Unit Explanations
Radiation Absorbed Doserad
Source UnitThe rad (radiation absorbed dose) is a non-SI unit that quantifies the amount of ionizing radiation energy absorbed by a material, particularly human tissue. One rad is equivalent to the absorption of 0.01 joules of energy per kilogram of matter. This unit is mainly used in the fields of radiation protection and radiological science to assess the biological effects of radiation exposure. The concept of the rad was developed to help in the understanding of the dose-response relationship of radiation exposure and its potential biological effects.
Current Use
The rad is currently used primarily in the United States for measuring absorbed radiation in medical, environmental, and occupational settings. It aids in determining appropriate radiation exposure levels for patients undergoing treatments such as cancer therapy and helps in assessing risks in occupational settings involving radiation.
Fun Fact
The rad was once widely used in medical settings, particularly in oncology, before the adoption of the gray.
Milliradmrad
Target UnitThe millirad (mrad) is a unit of measure for absorbed dose of ionizing radiation, defined as one thousandth of a rad. The rad is an older unit that quantifies the amount of energy deposited by radiation in a mass of material, particularly biological tissue. One millirad corresponds to an absorbed dose of 0.001 rad, which is equivalent to 0.01 gray (Gy). The unit is often used in contexts related to radiation safety and health physics, providing a convenient scale for low-dose measurements.
Current Use
The millirad is commonly used in the fields of radiation therapy, radiology, and nuclear medicine to detail radiation doses received by patients or workers. While the gray is the SI unit for absorbed dose, the millirad is still found in some older medical literature and protocols, particularly in the United States. It is also used in safety standards to quantify exposure limits in occupational settings.
Fun Fact
The millirad is often used in conjunction with the more commonly known gray and rad units.

Radiation Absorbed Dose
radiation • Non-SI
Definition
The rad (radiation absorbed dose) is a non-SI unit that quantifies the amount of ionizing radiation energy absorbed by a material, particularly human tissue. One rad is equivalent to the absorption of 0.01 joules of energy per kilogram of matter. This unit is mainly used in the fields of radiation protection and radiological science to assess the biological effects of radiation exposure. The concept of the rad was developed to help in the understanding of the dose-response relationship of radiation exposure and its potential biological effects.
History & Origin
The rad was introduced in the 1950s during the early advancements in radiation therapy and protection. It was developed to provide a clear measurement of absorbed doses in biological tissues, allowing for better assessments of radiation risks. The unit was widely adopted in various fields, including medicine, environmental science, and nuclear safety.
Etymology: The term 'rad' is derived from the phrase 'radiation absorbed dose', highlighting its purpose in measuring radiation absorption.
Current Use
The rad is currently used primarily in the United States for measuring absorbed radiation in medical, environmental, and occupational settings. It aids in determining appropriate radiation exposure levels for patients undergoing treatments such as cancer therapy and helps in assessing risks in occupational settings involving radiation.
💡 Fun Facts
- •The rad was once widely used in medical settings, particularly in oncology, before the adoption of the gray.
- •One rad is equivalent to 0.01 gray, making it easier for professionals familiar with historical measurements to understand modern units.
- •The rad is still used alongside the gray in certain educational and practical contexts, particularly in the United States.

Millirad
radiation • Non-SI
Definition
The millirad (mrad) is a unit of measure for absorbed dose of ionizing radiation, defined as one thousandth of a rad. The rad is an older unit that quantifies the amount of energy deposited by radiation in a mass of material, particularly biological tissue. One millirad corresponds to an absorbed dose of 0.001 rad, which is equivalent to 0.01 gray (Gy). The unit is often used in contexts related to radiation safety and health physics, providing a convenient scale for low-dose measurements.
History & Origin
The millirad originated from the rad, which was introduced in the late 1950s as a unit to quantify the biological effects of radiation in terms of energy deposited in matter. The need for smaller, more manageable units like the millirad arose as radiation exposure measurements became increasingly important, particularly in medical and occupational settings.
Etymology: The term 'millirad' combines the prefix 'milli-', meaning one thousandth, with 'rad', which stands for 'radiation absorbed dose'.
Current Use
The millirad is commonly used in the fields of radiation therapy, radiology, and nuclear medicine to detail radiation doses received by patients or workers. While the gray is the SI unit for absorbed dose, the millirad is still found in some older medical literature and protocols, particularly in the United States. It is also used in safety standards to quantify exposure limits in occupational settings.
💡 Fun Facts
- •The millirad is often used in conjunction with the more commonly known gray and rad units.
- •The rad was initially used to determine the effects of radiation on human tissue, which led to the development of the millirad.
- •Despite the metric system's growth, many institutions in the US still use the millirad for certain applications.
