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.
KilograykGy
Target UnitThe kilogray (kGy) is a derived unit of absorbed radiation dose in the International System of Units (SI). It quantifies the amount of energy deposited by ionizing radiation in a mass of material, specifically 1,000 grays (Gy), where one gray is defined as the absorption of one joule of radiation energy by one kilogram of matter. The kilogray is crucial in fields like radiation therapy, radiobiology, and radiation safety, as it provides a standardized measure for assessing the biological effects of radiation exposure.
Current Use
The kilogray is predominantly used in medical radiation therapy and radiation safety to quantify the dose delivered to patients during cancer treatments. It is also used in research to study the effects of radiation on biological systems, including the development of safety standards in nuclear industries. Regulatory agencies across the globe use the kilogray to ensure safe exposure levels in various applications.
Fun Fact
The gray is named after Louis Harold Gray, who conducted pioneering research on radiation doses.

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.

Kilogray
radiation • Non-SI
Definition
The kilogray (kGy) is a derived unit of absorbed radiation dose in the International System of Units (SI). It quantifies the amount of energy deposited by ionizing radiation in a mass of material, specifically 1,000 grays (Gy), where one gray is defined as the absorption of one joule of radiation energy by one kilogram of matter. The kilogray is crucial in fields like radiation therapy, radiobiology, and radiation safety, as it provides a standardized measure for assessing the biological effects of radiation exposure.
History & Origin
The concept of measuring absorbed dose emerged in the mid-20th century as the need for standardizing radiation measurements grew, especially in medical and industrial applications. The gray was adopted as the SI unit in 1975, and the kilogray became its multiple, reflecting larger doses typically encountered in radiation therapy.
Etymology: The term 'gray' is derived from the name of British physicist Louis Harold Gray, who made significant contributions to the understanding of radiation effects on biological tissues.
Current Use
The kilogray is predominantly used in medical radiation therapy and radiation safety to quantify the dose delivered to patients during cancer treatments. It is also used in research to study the effects of radiation on biological systems, including the development of safety standards in nuclear industries.
