BL-5鈾礦石成分分析標(biāo)準(zhǔn)物質(zhì)Uranium OreU：7.09 %
Certified Reference Material: Uranium Ore
Consensus Value 95% Confidence Interval

Ra-226 857 Bq/g ± 38 Bq/g
Pb-210 866 Bq/g ± 21 Bq/g
Description
BL-5 is a low-grade concentrate from Beaverlodge, Saskatchewan. The major mineralogical components are, in decreasing order of abundance: plagioclase feldspars, hematite, quartz, calcite and dolomite, chlorite and muscovite; uraninite is the main uranium-bearing mineral. The concentrate was dried at 100°C, dry-ground to minus 74 μm, blended, sampled systematically for analysis by X-ray fluorescence and chemical methods to demonstrate homogeneity sufficient for use as a compositional reference material for uranium and bottled in 100-g units. Evidence is available that BL-5 is in secular equilibrium.
Certification
The consensus value for uranium is the unweighted mean of 337 accepted analytical determinations by 24 laboratories. Methods included titrimetry, colorimetry, fluorimetry, x-ray fluorescence, neutron activation analysis, radiochemistry and isotope dilution.
Legal notice
The Canadian Certified Reference Materials Project has prepared this reference material and statistically evaluated the analytical data of the inter-laboratory certification program to the best of its ability. The Purchaser by receipt hereof releases and indemnifies the Canadian Certified Reference Materials Project from and against all liability and costs arising out of the use of this material and information.
