Full title and description

ISO 1677:1977 — Sealed radioactive sources — General. This International Standard provided short-form general requirements and definitions for sealed radioactive sources, intended as an early baseline document for classification and basic production/marking considerations for sealed sources used in industry, medicine and research.

Abstract

ISO 1677:1977 was the first-edition ISO document giving general guidance on sealed radioactive sources. It set out basic objectives for ensuring containment of radioactive material in sealed sources and introduced terminology and high-level expectations that were later expanded into a more comprehensive series. The standard has since been withdrawn and superseded by the ISO 2919 series of standards.

General information

• Status: Withdrawn / superseded.
• Publication date: June 1977 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.280 — Radiation protection / sealed sources.
• Edition / version: 1 (1977).
• Number of pages: 3 pages (as listed on ISO bibliographic record).

Scope

ISO 1677:1977 addressed general requirements and terminology related to sealed radioactive sources — devices in which radioactive material is permanently sealed in a capsule or closely bonded and in which the capsule is strong enough to prevent leakage of radioactive material under normal conditions of use. The standard functioned as a short, general reference prior to the adoption of the more detailed ISO 2919 series.

Key topics and requirements

• Definitions and terminology for sealed radioactive sources (classification groundwork).
• High-level containment and production expectations for preventing release of radioactive material.
• Basic marking and documentation concepts to support traceability and regulatory control (brief treatment; later expanded in ISO 2919).
• Foundational concept of performance-based testing (later implemented in detail by ISO 2919 test schedules).

Typical use and users

ISO 1677:1977 was aimed at manufacturers of sealed radioactive sources, regulatory bodies and users in medical, industrial and research institutions that employ sealed sources for measurement, radiography, calibration and therapy. After withdrawal, users rely on ISO 2919 (and related national/regulatory documents) for current requirements.

Related standards

ISO 1677:1977 has been withdrawn and its subject matter incorporated and greatly extended by ISO 2919 (Radiation protection — Sealed radioactive sources — General requirements and classification), with later editions in 1999 and 2012 (current edition). Other related documents include ISO and national standards and regulatory guidance on leak testing, transport and handling of radioactive material and IAEA safety guides covering sealed sources.

FAQ

Q: What is this standard?

A: ISO 1677:1977 is an International Organization for Standardization document titled "Sealed radioactive sources — General" (first edition, June 1977). It provided a short set of general requirements and definitions for sealed radioactive sources.

Q: What does it cover?

A: It covered high-level, general matters for sealed radioactive sources — basic terminology, containment objectives, and introductory marking/production considerations. The detailed performance, testing and classification requirements were later developed in ISO 2919.

Q: Who typically uses it?

A: Historically: manufacturers of sealed sources, regulators and organizations that design or use sealed sources (medical, industrial, research). Today those users consult ISO 2919 and applicable national regulations instead.

Q: Is it current or superseded?

A: ISO 1677:1977 is withdrawn and superseded — its subject matter was revised and replaced by ISO 2919 (subsequent editions in 1980, 1999 and 2012). Users should follow the latest edition of ISO 2919 for current, authoritative requirements.

Q: Is it part of a series?

A: Not as a continuing series; ISO 1677 was an early standalone standard later incorporated into the ISO 2919 family, which is the active series covering sealed radioactive source classification and testing.

Q: What are the key keywords?

A: Sealed radioactive source; classification; containment; leak testing; marking; radiation protection; ISO 1677; ISO 2919.
