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.
Teragray SecondTg·s
Target UnitThe teragray second (Tg·s) is a derived unit of measure used in the field of radiation that represents the absorption of one teragray of radiation over a duration of one second. In the context of radiation, the gray (Gy) measures the absorbed dose of ionizing radiation, where one gray is equivalent to the absorption of one joule of radiation energy per kilogram of matter. Therefore, a teragray is one trillion grays, making the teragray second an important unit for quantifying large doses of radiation over time, especially in dosimetry and radiation therapy contexts.
Current Use
The teragray second is primarily used in medical physics and radiological research to quantify high doses of radiation exposure over time. Its application is crucial in radiotherapy treatments for cancer, where precise dosages are essential for effective treatment while minimizing damage to surrounding healthy tissues. This unit aids in the assessment of radiation effects in biological systems and the development of safety protocols in radiation-heavy environments.
Fun Fact
The teragray is one of the highest units of radiation dose used in medical and research settings.

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.

Definition
The teragray second (Tg·s) is a derived unit of measure used in the field of radiation that represents the absorption of one teragray of radiation over a duration of one second. In the context of radiation, the gray (Gy) measures the absorbed dose of ionizing radiation, where one gray is equivalent to the absorption of one joule of radiation energy per kilogram of matter. Therefore, a teragray is one trillion grays, making the teragray second an important unit for quantifying large doses of radiation over time, especially in dosimetry and radiation therapy contexts.
History & Origin
The gray was named after British scientist Louis Harold Gray, who contributed significantly to the understanding of radiation dose measurements in the mid-20th century. The concept of the gray was first adopted by the International Commission on Radiological Protection (ICRP) in 1975, but the teragray second as a specific unit took time to develop for practical applications involving high doses of radiation.
Etymology: The term 'teragray' combines the prefix 'tera-', which denotes a factor of ten to the power of twelve (10^12), with 'gray,' named after Louis Harold Gray.
Current Use
