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.
Rad Secondrad·s
Target UnitThe rad second (rad·s) is a non-SI unit of radiation dose that combines the unit of absorbed dose, the rad, with time measured in seconds. One rad is defined as the absorption of 100 ergs of radiation energy per gram of matter, translating to a dose of 0.01 joules per kilogram. Therefore, the rad second quantifies the amount of radiation exposure over a specific time interval. This unit is crucial in fields such as radiobiology and medical physics, where understanding both the dose and duration of radiation exposure is vital for assessing biological effects and treatment planning.
Current Use
The rad second is primarily used in medical physics, particularly in radiation therapy, where the timing of radiation delivery is crucial for treatment efficacy. It is also used in radiobiology to evaluate the effects of radiation exposure on living tissues over time. Although declining in SI usage, it is still referenced in certain regulatory contexts and in the assessment of occupational exposure in radiation-related industries, especially in the United States.
Fun Fact
The rad is still commonly used in the U.S. despite the SI unit gray being the standard worldwide.

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.

Rad Second
radiation • Non-SI
Definition
The rad second (rad·s) is a non-SI unit of radiation dose that combines the unit of absorbed dose, the rad, with time measured in seconds. One rad is defined as the absorption of 100 ergs of radiation energy per gram of matter, translating to a dose of 0.01 joules per kilogram. Therefore, the rad second quantifies the amount of radiation exposure over a specific time interval. This unit is crucial in fields such as radiobiology and medical physics, where understanding both the dose and duration of radiation exposure is vital for assessing biological effects and treatment planning.
History & Origin
The rad was first introduced in 1956 as a part of the American National Standards Institute (ANSI) standards for measuring radiation exposure. The rad second was subsequently developed for practical applications in radiation therapy and safety, where the duration of exposure is a critical factor in assessing potential biological impacts. It provides a means to quantify accumulated dose over time, which is essential in both clinical and research settings.
Etymology: The term 'rad' is derived from 'radiation absorbed dose', while 'second' is a standard unit of time in the International System of Units (SI).
Current Use
The rad second is primarily used in medical physics, particularly in radiation therapy, where the timing of radiation delivery is crucial for treatment efficacy. It is also used in radiobiology to evaluate the effects of radiation exposure on living tissues over time. Although declining in SI usage, it is still referenced in certain regulatory contexts and in the assessment of occupational exposure in radiation-related industries, especially in the United States.
💡 Fun Facts
- •The rad is still commonly used in the U.S. despite the SI unit gray being the standard worldwide.
- •The term 'rad' was not officially defined until 1956, showing the evolution of radiation measurement standards.
- •One rad is equivalent to a dose that produces a specific biological effect, making it crucial in cancer treatment planning.
