Solid state RCA Radio - uranium

We found this on sale at an antique mall for $15. It is pretty spicy! I quickly googled it, and from what I can find is this was made between the 60s and 70s. I’m kinda surprised that uranium was still used then. Any info?

A few radium clocks that I just got. One definitely spicier than the other.

The one in the left not much higher than background (0.02 mR/h). I these two in one shipment. The hot one on the left made up for it.

Perhaps my oldest radium piece to date!

My radioactive vacuum tube uses radium lume.

I recently picked up this radioactive vacuum tube, I couldn't find what isotope it used online but I deduced it wasn't a gas since it's more radioactive at one end than the other. Today I was shining my UV light on it, for some reason, and I noticed some fluorescent dust at the bottom, upon closer inspection it turns out there's just a blob of radium lume on the cathode.

Just got my 102 and I’m freaking out a bit.

I just got my radiacode 102 and was checking stuff around my room. I noticed an old ww2 era radio I have, a BC-603. It appears like the buttons have radium as my radiacode picked up around 54 usv/h maximum. It was heavily dependent on what angle I held it at. The levels quickly fell off only a few inches away. Does anybody know if there is a high risk here if so, what I should do? I’ve had this radio for years but l really don’t have an attachment to it now I want to get rid of it. Is there any other setting or way I can use the radiacode to better assess the risk here?

Big Ben futurua.

New one came in the mail today! Big ben futurua, made 1973-78, from what I can find only the big ben version is radium. Which further backs westclox stopping radium use in 1975, seeing the baby ben version was made in 1976-81.

Been a while.

It's been a while since I updated the collection, as for radon yes it's well within safe numbers. Still can't believe it was only going to be 16 clocks in total I would collect.

Found one with "radium" written on it

I have been looking around for something like this for a good while now. May consider putting this on the bug sell swap thread, but I found it for less than 9 bucks, it seems to be a decently rare piece as I only saw 2 other ones and both were bought long ago, and the piece is from the 30's allegedly

To find something like this is actually decently rare, at least in my area and the shops I've been hitting. In my experience with about 9 antique shops over 2 years this is the only one I have seen. The dangers if radium are widely known now, which is another reason I'm surprised someone would just be willing to sell it off for so cheap.

Newest find.

Baby Ben Style 8 Repeater from 1971-1975. I confirmed it was radium but before I could grab a picture of the reading my Geiger counter died. Gotta find that new battery that’s around here some where.
