Описание (английский):

Relates to assemblies that are used to monitor clothing for radioactive contamination. Applies to monitoring that is performed after the clothing has been washed and prior to re-use to determine its acceptability for re-use.

Abstract

Overview

Key Topics

Scope of Application: The standard applies exclusively to laundered garments monitored within workplace settings. It is not intended for clothing used outside such environments.
Definitions and Terminology: IEC 61256 aligns with established terminology from the IEC International Electrotechnical Vocabulary (IEV) and other related standards, ensuring consistency in the concepts of activity, source efficiency, surface emission rate, and measurement error.
Classification of Monitors:
- By detected emission: alpha, beta, gamma, X-ray, or combinations
- By operation: fixed (stationary laundry during monitoring) or moving (laundry or detector moves)
- By background compensation: with or without ambient background correction
Design and Functional Requirements:
- Both sides of each garment must be monitored for certain contaminations
- Design must allow comprehensive coverage and ease of decontamination
- Emergency stop features are required for operator safety
- Specific indications (visual/audible) for normal operation, faults, and contamination alarms
- Detailed guidance for fault indication and maintenance support

Applications

IEC 61256:1996 is particularly valuable in environments where radioactive contaminants are present, and strict control over reusable personal protective equipment (PPE) is mandatory:

Nuclear Power Plants: Ensuring that laundered clothing is free of radioactive contamination before re-issue to staff.
Nuclear Research Facilities & Laboratories: Maintaining safe re-use practices for garments worn in controlled radiation areas.
Medical Facilities: Supporting nuclear medicine departments where staff clothing may encounter radioactive isotopes.
Industrial Radiography & NDT Companies: Monitoring reusable protective clothing for contamination in industrial settings where radiography is used.
Regulatory Compliance: Assisting organizations in meeting local and international regulations for radiation safety in the workplace.

By following IEC 61256, organizations can establish objective, repeatable processes for monitoring clothing, minimize false alarms, and improve overall radiation safety protocols.

Related Standards

IEC 50(393), IEC 50(394): Provide vocabulary relevant to nuclear instrumentation and radiation measurement.
IEC 359: Details performance testing and measurement of electrical and electronic equipment.
IEC 801: Addresses electromagnetic compatibility in process measurement and control.
ISO 8769: Specifies reference sources for calibration of surface contamination monitors (relevant for source efficiency and proper calibration).
IEC 181, IEC 181A: Covers classifications of electrical measuring apparatus used with ionizing radiation.

IEC 61256 should be used in conjunction with these related standards to ensure comprehensive radiation protection practices and harmonized technical terminology within the industry.
