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.
CurieCi
Target UnitThe curie (symbol: Ci) is a non-SI unit of radioactivity that quantifies the activity of a radioactive substance. It is defined as the amount of radioactive material that produces 3.7 × 10^10 disintegrations per second, equivalent to the radioactivity of 1 gram of radium-226. The curie is named in honor of Marie Curie and her husband Pierre Curie, who conducted pioneering research on radioactivity. This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials. Despite the adoption of the SI unit becquerel, the curie remains popular in the United States and in various medical and industrial applications.
Fun Fact
The curie was originally based on the activity of radium, which was discovered by the Curies in 1898.

Milligray
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. 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 Facts
- •The milligray is used to express small doses of radiation that are often encountered in medical imaging.
- •Healthcare professionals often use the term 'milligray' to discuss radiation exposure levels, ensuring better communication among teams.
- •One milligray is equivalent to 1,000 micrograys (µGy), making it easier to express doses in various contexts.

This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
History & Origin
The curie was named after Marie Curie and Pierre Curie, who were influential researchers in the field of radioactivity in the late 19th and early 20th centuries. Their groundbreaking work led to the discovery of radium and polonium, and they were awarded the Nobel Prize in Physics in 1903. The unit was established in 1910 to provide a standardized measure of radioactivity, reflecting the significance of their contributions to science and medicine.
Etymology: The term 'curie' is derived from the last name of the Curies, a family synonymous with groundbreaking research in radioactivity.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials.
