ASTM D2334-88e1 PDF

Full title and description

St ASTM D2334-88e1 — Test Methods for Radioactive Iodine in Water. This designation (D2334-88E01) is an ASTM test-method document that describes laboratory procedures for the collection, chemical separation and measurement of radioactive iodine species in water samples; the published document is brief (7 pages) and has been withdrawn by ASTM.

Abstract

ASTM D2334-88e1 provided standardized laboratory procedures for determining radioactive iodine in aqueous matrices (historically including precipitation and distillation based approaches). The committee document was issued with a 1988 designation but was withdrawn in 1990; modern low‑level radioiodine analysis in water is now covered by later ASTM methods (for example D4785 series).

Scope

Scope (summary): procedures for the laboratory determination of radioactive iodine in water. Historically the D2334 family included distillation and precipitation approaches for isolating iodine from aqueous samples and preparing the separated iodine for radiometric measurement. The withdrawn D2334 methods were part of older radiochemical technique collections; contemporary low‑level radioiodine analysis in water is now specified in later ASTM test methods (e.g., D4785 series) which describe chemical separation (ion exchange/solvent extraction) and gamma counting for a range of radioiodine isotopes.

Key topics and requirements

• Chemical isolation of iodine species from water (distillation and/or chemical precipitation historically used).
• Use of carrier/chemical reagents to promote quantitative recovery of iodine.
• Conversion and purification steps to prepare isolated iodine for radiometric counting (precipitation as an insoluble iodide/iodine form for measurement).
• Sample handling and laboratory safety considerations for work with radioactive isotopes and chemical oxidants/reductants.
• Quality control: recovery checks, blanks and instrument/counting calibration to establish detection limits and accuracy.

Typical use and users

Users: laboratory analysts in environmental, public‑health and nuclear/radiochemistry laboratories; regulators and environmental consultants reviewing historical data; organizations conducting radiological monitoring of drinking water, groundwater or effluent streams. Typical use: method selection for monitoring radioactive iodine species in environmental or drinking water, historical reference for older analytical programs, and context when comparing legacy data to results produced by current ASTM or EPA methods.

Related standards

Relevant and later standards that address low‑level analysis of radioiodine in water include the ASTM D4785 series (Standard Test Method for Low‑Level Analysis of Iodine Radioisotopes in Water, current edition D4785‑20 and earlier revisions) and relevant EPA radiochemical procedures and guidance for radionuclide analysis. Users should use D2334 only as a historical reference and rely on current ASTM and regulatory methods for routine compliance or monitoring.

FAQ

Q: What is this standard?

A: ASTM D2334‑88E01 is an ASTM test‑method designation titled "Test Methods for Radioactive Iodine in Water" (1988 designation). It is a short committee procedure originally describing laboratory approaches to isolate and measure radioactive iodine in aqueous samples.

Q: What does it cover?

A: It covered laboratory separation and measurement techniques for radioactive iodine in water (historically including distillation and precipitation approaches). It served as a procedural reference for radiochemical analysis of iodine in environmental and drinking water samples. For current practice, modern ASTM methods (for example D4785) provide updated procedures and performance details.

Q: Who typically uses it?

A: Radiochemistry laboratories, environmental testing labs, regulators and consultants involved with radionuclide monitoring historically used D2334. Today these users generally apply the newer ASTM D4785 series or EPA‑approved radiochemical methods for operational monitoring and compliance.

Q: Is it current or superseded?

A: ASTM D2334‑88E01 has been withdrawn (ASTM records indicate withdrawal in 1990). Contemporary, active ASTM procedures for low‑level radioiodine in water are published under the D4785 series (latest edition 2020). D2334 should be treated as a historical document and not as the current standard for routine testing.

Q: Is it part of a series?

A: D2334 was part of historic ASTM radiochemical method collections for water analysis. It is not an active series; later work on radioiodine methods continued under other ASTM designations (notably D4785 and its revisions).

Q: What are the key keywords?

A: Radioactive iodine, radioiodine, iodine‑131, water analysis, radiochemistry, precipitation, distillation, low‑level detection, ASTM.
