Anything works to stop radiation but lead is effective, safe and easy to handle, and relatively inexpensive. Seriously, check cost of lead vs depleted uranium.
A cloud chamber is an instrument that detects radioactivity by condensing gases to create visible vapor trails from ionizing radiation particles. These trails make the presence of radioactivity visible and can help identify the type and energy of the particles.

You can lead a middle school chamber group using the Chamber Music Program.
Uranium becomes lead
Lead
To replace the lead in a Parker Jotter mechanical pencil, follow these steps: Unscrew the tip of the pencil to access the lead chamber. Remove any remaining lead fragments from the chamber. Insert a new lead refill into the chamber, ensuring it is securely in place. Screw the tip back on the pencil and test to make sure the lead advances properly.
The protective apron used by dentists contains lead, which is highly opaque to radioactivity. (You would also notice that if you read Superman comic books; lead is used to safely contain kryptonite.)
His name is Dez Fafara, used to be the lead singer for Coal Chamber.
Usually lead (Pb) because it is a cheap heavy metal.
Rutherford used a lead box to shield against background radiation, which could interfere with his experiments on radioactivity. Lead is a dense material that effectively absorbs radiation, providing a protective barrier for sensitive equipment and preventing external radiation from influencing the results of his experiments.
Radioactive elements always emit hazardous radiations.Lead metal absorbs these radiations .Hence we put any radioactive element in a lead chamber.
In the lead chamber process, sulphur dioxide is oxidized to sulphur trioxide using atmospheric oxygen in the presence of a vanadium oxide catalyst. The sulphur trioxide is then absorbed in water to form sulphuric acid. The lead chamber process gets its name from the large lead-lined chambers used in the process to contain the reaction.
