Q: The amount of radiation being emitted by a radioactive material is measured using the conventional unit ––––––.
  • A. Watt
  • B. Pascal
  • C. Ampere
  • D. Curie
Correct Answer: Option D - The amount of radiation being emitted by a radioactive material is measured in Curie. It is the traditional unit of radioactivity and shows the activity of 1g of pure radium and is equal to 3.7×10¹⁰ disintegration/second. Becquerel is also the SI unit of radioactivity and is defined as the amount of a radioactive substance showing one disintegration/second.
