Unit Explanations
GrayGy
Source UnitThe gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
Current Use
The gray is widely used in medical fields, particularly in radiation therapy for cancer treatment, where precise dosages are critical for effective treatment while minimizing damage to surrounding healthy tissue. It is also employed in radiological assessments, nuclear power, and safety protocols for radiation workers. Various international organizations, including the International Atomic Energy Agency (IAEA), utilize the gray for consistent communication regarding radiation exposure levels.
Fun Fact
The gray is equivalent to 100 rad, an older unit of absorbed dose.
MillibecquerelmBq
Target UnitThe millibecquerel (mBq) is a submultiple of the SI unit of radioactivity, the becquerel (Bq). It represents a radioactive decay rate of one thousandth of a decay event per second. In terms of definition, the becquerel is defined as one decay per second, thus one millibecquerel corresponds to 0.001 decays per second. This unit is particularly useful in fields such as nuclear medicine and environmental monitoring, where precise measurement of low levels of radioactivity is crucial. The millibecquerel allows scientists and health professionals to express small concentrations of radioactive materials in a more manageable form.
Current Use
Today, the millibecquerel is widely used in various sectors including nuclear medicine, radiological safety, and environmental monitoring. It allows for the measurement of very low levels of radioactivity, making it feasible to assess contamination levels in food, water, and biological samples. Regulatory bodies often set safety guidelines in terms of millibecquerels, ensuring public health is maintained concerning exposure to radioactive materials.
Fun Fact
One millibecquerel is equivalent to 0.001 decays per second, a minuscule amount emphasizing the need for precise detection methods.

radiation • SI Unit
Definition
The gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
History & Origin
The gray was introduced in 1975 by the International System of Units (SI) as the unit of absorbed dose to provide a standardized measurement for radiation exposure. Its creation was a response to the need for a unified system that could facilitate consistency in scientific research and practical applications in radiology, nuclear medicine, and radiation therapy.
Etymology: The unit is named after the British physicist Louis Harold Gray, who made significant contributions to the field of radiation therapy and the study of radiation's effects on biological tissue.
Current Use

Millibecquerel
radiation • Non-SI
Definition
The millibecquerel (mBq) is a submultiple of the SI unit of radioactivity, the becquerel (Bq). It represents a radioactive decay rate of one thousandth of a decay event per second. In terms of definition, the becquerel is defined as one decay per second, thus one millibecquerel corresponds to 0.001 decays per second. This unit is particularly useful in fields such as nuclear medicine and environmental monitoring, where precise measurement of low levels of radioactivity is crucial. The millibecquerel allows scientists and health professionals to express small concentrations of radioactive materials in a more manageable form.
History & Origin
The millibecquerel was established as a unit of measurement for radioactivity in the 20th century, following the introduction of the becquerel, which was named after the French physicist Henri Becquerel. Becquerel discovered radioactivity in 1896, which marked a significant milestone in nuclear physics. The need for smaller units emerged as scientific research progressed, particularly in fields requiring the quantification of minute radioactive emissions, leading to the adoption of the millibecquerel in various regulatory and scientific contexts.
Etymology: The term 'millibecquerel' derives from the name of Henri Becquerel, combined with the prefix 'milli-', which signifies one thousandth.
Current Use
Today, the millibecquerel is widely used in various sectors including nuclear medicine, radiological safety, and environmental monitoring. It allows for the measurement of very low levels of radioactivity, making it feasible to assess contamination levels in food, water, and biological samples. Regulatory bodies often set safety guidelines in terms of millibecquerels, ensuring public health is maintained concerning exposure to radioactive materials.
💡 Fun Facts
- •One millibecquerel is equivalent to 0.001 decays per second, a minuscule amount emphasizing the need for precise detection methods.
- •The becquerel unit, and by extension the millibecquerel, is named after Henri Becquerel, who shared the Nobel Prize in Physics in 1903.
- •The use of the millibecquerel in medical applications helps to minimize radiation exposure, making it critical for patient safety.
