[Rockhounds] info on radioactive minerals

[larryrush at att.net]

I recently picked up a flat of minerals labeled "radioactive". Normally, I
don't bother much with these, but working with the torbernite has been an
interesting experience, so I can use some help here with these...

 

Of the 16 hand sized pieces in the flat, 7 are labeled Uraninite, Canadian
Dyno mine, Cardiff, Ontario, and 9 are labeled Allanite and Cyrtolite
(Zircon), McDonald Mine, Hybla, Ontario (ghost town).

There are no crystals or faces showing, just masses and clusters of grains.
The matrix in each of these appears to be a feldspar.

 

I have no idea of the "hotness" of them, or of their worth as specimens, but
I'd appreciate any information on them, or similar pieces.

(If interested in buying any, make me an offer.)
