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.
Nanogray SecondnGy·s
Target UnitThe nanogray second (nGy·s) is a derived unit of measurement that quantifies the absorbed dose of ionizing radiation over time, specifically at a scale of one billionth of a gray per second. The gray (Gy) is the SI unit for absorbed radiation dose, defined as the absorption of one joule of radiation energy by one kilogram of matter. Therefore, one nanogray corresponds to one billionth of a gray, making it a suitable unit for measuring minute doses of radiation in fields such as health physics and radiation safety.
Current Use
The nanogray second is predominantly used in the fields of medical physics, radiology, and radiation safety. It allows for the measurement of low-dose radiation exposures, such as those encountered in diagnostic imaging or radiotherapy. Regulatory bodies and health organizations utilize this unit to ensure that radiation doses are kept within safe limits for both patients and healthcare providers.
Fun Fact
The gray is named in honor of Louis Harold Gray, who was instrumental in developing methods for measuring radiation doses.

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.
