Unit of Radioactivity - Curie
The Curie (Ci) is a unit of radioactivity named after the renowned physicist and chemist Marie Curie. It is used to quantify the rate of radioactive decay of a substance. Radioactivity is the emission of ionizing radiation from the nucleus of an unstable atom as it undergoes radioactive decay.
Explanation:
- The Curie is defined as the activity of a quantity of radioactive material in which one gram of radium-226 undergoes 3.7 x 10^10 disintegrations per second.
- It is a large unit of radioactivity, so smaller units like the becquerel (Bq) are more commonly used in modern scientific research.
- One Curie is equivalent to 3.7 x 10^10 becquerels.
Significance:
- The Curie is still used in some contexts, especially in discussions of historical experiments and measurements related to radioactivity.
- It serves as a reference point for understanding the intensity of radioactivity in certain substances.
In conclusion, the Curie is a unit of measurement for radioactivity and is named in honor of Marie Curie's contributions to the field of nuclear physics.
