Prospects for the Development of an 225Ac/213Bi Generator Using Inorganic Hydroxide Sorbents

Аннотация

The ability of inorganic hydroxide sorbents Termoxid-5 (T-5) and Termoxid-39 (T-39) heat-treated at temperatures from 100 to 950°C to take up radionuclides of the ²²⁵Ac subfamily was examined in a wide range of solution acidities and salt compositions. T-5 and T-39 are principally suitable for the development of both direct and inverse ²²⁵Ac/²¹³Bi generators with the activity of hundreds of millicuries of ²²⁵Ac.
