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.
MicrocurieµCi
Target UnitThe microcurie is a unit of radioactivity in the field of nuclear science and radiation measurement. It is defined as one millionth (10^-6) of a curie (Ci), a unit originally established based on the radioactivity of radium-226. The curie is based on the decay rate of 1 gram of radium-226, which produces approximately 37 billion disintegrations per second. Thus, a microcurie represents 37,000 disintegrations per second. This unit is crucial for measuring low levels of radioactivity, particularly in medical applications, environmental monitoring, and scientific research.
Current Use
Today, the microcurie is commonly used in the medical field, particularly in nuclear medicine for diagnostic imaging and therapies. It allows healthcare professionals to quantify the radioactivity of substances used in procedures like PET scans and for tracking radioisotopes in the body. Additionally, it is utilized in research laboratories and environmental monitoring to measure low levels of radiation in various materials.
Fun Fact
The microcurie is often used to measure radioactivity in food, ensuring safety in consumption.

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.

Microcurie
radiation • Non-SI
Definition
The microcurie is a unit of radioactivity in the field of nuclear science and radiation measurement. It is defined as one millionth (10^-6) of a curie (Ci), a unit originally established based on the radioactivity of radium-226. The curie is based on the decay rate of 1 gram of radium-226, which produces approximately 37 billion disintegrations per second. Thus, a microcurie represents 37,000 disintegrations per second. This unit is crucial for measuring low levels of radioactivity, particularly in medical applications, environmental monitoring, and scientific research.
History & Origin
The term 'curie' was named in honor of the pioneering physicists Marie and Pierre Curie, who conducted groundbreaking research on radioactivity in the late 19th and early 20th centuries. The microcurie was adopted as a subunit to allow for more manageable measurements of radioactivity, particularly in fields where low levels of radioactivity are encountered, such as medicine and environmental science.
Etymology: The word 'curie' derives from the last name of Marie Curie, who, along with her husband Pierre, was instrumental in the discovery of radium and polonium.
Current Use
Today, the microcurie is commonly used in the medical field, particularly in nuclear medicine for diagnostic imaging and therapies. It allows healthcare professionals to quantify the radioactivity of substances used in procedures like PET scans and for tracking radioisotopes in the body. Additionally, it is utilized in research laboratories and environmental monitoring to measure low levels of radiation in various materials.
💡 Fun Facts
