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.
NanograynGy
Target UnitThe nanogray (nGy) is a non-SI unit of measurement for absorbed dose of ionizing radiation, equal to 10^-9 grays. The gray (Gy) is the SI unit for measuring the energy absorbed by a material per unit mass, specifically in joules per kilogram. One nanogray represents an infinitesimal amount of energy absorbed, making it a suitable unit for measuring very low doses of radiation encountered in various fields such as medical imaging and radiation therapy. In practical terms, it allows for precise quantification of radiation exposure without overwhelming numbers.
Current Use
The nanogray is widely used in medical fields, particularly in radiology and radiation therapy, for measuring low doses of radiation exposure in patients. It is also used in research settings to quantify radiation in environmental studies and safety assessments, where exact measurements are crucial. Organizations monitoring radiological safety and environmental radiation levels frequently utilize this unit for its precision in low-dose scenarios.
Fun Fact
The gray, from which nanogray is derived, was named after a physicist who studied the effects of radiation on living tissue.

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.
