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.
Exagray SecondEg·s
Target UnitThe exagray second (Eg·s) is a derived unit of measurement used in the field of radiation to quantify the amount of energy absorbed by matter from ionizing radiation over a given time period. It is defined as one quintillion gray-seconds, where the gray (Gy) is the SI unit of absorbed radiation dose, equivalent to one joule per kilogram. The exagray second is often utilized in high-energy physics and medical applications involving significant radiation exposure, allowing for a clearer understanding of doses over extensive periods.
Current Use
The exagray second is primarily used in high-energy physics and medical radiation therapy to quantify large doses of radiation exposure. Its utilization is crucial in monitoring and managing radiation levels in environments such as nuclear power plants, hospitals, and research laboratories. As the scale of radiation applications increases, the exagray second serves as a vital unit for ensuring safety and compliance with radiation exposure limits.
Fun Fact
The exagray is primarily used in scenarios involving extreme radiation doses, vastly exceeding typical medical dosages.

Gray
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.

Exagray Second
radiation • Non-SI
Definition
The exagray second (Eg·s) is a derived unit of measurement used in the field of radiation to quantify the amount of energy absorbed by matter from ionizing radiation over a given time period. It is defined as one quintillion gray-seconds, where the gray (Gy) is the SI unit of absorbed radiation dose, equivalent to one joule per kilogram. The exagray second is often utilized in high-energy physics and medical applications involving significant radiation exposure, allowing for a clearer understanding of doses over extensive periods.
History & Origin
The concept of measuring radiation doses emerged in the early 20th century with advances in nuclear physics and radiation medicine. The gray was introduced in 1975 as the SI unit of absorbed dose, derived from the need to quantify radiation exposure accurately. The prefix 'exa-' was subsequently adopted to express large quantities of radiation doses for specific high-energy applications, leading to the establishment of the exagray second.
Etymology: The term 'exa' is a metric prefix denoting a factor of 10^18, derived from the Greek word 'hex' meaning 'six', indicating the sixth power of 10. The term 'gray' honors the British physicist Louis Harold Gray, a pioneer in the study of radiation dose.
