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.
TeragrayTGy
Target UnitThe teragray (TGy) is a measurement unit for absorbed radiation dose, where one teragray is equivalent to one trillion grays (1 TGy = 10^12 Gy). The gray (Gy) itself is defined as the absorption of one joule of radiation energy by one kilogram of matter. Teragray is primarily used in contexts involving high doses of radiation, particularly in radiation therapy for cancer treatment, industrial applications, and radiation physics research. This unit helps quantify the energy deposited in biological tissues, critical for assessing potential biological effects of radiation exposure.
Current Use
Today, the teragray is predominantly used in medical physics, particularly in oncology for radiation therapy planning where extremely high doses are administered to target tumors. Moreover, it is also applied in various industrial radiography applications and in research contexts studying the effects of high doses of radiation on biological systems. Its use is critical for understanding radiation exposure limits and ensuring safety in environments where high radiation levels are present.
Fun Fact
The teragray is rarely encountered in everyday life, as it represents extremely high radiation levels typically only found in specialized medical and industrial contexts.

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.

This unit helps quantify the energy deposited in biological tissues, critical for assessing potential biological effects of radiation exposure.
History & Origin
The term 'gray' was introduced in 1975 by the International Commission on Radiation Units and Measurements (ICRU) to replace the older unit, the rad, in an effort to standardize measurements of absorbed dose in radiation science. The prefix 'tera-' signifies a factor of 10^12, originating from the Greek word 'teras,' meaning monster, which reflects the vast scale of this measurement in contexts like high-energy physics and radiological applications.
