DETERMINATION OF BERYLLIUM BY THE PHOTONEUTRON METHOD
Apparatus was designed and constructcd for the determination of beryllium by the photoneutron method, which can be employed in any analytical laboratory without hazard or difficulty. Because large B/sup 10/F/sub 3/ neutron counter tubes are used, the neutron detection efficiency of the instrument is sufficientiy great so that a gamma source activity of only approximates 300 millicuries of Sb/sup 124/ is necessary for most samples. With this source activity sample solutions containing as little as 60 mu g of Be per ml, or 1.5 mg total beryllium, can be analyzed with a relative standard deviation of 1%. Interference caused by elements which absorb neutrons can be eliminated by the cadmium shield technique. Deuterium is an interference if present in a 25-fold excess over beryllium. Results are shown for the determination of beryllium in several types of materials. (auth)
