Neutron Activation Analysis with van de Graaff Accelerator

The determination of chlorine, bromide and iodine in biological material by activation analysis

“…Neutron-activation analysis has been applied to the halogens in a number of cases (e.g. Brues & Robertson, 1950;Atchison & Beamer, 1956;Cosgrove, Bastian & Morrison, 1958; for bibliography see Gibbons, Loveridge & Millett, 1957). It appears to be quite as sensitive and accurate as conventional methods for chlorine (cf.…”

Accelerator Systems for Activation Analysis—A Comparative Survey

“…The first major applications of accelerators as neutron sources for activation analysis were based on the Van de Graaff [1][2][3]. Much of the early developmental work using these accelerators was done by Atchison and Beamer at the Dow Chemical Company [3].…”

“…Much of the early developmental work using these accelerators was done by Atchison and Beamer at the Dow Chemical Company [3]. The distinguishing feature of a Van de Graaff accelerator is the continuous transfer of electric charge from a low-voltage dc power supply to a hemispherical high-voltage terminal by means of a rapidly moving insulated belt.…”

Determination of Iodine, Bromine, and Chlorine in Atmospheric Samples by Neutron Activation Analysis

“…Shake funnel (1) for 60 seconds (I -is oxidized to I 2 and extracted into the CC1 4 layer) and add the CC1 4 to funnel (2) and the aqueous layer to funnel (3). Shake funnel (3) for 30 seconds to give the aqueous layer a second CC1 4 wash and remove the last traces of I 2 , and then add the CC1 4 layer to funnel (2). Save the aqueous layer of funnel (3) for bromine.…”
