Amendment 1-1983

This document represents the first amendment issued to the international standard designated ISO 4037:1979. It serves as an official modification intended to update, clarify, or revise specific technical provisions within the original normative text. Adopted and published by a prominent global standards development organization, this amendment establishes a formal mechanism for maintaining the currency and relevance of radiation protection and safety guidance related to x- and gamma-ray reference radiations for dosimetry. The content focuses on technical adjustments rather than broad policy changes, ensuring that measurement protocols and reference conditions remain consistent with evolving scientific understanding. It is designed to be used in conjunction with the base standard, providing necessary corrections or additions that must be integrated into existing applications. The amendment is structured to facilitate global harmonization, allowing professionals in radiation dosimetry to align their practices with the updated requirements. All technical content within this document is strictly procedural and technical, aimed at improving measurement accuracy and safety without altering the fundamental scope of the original standard.
