This standard applies to 5L geological water samples 234U/238U, 230Th/232Th ratio of radioactivity measured. For 5L environmental water samples The 234U/238U, 230Th/232Th radioactivity can be measured with reference to the ratio of use. Measuring range. Uranium. greater than 1.23 × 10-3Bq/L; Th. greater than 1.23 × 10-3Bq/L; 230Th/232Th. not more than 15.2 Normative referencesThe following documents contain provisions which, through this standard reference and become the standard terms. For dated references, all subsequent Revision < not including the contents of errata> or revisions do not apply to this standard, however, encourage the parties to study under this agreement is standard Whether the latest versions of these documents.

GB/T 6379 (all parts) of measurement methods and results Accuracy (trueness and precision) GB 9133 Classification of radioactive waste GB 14500 radioactive waste management 3 P350 Levextrel extraction chromatography α spectroscopy 3.1 Principle A certain volume of water samples, after adding acidified with nitric acid. Carrier added ferric chloride and ammonium chloride, pH was adjusted with ammonia, uranium, thorium and enriched with hydrogen Oxide form precipitation. The precipitate was dissolved with concentrated nitric acid to prepare a solution to the column, through the P350 extraction chromatographic column, separated from other interfering elements, Purification of uranium and thorium. With hydrochloric acid elution thorium, uranium and then eluted with sodium fluoride. Electrodeposition process for producing thorium and uranium α source. Respectively α spectrometer The measurement of uranium and thorium isotopes α spectrum curve, and calculated the ratio. 3.2 Reagents Unless otherwise stated in this section, both in the analysis using analytical grade and distilled water or equivalent purity water in line with national standards. 3.2.1 ammonium oxalate. 3.2.2 ammonium chloride. 3.2.3 of aluminum nitrate [Al (NO3) 3 · 9H2O]. 3.2.4 tartaric acid. 3.2.5 ammonia (ρ0.91g/mL). 3.2.6 nitrate (ρ1.42g/mL). 3.2.7 hydrofluoric acid. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13071-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 13071-2010_English as soon as possible, and keep you informed of the progress.
