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.
MillicuriemCi
Target UnitThe millicurie (mCi) is a non-SI unit of radioactivity that quantifies the amount of radioactive material present. One millicurie is equal to 3.7 × 10^7 disintegrations per second, which is derived from its relationship to the curie. The curie, named after Marie and Pierre Curie, was established as a unit to represent the amount of radioactive material that produces 37 billion disintegrations per second. Thus, a millicurie represents a smaller quantity, suitable for medical and scientific applications where precise radioactivity levels are crucial.
Current Use
The millicurie is predominantly used in the fields of nuclear medicine and radiopharmaceuticals. It allows for the easy measurement of small amounts of radioactive isotopes used in diagnostic imaging and treatments for conditions such as cancer. Its use extends to research laboratories, where precise measurements of radioactivity are essential for experiments involving radioactive materials. Regulatory agencies often require the activity of radioactive substances to be expressed in millicuries for safety and compliance purposes.
Fun Fact
The curie is named after Marie Curie, the first woman to win a Nobel Prize.

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.
💡 Fun Facts

Millicurie
radiation • Non-SI
Definition
The millicurie (mCi) is a non-SI unit of radioactivity that quantifies the amount of radioactive material present. One millicurie is equal to 3.7 × 10^7 disintegrations per second, which is derived from its relationship to the curie. The curie, named after Marie and Pierre Curie, was established as a unit to represent the amount of radioactive material that produces 37 billion disintegrations per second. Thus, a millicurie represents a smaller quantity, suitable for medical and scientific applications where precise radioactivity levels are crucial.
History & Origin
The curie was established in the early 20th century during pioneering research on radioactivity led by Marie and Pierre Curie. The unit was named in their honor, recognizing their significant contributions to the field. The millicurie was subsequently defined as a fraction of the curie, facilitating the use of smaller quantities of radioactive substances in practical applications. This subdivision became essential for medical diagnostics and treatment, allowing for more manageable dosages in therapeutic contexts.
Etymology: The term 'millicurie' combines the prefix 'milli-' from Latin, meaning one-thousandth, with 'curie,' named after the Curies who discovered radium and polonium.
Current Use
The millicurie is predominantly used in the fields of nuclear medicine and radiopharmaceuticals. It allows for the easy measurement of small amounts of radioactive isotopes used in diagnostic imaging and treatments for conditions such as cancer. Its use extends to research laboratories, where precise measurements of radioactivity are essential for experiments involving radioactive materials. Regulatory agencies often require the activity of radioactive substances to be expressed in millicuries for safety and compliance purposes.
💡 Fun Facts
- •The curie is named after Marie Curie, the first woman to win a Nobel Prize.
- •1 millicurie is roughly equivalent to the radioactivity of about 10 micrograms of radium-226.
- •The millicurie is often used in conjunction with the SI unit becquerel, where 1 mCi equals 37 million Bq.
