What is the Difference Between Becquerel and Sievert?

The main difference between Becquerel and Sievert lies in what they measure and their application in the context of radiation.

• Becquerel (Bq): This unit indicates the amount of radioactivity, focusing on where radiation comes from. It is used to express the amount of radioactive materials contained in soil, foods, tap water, etc. The higher the value expressed in becquerels, the larger the radiation being emitted. Becquerel measures the rate of radioactive decay.
• Sievert (Sv): This unit measures the radiation exposure dose that a person receives, and it is used with regard to the human body. The larger the value expressed in sieverts, the larger the effects of radiation to which the human body is exposed. Sievert measures the absorbed dose of radiation in living organisms.

In summary, Becquerel is a unit for measuring radioactivity and the rate of radioactive decay, while Sievert is a unit for measuring the radiation exposure dose that a person receives and its effects on the human body.
