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.
Megagray SecondMg·s
Target UnitThe megagray second (Mg·s) is a derived unit of radiation dose that combines the concepts of absorbed dose and time. One megagray is equivalent to one million grays, where a gray (Gy) is defined as the absorption of one joule of radiation energy per kilogram of matter. Thus, one megagray second represents the absorption of one million joules of radiation energy per kilogram over the duration of one second. This unit is significant in fields where radiation exposure is measured for both its intensity and its duration.
Current Use
The megagray second is utilized primarily in radiation therapy, nuclear medicine, and research involving high levels of radiation exposure. It aids in quantifying the dosimetric impact of radiation on biological tissues and materials. Facilities such as hospitals and research laboratories employ this unit to measure and calibrate radiation doses in treatment protocols and experimental setups.
Fun Fact
A dose of 1 megagray is 1,000,000 times the standard radiation dose that is considered lethal to humans.

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.
