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.
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.

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
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.

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
- •The microcurie is often used to measure radioactivity in food, ensuring safety in consumption.
- •In space exploration, microcuries are used to monitor radiation exposure for astronauts.
- •The microcurie is part of a larger system of units that includes the millicurie (mCi) and nanocurie (nCi), allowing for a wide range of measurements.
