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.
Dekagray SeconddagĀ·s
Target UnitThe dekagray second (dagĀ·s) is a derived unit in the International System of Units (SI) that quantifies the absorption of ionizing radiation. Specifically, it represents the absorption of 10 gray-seconds of radiation energy by a mass of material. The gray (Gy) itself is defined as the absorption of one joule of radiation energy per kilogram of matter. Thus, the dekagray second indicates a significant interaction between radiation and matter, facilitating assessments in radiation exposure and its biological effects over a specified duration.
Current Use
The dekagray second is utilized primarily in the context of radiation therapy, where precise dosages are critical for effective treatment. In medical imaging and diagnostics, it helps in assessing the risks associated with exposure to radiation. The unit is also relevant in nuclear power industries, environmental monitoring, and research involving radioactive materials. Its application spans globally, particularly in nations with advanced medical and scientific infrastructures.
Fun Fact
The gray is named after British physicist Louis Harold Gray, who contributed to the study of radiation in the early 20th century.

Dekagray Second
radiation ā¢ Non-SI
Definition
The dekagray second (dagĀ·s) is a derived unit in the International System of Units (SI) that quantifies the absorption of ionizing radiation. Specifically, it represents the absorption of 10 gray-seconds of radiation energy by a mass of material. The gray (Gy) itself is defined as the absorption of one joule of radiation energy per kilogram of matter. Thus, the dekagray second indicates a significant interaction between radiation and matter, facilitating assessments in radiation exposure and its biological effects over a specified duration.
History & Origin
The concept of measuring radiation dose began in the early 20th century with the discovery of X-rays and radioactivity. The gray was established as a standard unit in 1975 due to the need for a consistent way to quantify radiation exposure and its effects on human tissue. The dekagray second emerged as a convenient subunit, allowing for easier calculations in various scientific and medical applications. The standardization of these units was crucial for safety protocols in radiation therapy and nuclear medicine.
Etymology: The term 'deka' is derived from the Greek word 'deka', meaning ten, indicating that one dekagray is ten times the base unit, the gray.
Current Use
The dekagray second is utilized primarily in the context of radiation therapy, where precise dosages are critical for effective treatment. In medical imaging and diagnostics, it helps in assessing the risks associated with exposure to radiation. The unit is also relevant in nuclear power industries, environmental monitoring, and research involving radioactive materials. Its application spans globally, particularly in nations with advanced medical and scientific infrastructures.
