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.
ExagrayEgray
Target UnitThe exagray (Egray) is a unit of measurement for absorbed radiation dose, defined as the absorption of one joule of radiation energy per kilogram of matter. One exagray equals 10^18 grays, where one gray corresponds to one joule of energy absorbed per kilogram. This unit is primarily used in high-energy physics, radiation therapy, and dosimetry. The exagray quantifies the immense amounts of energy that can be deposited in matter, making it crucial for understanding and quantifying radiation effects at extreme levels.
Current Use
Exagray is primarily utilized in high-energy physics experiments, radiological assessments, and advanced radiation therapy protocols, where extremely high doses of radiation are administered to achieve therapeutic effects. It serves as a standard for quantifying radiation levels in large-scale particle accelerator experiments, such as those conducted at CERN. Additionally, the exagray is relevant in nuclear science, where it helps communicate doses received in experimental conditions.
Fun Fact
The exagray is a part of the International System of Units (SI), which standardizes measurements across scientific disciplines.

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.
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.

History & Origin
The concept of measuring radiation doses began in the early 20th century with the discovery of radioactivity. The gray was adopted as the SI unit for absorbed dose in 1975, derived from the earlier unit rad. The exagray was introduced later to accommodate measurements at extremely high doses, particularly relevant in fields such as particle physics and large-scale radiation therapy. This evolution reflects the growing need for precise measurements in increasingly powerful radiation environments.
Etymology: The term 'exagray' combines the prefix 'exa-', denoting a factor of 10^18, with 'gray', named after British physicist Louis Harold Gray, who contributed significantly to radiation dosimetry.
