How does an object become radioactive just by being near or touching something else that is radioactive?
In: Physics
Imagine keeping a soccer ball up the air by continuously kicking it. You can’t relax while you have the ball it takes a lot of concentration. You and the ball are “unstable”. Now you kick it off to the person next to you so you can sit down and relax but now that person is juggling the ball and is unstable. Eventually they too will need to kick the ball away.
