Unit Explanations
BecquerelBq
Source UnitThe becquerel (Bq) is the SI unit of radioactivity, representing the activity of a quantity of radioactive material in which one nucleus decays per second. This unit is named after Henri Becquerel, who discovered radioactivity in 1896. The concept of radioactivity encompasses processes such as alpha decay, beta decay, and gamma decay, which involve the transformation of unstable atomic nuclei. As a measure of disintegrations, the becquerel provides a quantifiable means to gauge the intensity of radioactivity in various materials, essential for safety in medical, industrial, and research applications.
Current Use
The becquerel is widely used in medical applications, such as in nuclear medicine for dosimetry and assessing the radioactivity of radiopharmaceuticals. It is also employed in environmental studies to monitor radioactive contamination and assess safety in nuclear power facilities. Regulatory bodies and safety guidelines use becquerels to ensure public health and safety regarding exposure to radioactive materials.
Fun Fact
The becquerel was officially adopted as an SI unit in 1975, a testament to the growing importance of radioactivity in science and safety.
CurieCi
Target UnitThe curie (symbol: Ci) is a non-SI unit of radioactivity that quantifies the activity of a radioactive substance. It is defined as the amount of radioactive material that produces 3.7 × 10^10 disintegrations per second, equivalent to the radioactivity of 1 gram of radium-226. The curie is named in honor of Marie Curie and her husband Pierre Curie, who conducted pioneering research on radioactivity. This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials. Despite the adoption of the SI unit becquerel, the curie remains popular in the United States and in various medical and industrial applications.
Fun Fact
The curie was originally based on the activity of radium, which was discovered by the Curies in 1898.

radiation • SI Unit
Definition
The becquerel (Bq) is the SI unit of radioactivity, representing the activity of a quantity of radioactive material in which one nucleus decays per second. This unit is named after Henri Becquerel, who discovered radioactivity in 1896. The concept of radioactivity encompasses processes such as alpha decay, beta decay, and gamma decay, which involve the transformation of unstable atomic nuclei. As a measure of disintegrations, the becquerel provides a quantifiable means to gauge the intensity of radioactivity in various materials, essential for safety in medical, industrial, and research applications.
History & Origin
The becquerel was introduced as a unit of measure in 1975 during the 14th General Conference on Weights and Measures (CGPM) in response to the growing need for standardized measurement of radioactivity. Prior to this, radioactivity was often measured in curies, a unit based on the activity of radium-226. The adoption of the becquerel provided a more universally applicable metric that aligned with the International System of Units (SI).
Etymology: The name 'becquerel' honors the French physicist Henri Becquerel, who discovered radioactivity in 1896, which led to significant advancements in nuclear physics and medicine.
Current Use
The becquerel is widely used in medical applications, such as in nuclear medicine for dosimetry and assessing the radioactivity of radiopharmaceuticals. It is also employed in environmental studies to monitor radioactive contamination and assess safety in nuclear power facilities. Regulatory bodies and safety guidelines use becquerels to ensure public health and safety regarding exposure to radioactive materials.
