Yes, Carnotite is radioactive.
Yes, you are right. It's carnotite and uraninite.
the main element extracted was radium
There aren't any "deposits" of radium compounds, but there are traces of it in a lot places where traces (or more) of uranium are found. The tiny bit of this element that occurs naturally is widely distributed. With a great deal of effort, it can be accumulated from the refining of carnotite, an ore of uranium. Radium is (highly) radioactive, and it is a daughter of the radioactive decay of thorium, which is, in turn, a radioactive daughter of uranium decay. The uranium and thorium in this decay chain are long lived, and radium is relatively short-lived. This translates into the idea that only trace amounts of it exist naturally. The chemistry of radium was known largely from working with only trace amounts. Additional information was gleaned from the study of larger quantities following its separation from carnotite, a uranium ore. A link to the Wikipedia article on radium is provided.
Uranium minerals as pitchblende, uraninite, carnotite, autunite, davidite, etc. or as a secondary product from the mining of gold, vanadium, phosphates.
pitchblende and carnotite; also as residual material in the industry of phosphate fertilizers, from the mining of gold, vanadium, copper, etc.

Uranium
Minerals like uraninite and carnotite are highly radioactive ores of uranium.

The formula K2(UO2) 2 (VO4) 2 is the formula of the important uranium mineral carnotite. Percent uranium (not moles) in carnotite: 52,77 %.
