Full title and description

IEC/TS 62743:2012 — Radiation protection instrumentation — Electronic counting dosemeters for pulsed fields of ionizing radiation. This Technical Specification defines test procedures, performance criteria and additional requirements for counting dosemeters when operated in pulsed radiation fields to ensure correct measurement of single and repeated radiation pulses and to treat pulsation as an additional influence quantity.

Abstract

This technical specification applies to all types of electronic counting dosemeters regardless of measured quantity or radiation type. It addresses the particular challenges of pulsed ionizing radiation (single pulses and repeated pulses), specifying parameters to be known for the radiation field, parameters to be determined for the dosemeter, test methods and pass/fail criteria. Annexes provide parameter values for typical workplaces and definitions for characterizing pulsed fields.

Scope

Specifies additional tests and requirements for counting dosemeters when used in pulsed ionizing radiation fields. The TS supplements existing dosemeter standards by treating pulse duration, repetition and pulse-related influence quantities (for example pulse amplitude, energy and incidence direction) and by defining measurement and acceptance criteria for single-pulse and pulsed-field performance. It does not replace continuous‑field requirements but provides the additional checks necessary for accurate pulsed-field dosimetry.

Key topics and requirements

• Definition of pulse-field parameters and recommended test conditions (pulse duration, repetition rate, pulse shape, energy spectrum).
• Requirements to ensure correct detection and counting of a single radiation pulse even when the dosemeter is in background-measurement states.
• Performance criteria for repeated pulses (expected performance between single-pulse and continuous radiation conditions).
• General test procedures and reference/standard test conditions for laboratory evaluation.
• Radiation detection requirements, environmental, mechanical and electromagnetic compatibility (EMC) requirements specific to pulsed fields.
• Documentation requirements and informative annexes with parameter values for typical workplaces where pulsed radiation occurs.

Typical use and users

Used by manufacturers of personal and area electronic counting dosemeters, test laboratories performing type and conformity testing, radiation protection officers, dosimetry service providers, accelerator and industrial radiation facility engineers, and regulatory/conformity assessment bodies responsible for acceptance of dosimetry equipment in pulsed radiation environments (e.g., accelerators, pulsed X-ray sources, certain medical and industrial systems).

Related standards

Complements and is intended to be used alongside general dosimetry and radiation-protection instrument standards such as IEC 61526 (electronic personal dosemeters), IEC 60846 series (instrumentation), relevant ISO standards for radiation fields (for example ISO 4037 series) and national/adopted variants or published PD/BS versions where applicable. National adoptions and published drafts (PD/IEC/TS variants) exist from multiple standards bodies.
