title: [Absorption from the gastrointestinal tract of rats of biologically incorporated 241Am found in fish].
abstract: In experiments on mongrel albino rats it was shown that the absorption of 241Am "biologically incorporated" in fish from the gastrointestinal tract amounted to 0.1% and exceeded by 4.5 times the intake of 241Am nitrate and by 6 times the absorption of 241Am administered in fish externally contaminated with americium 241.
