to ine the cilinder use water because that is what stops radioactivity. they use it in nuclear power plants to cooldown and keep the radioactivity lvls down to a suprisingly almost nothing and before it was enough to kill you ifyou stood next to it.(hope this helps;).)
Interesting... I suppose the best way to find out would be to experiment. However, I have some issues with your reasoning; First, The water used in nuclear reactors is not ordinary water, it is heavy water containing deuterium, this heavy water acts as a moderator, not a shield to slow down neutrons for fission. The real shielding comes from the very thick concrete walls around the reactor. And finally, the radiation in a reactor is mostly neutron radiation, I'm trying to shield gamma.
well i watched a video on youtube were they were in a nuclear power plant the person was in the room with SPENT fuel rods from the reactor the way I under stood it is that they used water or heavy water to sheild i will go back and check if you are right or if im right and will tell you who put the video on and you can see and can tell me if im wrong.(sorry i looked over my comment and say that some one could take it offensive and i didnt mean it for it to be that way sorry).
@amethyst8teen Some good 'fyi' - generally speaking water is a good radiation 'shield' across the board. Heavy water can be used but is less effective than very pure 'normal' or 'light' water because the nuclei of heavy water hydrogen atoms are less likely to absorb the radiating neutrons (because they already have extra neutrons in their nuclei). Being good for slowing down the neutrons/decreasing the number of neutrons is essentially one and the same as 'shielding' against them.
@amethyst8teen The reason one might use heavy water to moderate a reactor is to produce plutonium and/or tritium. A few millimeters even of aluminum can be used to stop most beta particles, though you might consider positioning the material in the middle of a box several times bigger than the clock for distance as alpha particles don't travel far because they are relatively massive, which is also what makes the so damaging.
@amethyst8teen For gamma rays....lol, now the ironic part. Since you mentioned you don't want to use lead as a shielding material, uranium works great! Depleted uranium is roughly 5 times better at shielding against gamma rays than lead! Though, if you're prejudiced against lead, safe to assume you're not a big fan of depleted uranium either.... depending on the intensity, thick aluminum could work, sand, concrete...the denser the material the better.
@amethyst8teen Also, some more radium fun.... Radium only produces alpha particles. While radium doesn't actually produce beta particles or gamma rays, the decay byproducts of the radium do. Radium is also almost 1 million times more radioactive than an equal mass of uranium 235. Radium was discovered by the Curies, and their lab books are too "radioactive" to be handled. Also, clocks are used for keeping track of time.... :)
That being said, thank you for the advice, you've inspired me to do some experiments and possibly make a video out of it. Oh and regular water is used to cool the reactor but plays a very small part in shielding it.
Awesome! I'm keeping the parts of the disassembled clock stored in plastic bags at the moment housed in a 1/4" steel box, not that that shields the gamma rays even a little. I'm thinking I'll make a storage system consisting of a small metal canister housed in a larger canister filled with sand, hopefully about 4-6 inches of a dense sand on all sides will cut down the rays... Or maybe iron filings, Can you think of a suitable material? No lead though...
This is true, but if you dig around some second hand stores you might find something, I just took apart one of two radium clocks I found at a thrift shopped for $4 apiece.
Yeah, I'm not worried about it, I keep it and two other radium clocks on my dresser in my room with a bunch of other radioactive things. Your right of course it would only be dangerous in a flake of radium came off and I inhaled or ingested it. But I've checked it before and I'd notice if any radium was missing. And your english is better than some of my classmates :)
Thanks! so do I!

Nice clock :) I like it.

That's a nice clock, really art-deco looking. Don't sleep with it under your pillow.

is that radium glass as well? that's a really nice clock btw!

I didn't find it offensive, so don't worry. But I'm pretty sure they use heavy water, which is expensive and difficult to come by.

what would be sweet if it was uranium glass for the body of the clock

Yeah, I'm not worried about it, its only dangerous if it is emitted inside you.

well, it's dangerous, but it's too little radiation
but i think that's a not necessary risk ;D
nice, nice !
