Question

) A company built five identical houses in different parts of the same country. When a radioactivity count was carried out in each house, one of them had a much higher reading than the others.
What is most likely to cause this higher reading?

Answer 1

Radiation plays a key role in modern life, be it the use of nuclear medicine, space exploration or electricity generation. Radiation constantly surrounds us as a result of naturally occurring radioactive elements in e.g. the soil, the air and the human body. As a result of many decades of research, the health impacts of radiation are very well-understood
