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.
CurieCi
Target UnitThe curie (symbol: Ci) is a non-SI unit of radioactivity that quantifies the activity of a radioactive substance. It is defined as the amount of radioactive material that produces 3.7 × 10^10 disintegrations per second, equivalent to the radioactivity of 1 gram of radium-226. The curie is named in honor of Marie Curie and her husband Pierre Curie, who conducted pioneering research on radioactivity. This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials. Despite the adoption of the SI unit becquerel, the curie remains popular in the United States and in various medical and industrial applications.
Fun Fact
The curie was originally based on the activity of radium, which was discovered by the Curies in 1898.

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. 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 Facts
- •The gray is equivalent to 100 rad, an older unit of absorbed dose.
- •The gray is used in radiation therapy to ensure that the cancerous tissue receives a lethal dose while surrounding healthy tissue receives a much lower dose.
- •Louis Harold Gray was the first scientist to quantify the effects of radiation on living tissue, leading to advancements in cancer treatment.

This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
History & Origin
The curie was named after Marie Curie and Pierre Curie, who were influential researchers in the field of radioactivity in the late 19th and early 20th centuries. Their groundbreaking work led to the discovery of radium and polonium, and they were awarded the Nobel Prize in Physics in 1903. The unit was established in 1910 to provide a standardized measure of radioactivity, reflecting the significance of their contributions to science and medicine.
Etymology: The term 'curie' is derived from the last name of the Curies, a family synonymous with groundbreaking research in radioactivity.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials.
