1.1 This test method covers the measurement of soluble, suspended, and total 226Ra in water in concentrations above 3.7 × 10−3 Bq/L. This test method is not applicable to the measurement of other radium isotopes.
1.2 This test method may be used for quantitative measurements by calibrating with a 226Ra standard, or for relative measurements by comparing the measurements made with each other.
1.3 This test method does not meet the current requirements of Practice .
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 Hydrofluoric acid (HF) is very hazardous and should be used in a well-ventilated hood. Wear rubber gloves, safety glasses or goggles, and a laboratory coat. Avoid breathing any HF fumes. Clean up all spills promptly and wash thoroughly after using HF.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
