Unit Explanations
MilligraymGy
Source UnitThe milligray (mGy) is a derived unit of absorbed radiation dose in the International System of Units (SI). It represents the absorption of one milli joule of energy per kilogram of matter. The gray (Gy), the SI unit of radiation dose, is defined as the absorption of one joule of ionizing radiation by one kilogram of matter. Therefore, a milligray is one-thousandth of a gray, which allows for the measurement of smaller doses of radiation that are often encountered in medical and environmental contexts.
Current Use
Milligrays are commonly used in the medical field, especially in radiology and radiation therapy, to quantify the dose of radiation received by patients. For instance, a chest X-ray may deliver a dose of approximately 0.1 mGy, while certain cancer treatments can involve doses in the range of hundreds of milligrays. Additionally, environmental monitoring of radiation exposure in nuclear facilities or during radiological emergencies often utilizes the milligray for reporting purposes. This unit helps ensure the safety of workers and the public by providing clear dosage information.
Fun Fact
The milligray is used to express small doses of radiation that are often encountered in medical imaging.
Attograyag
Target UnitThe attogray (ag) is a subunit of the gray, which measures the absorbed dose of radiation. Specifically, one attogray equals 10^-18 gray, representing an extremely small amount of radiation absorbed by a material. This unit is predominantly used in high-energy physics and radiobiology to quantify minute doses of ionizing radiation, facilitating precise measurements in environments where conventional units may be too large. The attogray allows scientists to express very low levels of radiation exposure, which is essential for understanding biological effects, radiation safety, and medical applications.
Current Use
Today, the attogray is primarily used in research settings, particularly in medical physics, radiobiology, and radiation safety assessments. It is essential for quantifying very low doses of radiation that may not produce immediate biological effects but can have long-term health implications. The attogray is utilized in laboratories, hospitals, and regulatory agencies to ensure accurate monitoring of radiation exposure, especially for sensitive populations such as cancer patients undergoing radiation therapy.
Fun Fact
The attogray is one of the smallest units of radiation dose, underscoring the precision required in modern radiation science.

radiation • Non-SI
Definition
The milligray (mGy) is a derived unit of absorbed radiation dose in the International System of Units (SI). It represents the absorption of one milli joule of energy per kilogram of matter. The gray (Gy), the SI unit of radiation dose, is defined as the absorption of one joule of ionizing radiation by one kilogram of matter. Therefore, a milligray is one-thousandth of a gray, which allows for the measurement of smaller doses of radiation that are often encountered in medical and environmental contexts.
History & Origin
The concept of measuring absorbed radiation began in the early 20th century, as researchers sought to quantify the biological effects of radiation exposure. The gray was adopted as an SI unit in 1975, with the milligray emerging as a convenient subunit for practical applications. The need for precise dosimetry in medical treatments such as radiotherapy and diagnostic imaging led to the widespread use of the milligray, allowing healthcare professionals to monitor and manage patient exposure to ionizing radiation effectively.
Etymology: The term 'gray' is named after the British physicist Louis Harold Gray, who made significant contributions to the understanding of radiation's biological effects.

History & Origin
The attogray originated in the late 20th century, following the establishment of the gray as a standard unit of absorbed dose in 1975 by the International System of Units (SI). The need for smaller units arose as advancements in radiation measurement technology revealed that biological effects can occur at very low radiation doses. This led to the creation of subunits like the attogray to allow for accurate quantification of these minimal doses, particularly in fields such as radiobiology and medical physics.
Etymology: The prefix 'atto-' comes from the Danish word 'atten,' meaning 'eighteen,' indicating a factor of 10^-18. The term 'gray' is named after the British physicist Louis Harold Gray, who contributed significantly to the study of radiation.
