Determination of the 226Ra concentration in a New Brunswick Laboratory standard pitchblende sample

Creators

Description

The 226Ra concentration determined by the radon emanation method in a sample of NBL Reference Material No. 6-A, pitchblende ore was 192.6 +- 1.3 ng 226Ra/g ore. The weight ratio of radium to natural uranium was (3.344 +- 0.06) x 10-7. This value is not significantly different from the value of 3.374 x 10-7 expected if the radium were in radioactive equilibrium with its 238U parent
