Determination of the specific surface of radioactive catalysts

A new variation of an adsorption vacuum setup for determining the specific surface of radioactive solids by the BET method using krypton was proposed.
The surfaces of radioactive and nonradioactive magnesium-sodium sulfate catalysts for alcohol dehydration were determined, and it was shown that when the isotope S35 is introduced, the specific surface of the radioactive samples practically does not differ from the surface of nonradioactive samples of the same composition.
External bombardment of the sulfate catalyst by fast neutrons, as well as by the neutrons of the nuclear reactor, leads to a certain increase in the specific surface.
