Historical Standard: ASTM D4785-08 Standard Test Method for Low-Level Analysis of Iodine Radioisotopes in Water
SUPERSEDED (see Active link, below)
ASTM D4785
1. Scope
1.1 This test method covers the quantification of low levels of radioactive iodine in water by means of chemical separation and counting with a high-resolution gamma ray detector. Iodine is chemically separated from a 4-L water sample using ion exchange and solvent extraction and is then precipitated as cuprous iodide for counting.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information purposes only.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Note 2 , Note 3, Note 9, and Section 9 .
