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.
DecigraydGy
Target UnitThe decigray (dGy) is a unit of measurement for absorbed dose of ionizing radiation, specifically representing one-tenth of a gray (Gy). The gray, the SI unit for absorbed radiation dose, quantifies the energy deposited by ionizing radiation in a material per unit mass. Thus, 1 dGy equals 0.1 Gy, indicating that it measures the amount of radiation energy absorbed by a substance, typically biological tissue, which can lead to biological damage. The decigray is often used in medical applications and radiation therapy to assess dosage levels accurately.
Current Use
The decigray is currently utilized primarily in the fields of radiation therapy and radiology, where precise dosimetric calculations are essential for effective patient treatment. It provides a more granular measurement that aids in calculating dosages for therapeutic and diagnostic procedures, ensuring that patients receive the appropriate amount of radiation while minimizing the risks of overexposure.
Fun Fact
The gray was named after Louis Harold Gray, who was instrumental in the development of radiation therapy techniques.

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.

Decigray
radiation • Non-SI
Definition
The decigray (dGy) is a unit of measurement for absorbed dose of ionizing radiation, specifically representing one-tenth of a gray (Gy). The gray, the SI unit for absorbed radiation dose, quantifies the energy deposited by ionizing radiation in a material per unit mass. Thus, 1 dGy equals 0.1 Gy, indicating that it measures the amount of radiation energy absorbed by a substance, typically biological tissue, which can lead to biological damage. The decigray is often used in medical applications and radiation therapy to assess dosage levels accurately.
History & Origin
The decigray was introduced as part of the metrication of radiation measurement and is derived from the gray, which was adopted in 1975 by the International System of Units (SI) to standardize radiation dose measurements. The gray itself was named after the British scientist Louis Harold Gray, who made significant contributions to the study of radiation and its effects on biological systems, particularly in the context of cancer treatment and radiobiology.
Etymology: The term 'decigray' combines the prefix 'deci-' meaning one-tenth, derived from Latin 'decimus', and 'gray', named after Louis Harold Gray, the pioneer in radiation measurement.
Current Use
The decigray is currently utilized primarily in the fields of radiation therapy and radiology, where precise dosimetric calculations are essential for effective patient treatment. It provides a more granular measurement that aids in calculating dosages for therapeutic and diagnostic procedures, ensuring that patients receive the appropriate amount of radiation while minimizing the risks of overexposure.
💡 Fun Facts
- •The gray was named after Louis Harold Gray, who was instrumental in the development of radiation therapy techniques.
- •One decigray is equivalent to 100 milligrays, a more commonly used unit in some medical settings.
- •Radiation therapy has been used since the early 20th century, with early treatments involving much higher doses than what is considered safe today.
