Alpha-particle track autoradiographic study of the distribution of a [211At]-astatinated drug in normal tissues of the mouse.

ABSTRACT

The microscopic distribution of the potential endoradiotherapeutic drug, 6-[211At]-astato-2-methyl-1,4- naphthoquinol bis (diphosphate salt) in normal tissues of the mouse has been studied by alpha-particle track autoradiography. The uptake into critical radiosensitive tissues, especially bone marrow, colon and lung, was low.
