Question: What objects are radioactive

Sarah Hunak answered on 14 Nov 2016:

everything! Everything around is us slightly radioactive, even if only a tiny amount. Bricks, the ground, food, even us! But like I said, only in very small amounts so it’s not harmful. Things like bananas and brazil nuts take up radioactive minerals from the soil and so when we eat them they can be a bit radioactive , but don’t let that put you off eating bananas!
