YY 0318-2000Protective device against diagnostic medical X-radiation - Part 3: Protective clothing and protective devices for gonads (English PDF)

Foreword

This Standard is identical to the International Electrotechnical Commission IEC 61331-3:1998 "Protective devices against diagnostic medical X-radiation - Part

This Standard is formulated so that there is a unified requirement for protective device against diagnostic medical X-radiation in the manufacturing and quality inspection, to ensure and improve the quality of the product, to ensure safety and effectiveness.

For the protection against diagnostic medical X-radiation, in addition that the X- ray machine's own design must meet the requirements of the standard, in the practice of radiation, necessary additional protective measures shall be provided for X-radiation. Additional protections are generally divided into appliance category and device category. The appliance category includes protective chambers and protective screens, etc. The device category includes protective aprons, protective clothing, and protective gloves, etc. This Standard only involves protective devices.

As protection, it shall not be understood as just the protection of the operator.

At the same time, the protection of the patient shall be fully considered. This is a problem that cannot be ignored.

From the date of implementation, this Standard replaces the protective devices (aprons and gloves) with the same names in YY 0128-1993 "Protective appliance and device against diagnostic medical X-radiation".

Compared with the gloves and aprons in the YY 0128-1993 standard, the protective gloves and aprons in this Standard have the following main changes.

1. Protective gloves

1) It is stipulated that the lead equivalent is not less than 0.25 mmPb. The previous standard stipulates that, the lead equivalent is 0.25 mmPb, 0.35 mmPb, and 0.5 mmPb; and the deviations are given.

2) Delete the requirements for elongation-flexion life and physical properties; only give a qualitative requirement.

3) There are still three specifications. But the overall sizes have been adjusted. In terms of varieties, add the protective mitten.

2. Protective aprons

1) CHANGE from the previous three specifications to four types.

2) Adjust the specific dimensions.

3) Delete the requirements for physical properties; only give a qualitative requirement.

4) For different areas of protection, specify different minimum attenuation equivalents.

5) Stipulate the standard sizes of protective aprons; subdivide the large, medium and small sizes, which is more suitable for the needs of different people.

This Standard is Part 3 under the general heading of protective device against diagnostic medical X-radiation. Under this general heading, it includes three parts.

Part 1: Determination of attenuation properties of materials Part 2: Protective glass plates Part 3: Protective clothing and protective devices for gonads Annexes A and B in this Standard are all informative annexes.
