SODIUM ACTIVATION BY FAST NEUTRONS IN MAN PHANTOMS
Journal Article
·
· Physics in Medicine and Biology (England)
Measurements were made of the activation, by fast neutron irradiations, of a dilute aqueous solution of sodium nitrate contained in man phantoms. Phantom shapes included a cylinder 30 cm in diameter, a slab 30 cm thick and an approximately man-shaped phantom. Monoenergetic neutrons were used, at energies of 0.2, 0.5, 2.5, and 6.2 Mev. From the measurements the neutron capture probability in a man may be determined for use in dose assessment after a criticality accident. A representative value of about 0.4 was obtained. The results for neutron capture, derived from sodium activation for both cylinder and slab, were compared with other values. (auth)
