One reason radiation is dangerous is that it can’t be detected with the senses. You normally can’t see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation.
Context: Andre is interested in radiation and decides to buy a Geiger counter. He takes his new Geiger counter near the power plant in his town and it starts clicking as he gets closer. As he leaves the area around the power plant and goes home the Geiger counter clicks slower and slower until it almost stops completely.
Question: Which area has more radiation, the power plant or Andre's home?
