This standard compared with GB/T 13072-1991, the main changes are as follows. --- A standard specification title; --- Increased alert, warnings; --- Provision increases the processing of waste; --- Deleted directory; --- Simplifies the measuring instruments; --- Corrected some errors. The standard proposed by the People's Republic of China Ministry of Land Resources. This standard by the National Standardization Technical Committee of Land and Resources. This standard is drafted by. National Geological Experimental Test Center. This standard was drafted. Nuclear Industry Beijing Institute of Geology. The main drafters of this standard. Wu Zhaohui, Li-kun. This standard replaces the standards previously issued as follows. --- GB/T 13072-1991. Geological water samples 226Ra/228Ra radioactivity Ratio determination emanation method -β law Warning --- personnel should use this standard practice regular laboratory work. This standard does not point out all possible security asked question. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.1 ScopeThis standard specifies the method for the analysis of geological water samples 226Ra/228Ra ratio of radioactivity, which, 226Ra measured by emanation, 228Ra 228Ac measured on a low background β by means of its daughter. This standard applies to surface water, groundwater, uranium and uranium mine water plant Wastewater 226Ra/228Ra radioactivity ratio analysis, environmental Sewage, water and solid samples after appropriate treatment can also refer to use. Measuring range. 226Ra specific activity > 3.6 × 10-3Bq/L and 228Ra specific activity > 3.5 × 10-3Bq/L or more of a variety of ratios.2 Normative referencesThe following documents contain provisions which, through this standard reference and become the standard terms. For dated references, all subsequent Modified version (not including errata content) 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. For undated reference documents, the latest versions apply to this standard. 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 Principle 3 5L acidified water samples with lead sulfate, barium, radium co-precipitation and dissolved with disodium edetate (EDTA disodium), filtered to Insoluble debris re-use sulfate precipitate was dissolved with diethyl be sub-pentaacetic acid (DTPA, C14H23N3O10) after 228Ac grow again As sulfate precipitation, the precursor 226Ra and 228Ac separate solution of the ester (P204, C16H35O4P) and extracted with di (2-ethylhexyl), anti-nitrate Extraction, cerium oxalate precipitate source system, measuring 228Ac, and the standard comparison solution at low background β means, including the degree of 228Ac get, and then converted into 228Ra activity. Sulfate precipitate was dissolved with disodium edetate charged diffuser. It closed a few days later by emanation and measurement 226Ra Comparison of standard solutions obtained radium 226Ra activity, the final calculation of 226Ra and 228Ra radioactivity ratio.4 ReagentsUnless otherwise stated in this section, both in the analysis using analytical grade and distilled water or equivalent purity water in line with national standards. 4.1 mannitol. 4.2 absolute ethanol (ρ0.78g/mL). 4.3 hydrochloride (ρ1.19g/mL). 4.4 hydrochloric acid solution (12). 4.5 nitric acid solution (114). 4.6 sulfuric acid solution (11). 4.7 Sodium hydroxide solution (100g/L). 100g of sodium hydroxide dissolved in water, diluted to 1000mL. 4.8 ammonia solution (12). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13072-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 13072-2010_English as soon as possible, and keep you informed of the progress.
