Описание (английский):

ISO 3925:2014 establishes the requirements for the identification and documentation of unsealed radioactive substances issued commercially by suppliers and which are intended for further handling or processing, either physical or chemical. Requirements for radiopharmaceuticals and standard sources are not covered.

Overview

EN ISO 3925:2015 (ISO 3925:2014) specifies requirements for the identification and documentation of unsealed radioactive substances that are commercially supplied for further physical or chemical handling. It applies to unsealed materials placed in containers (not sealed sources) and sets minimum labelling and certificate information to support safe use, traceability and radiological protection. Radiopharmaceuticals and standard sealed sources are excluded.

Key Topics

Definitions: unsealed radioactive substance, radionuclidic purity, radiochemical purity, specific activity, activity concentration.

Container identification requirements:

Manufacturer’s name or symbol
Chemical symbol and mass number of the radionuclide, and, where feasible, the chemical preparation name
Radiation symbol per ISO 361, and, if possible, the word “RADIOACTIVE”
Cross-reference to the supplier’s certificate

Certificate (manufacturer-supplied) must, as appropriate, include:

Manufacturer name and address; preparation name and chemical form; radionuclide identity and position in the molecule (if applicable)
Cross-reference to container label
Physical form, solvent, mass or volume
Activity concentration and/or specific activity at a stated time and date; for mixtures, activity of each radionuclide
Total activity at a stated time and date
Radionuclidic and radiochemical purity, chemical impurities, pH/acidity/alkalinity
Production and expiry dates, storage conditions, container characteristics and process batch identification

Applications

Suppliers and manufacturers of unsealed radioactive substances use the standard to produce compliant labels and certificates.

Laboratories, research facilities and industrial users rely on the required documentation for safe handling, dose calculations, quality control and regulatory compliance.

Radiation protection officers, procurement teams and auditors use EN ISO 3925:2015 to verify traceability, purity specifications and storage/expiry information before processing or chemical manipulation.

Benefits

Improves safety and radiation protection by ensuring clear hazard identification.

Enhances traceability, quality assurance and inventory control for unsealed radioactive materials.

Facilitates consistent supplier-to-user communication of activity, purity and chemical form - critical for measurements, processing and waste management.
