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.
Hectogray SecondhGy·s
Target UnitThe hectogray second (hGy·s) is a derived unit of measurement that represents the amount of energy absorbed by a material from ionizing radiation over a specific period of time. One hectogray is equal to 100 grays (Gy), which measures the energy absorbed per unit mass of an absorbing medium. When combined with time, this unit provides valuable information on the total radiation exposure a material has received during a specific duration, making it particularly relevant in radiation therapy and radiological protection contexts.
Current Use
Currently, the hectogray second is used primarily in medical physics and radiation therapy, where it assists in calculating total radiation doses delivered to patients over treatment periods. Its applications extend to radiation safety assessments in various industrial and research settings, as accurate dose-time measurements are crucial for compliance with safety regulations and effective treatment protocols.
Fun Fact
The gray is named after British physicist Louis Harold Gray, who contributed significantly to radiation research.

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.

Hectogray Second
radiation • Non-SI
Definition
The hectogray second (hGy·s) is a derived unit of measurement that represents the amount of energy absorbed by a material from ionizing radiation over a specific period of time. One hectogray is equal to 100 grays (Gy), which measures the energy absorbed per unit mass of an absorbing medium. When combined with time, this unit provides valuable information on the total radiation exposure a material has received during a specific duration, making it particularly relevant in radiation therapy and radiological protection contexts.
History & Origin
The concept of measuring absorbed doses of radiation dates back to the early 20th century as scientists began to understand the effects of radiation on biological tissues. The gray was adopted as the SI unit of absorbed dose in 1975, with the hectogray being a derived unit for larger doses. The extension of the gray to include time, forming the hectogray second, provides a means to quantify the exposure over time, particularly in therapeutic and safety applications.
Etymology: The term 'hecto' originates from the Greek word 'hekaton,' meaning one hundred, indicating that one hectogray is equivalent to one hundred grays.
Current Use
Currently, the hectogray second is used primarily in medical physics and radiation therapy, where it assists in calculating total radiation doses delivered to patients over treatment periods. Its applications extend to radiation safety assessments in various industrial and research settings, as accurate dose-time measurements are crucial for compliance with safety regulations and effective treatment protocols.
💡 Fun Facts
- •The gray is named after British physicist Louis Harold Gray, who contributed significantly to radiation research.
- •Measuring radiation dose in terms of time allows for better scheduling of treatment protocols in oncology.
- •The concept of radiation dose has evolved to consider both the type of radiation and the biological effects on different tissues.
