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.
TeragrayTGy
Target UnitThe teragray (TGy) is a measurement unit for absorbed radiation dose, where one teragray is equivalent to one trillion grays (1 TGy = 10^12 Gy). The gray (Gy) itself is defined as the absorption of one joule of radiation energy by one kilogram of matter. Teragray is primarily used in contexts involving high doses of radiation, particularly in radiation therapy for cancer treatment, industrial applications, and radiation physics research. This unit helps quantify the energy deposited in biological tissues, critical for assessing potential biological effects of radiation exposure.
Current Use
Today, the teragray is predominantly used in medical physics, particularly in oncology for radiation therapy planning where extremely high doses are administered to target tumors. Moreover, it is also applied in various industrial radiography applications and in research contexts studying the effects of high doses of radiation on biological systems. Its use is critical for understanding radiation exposure limits and ensuring safety in environments where high radiation levels are present.
Fun Fact
The teragray is rarely encountered in everyday life, as it represents extremely high radiation levels typically only found in specialized medical and industrial contexts.

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.

radiation • Non-SI
Definition
The teragray (TGy) is a measurement unit for absorbed radiation dose, where one teragray is equivalent to one trillion grays (1 TGy = 10^12 Gy). The gray (Gy) itself is defined as the absorption of one joule of radiation energy by one kilogram of matter. Teragray is primarily used in contexts involving high doses of radiation, particularly in radiation therapy for cancer treatment, industrial applications, and radiation physics research. This unit helps quantify the energy deposited in biological tissues, critical for assessing potential biological effects of radiation exposure.
History & Origin
The term 'gray' was introduced in 1975 by the International Commission on Radiation Units and Measurements (ICRU) to replace the older unit, the rad, in an effort to standardize measurements of absorbed dose in radiation science. The prefix 'tera-' signifies a factor of 10^12, originating from the Greek word 'teras,' meaning monster, which reflects the vast scale of this measurement in contexts like high-energy physics and radiological applications.
Etymology: The term 'gray' is named after the British physicist Louis Harold Gray, who made significant contributions to the field of radiation measurement and dosimetry.
