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.
GigabecquerelGBq
Target UnitThe gigabecquerel (GBq) is a derived unit of radioactivity in the International System of Units (SI), defined as 10^9 (one billion) disintegrations or decays per second. It measures the rate at which a radioactive source emits radiation, reflecting the intensity of radioactivity. The becquerel (Bq), the SI base unit from which the gigabecquerel is derived, is named after the French physicist Henri Becquerel, who discovered radioactivity in 1896. The gigabecquerel is used to quantify large amounts of radioactive material, making it particularly useful in nuclear medicine, research, and industry.
Current Use
Currently, the gigabecquerel is extensively used in medical diagnostics and treatment, particularly in nuclear medicine where it quantifies the radioactivity of radiopharmaceuticals. It is essential for determining safe doses in patient treatments and ensuring compliance with safety regulations. Additionally, it is used in environmental monitoring to measure contamination levels.
Fun Fact
The gigabecquerel is equivalent to 1 billion disintegrations per second, which makes it a practical unit for measuring high levels of radioactivity.

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.
