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.
CurieCi
Target UnitThe curie (symbol: Ci) is a non-SI unit of radioactivity that quantifies the activity of a radioactive substance. It is defined as the amount of radioactive material that produces 3.7 × 10^10 disintegrations per second, equivalent to the radioactivity of 1 gram of radium-226. The curie is named in honor of Marie Curie and her husband Pierre Curie, who conducted pioneering research on radioactivity. This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials. Despite the adoption of the SI unit becquerel, the curie remains popular in the United States and in various medical and industrial applications.
Fun Fact
The curie was originally based on the activity of radium, which was discovered by the Curies in 1898.

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.

This unit is widely used in nuclear medicine, radiobiology, and radiation safety, providing a measure that allows for the assessment of radioactive decay and its implications for health and environment.
History & Origin
The curie was named after Marie Curie and Pierre Curie, who were influential researchers in the field of radioactivity in the late 19th and early 20th centuries. Their groundbreaking work led to the discovery of radium and polonium, and they were awarded the Nobel Prize in Physics in 1903. The unit was established in 1910 to provide a standardized measure of radioactivity, reflecting the significance of their contributions to science and medicine.
Etymology: The term 'curie' is derived from the last name of the Curies, a family synonymous with groundbreaking research in radioactivity.
Current Use
Today, the curie is primarily used in nuclear medicine, where it helps quantify the activity of radioactive pharmaceuticals used in diagnostic imaging and therapy. It is also used in radiation safety assessments and environmental monitoring, providing critical data for occupational health and safety regarding exposure to radioactive materials.
