Full title and description
American National Standard — Inspection, Test, Construction, and Performance Requirements for Direct Reading Electrostatic/Electroscope Type Dosimeters (IEEE N322-1997). This standard specifies inspection, test, construction and performance requirements for direct-reading electrostatic/electroscope dosimeters used to measure personal dose equivalent or ambient exposure from external X‑ray and gamma radiation sources.
Abstract
The standard provides requirements and test procedures for direct-reading electrostatic/electroscope type dosimeters, including the testing of accessory electrometers or chargers used to operate or read these dosimeters. It is intended to ensure reliable measurement of accumulated exposure or dose equivalent from ionizing electromagnetic radiation (X‑rays and gamma rays).

Scope
This standard applies to direct-reading electrostatic/electroscope type dosimeters designed to measure personal dose equivalent or ambient exposure delivered by external ionizing electromagnetic radiation (X‑rays and gamma rays). It covers inspection, test, construction and performance requirements and gives procedures for testing dosimeters and accessory electrometers or chargers. The typical energy range addressed is approximately 20 keV to 3 MeV.
Key topics and requirements
- Definitions and classification of direct-reading electrostatic/electroscope dosimeters.
- Inspection and construction requirements to ensure mechanical and electrical integrity.
- Performance and accuracy requirements for measurement of personal dose equivalent and ambient exposure.
- Test procedures for energy response (approx. 20 keV to 3 MeV), leakage, stability, and environmental conditions.
- Requirements and test methods for accessory electrometers, chargers, and readout devices used with the dosimeters.
- Acceptance criteria and recommended calibration/verification practices for manufacturers and testing laboratories.
Typical use and users
The standard is used by dosimeter manufacturers, radiation instrument designers, radiation safety officers, calibration and testing laboratories, and facilities that perform personnel or environmental monitoring (including medical radiology, nuclear power, research, and industrial radiography). Products such as pocket pencil dosimeters commonly cite compliance with N322-1997 as part of their specification and acceptance testing.
Related standards
Related and complementary documents include other radiation-instrumentation standards in the N42 series and ANSI/IEEE radiation measurement specifications (for example ANSI N13.5 and various N42 standards dealing with dosimetry, calibration, and instrument performance). Users should consult the N42 committee publications for cross-references and modern companion documents.
