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.
NanocurienCi
Target UnitA nanocurie (nCi) is a non-SI unit of radioactivity that represents one billionth (10^-9) of a curie. The curie, named after Marie and Pierre Curie, was originally defined based on the radioactivity of one gram of radium-226. The nanocurie is often used in fields such as nuclear medicine, radiation safety, and environmental monitoring to quantify low levels of radioactivity. It allows for precise measurements in contexts where radioactive materials are present in minute amounts, making it crucial for safety and regulatory purposes.
Current Use
Today, the nanocurie is widely used in various fields such as nuclear medicine, where it is essential for dosing radioactive tracers in diagnostic imaging or therapy. It is also utilized in environmental monitoring to assess background radiation levels and contamination. Regulatory agencies employ the nanocurie to set safety standards and guidelines regarding exposure to radioactive materials, ensuring public health and safety. Laboratories often measure samples in nanocuries to determine the amount of radioactivity present in environmental samples and medical preparations.
Fun Fact
The curie was originally based on the radioactivity of radium, one of the first radioactive elements discovered.

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.

Nanocurie
radiation • Non-SI
Definition
A nanocurie (nCi) is a non-SI unit of radioactivity that represents one billionth (10^-9) of a curie. The curie, named after Marie and Pierre Curie, was originally defined based on the radioactivity of one gram of radium-226. The nanocurie is often used in fields such as nuclear medicine, radiation safety, and environmental monitoring to quantify low levels of radioactivity. It allows for precise measurements in contexts where radioactive materials are present in minute amounts, making it crucial for safety and regulatory purposes.
History & Origin
The curie was established in 1910, based on the radioactivity of radium, and it was named in honor of the Curies for their pioneering work in radioactivity. The nanocurie was subsequently derived from the curie to facilitate the measurement of much smaller quantities of radioactive material, recognizing the need for precision in scientific and medical applications. The adoption of the nanocurie in scientific literature allows researchers and practitioners to discuss radioactivity at scales relevant to their studies and applications.
Etymology: The term 'nanocurie' is a combination of the prefix 'nano-', which denotes one billionth (10^-9), and 'curie', named after Marie Curie, the renowned physicist and chemist.
Current Use
Today, the nanocurie is widely used in various fields such as nuclear medicine, where it is essential for dosing radioactive tracers in diagnostic imaging or therapy. It is also utilized in environmental monitoring to assess background radiation levels and contamination. Regulatory agencies employ the nanocurie to set safety standards and guidelines regarding exposure to radioactive materials, ensuring public health and safety. Laboratories often measure samples in nanocuries to determine the amount of radioactivity present in environmental samples and medical preparations.
💡 Fun Facts
- •The curie was originally based on the radioactivity of radium, one of the first radioactive elements discovered.
- •1 curie is equivalent to approximately 37 billion disintegrations per second.
- •The nanocurie is particularly relevant in fields like radiopharmaceuticals, where precise dosing is crucial.
