADIATION, which is also an important aspect of RADIATION PROTECTION, are included in IEC 606011 and in particular standards for the safety and ESSENTIAL PERFORMANCE of the EQUIPMENT concerned. Related standards IEC 606011 For ME EQUIPMENT and ME SYSTEMS, this collateral standard plements IEC 606011. W hen referring to IEC 606011 or to this collateral standard, either individually or in bination, the following conventions are used: ? the general standard designates IEC 606011 alone。 = dK dt Unit: J kg–1 s–1 If the special name gray is used, the unit of AIR KERMA RATE is gray per second (Gy s–1) (ICRU 60) [20] [IEC 60580:2020, definition ] [8] AM BIENT DOSE EQUIV ALENT H*(d) at a point in a RADIATION FIELD, the DOSE EQUIVALENT that would be produced by corresponding expanded and aligned field, in the ICRU sphere at a depth, d, on the radius opposing the direction of the aligned field Unit: J kg–1 The special name for the unit of AMBIENT DOSE EQUIVALENT is sievert (Sv) (ICRU 51)[19] ATTENU ATION reduction of a RADIATION QUANTITY upon passage of the RADIATION through matter resulting from all types of interaction with this matter NOTE The RAD I A T I ON QUA NTITY may be, for example, the particle flux density or the energy density.
