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.
Picogray Secondpg·s
Target UnitThe picogray second (pg·s) is a derived unit of radiation dose in the International System of Units (SI) that represents the absorption of one trillionth (10^-12) of a gray over a second. The gray is the SI unit of absorbed radiation dose, defined as the absorption of one joule of radiation energy by one kilogram of matter. Therefore, one picogray second signifies an extremely small amount of radiation energy absorbed by matter within the timeframe of one second, making it a useful unit in fields requiring precise measurements of low radiation doses.
Current Use
The picogray second is primarily used in medical physics, radiation safety, and environmental science. It allows for precise measurement of radiation doses in situations where exposure levels are low. For example, in radiology, where patients are exposed to minimal radiation during diagnostic imaging, the picogray second provides a more accurate representation of the dosage received. Similarly, in nuclear medicine, it assists in monitoring patient exposure during therapeutic procedures, ensuring it remains within safe limits.
Fun Fact
The picogray second is so small that it is often used in specialized fields to measure exposures that are otherwise undetectable.

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.
