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.
ExagrayEgray
Target UnitThe exagray (Egray) is a unit of measurement for absorbed radiation dose, defined as the absorption of one joule of radiation energy per kilogram of matter. One exagray equals 10^18 grays, where one gray corresponds to one joule of energy absorbed per kilogram. This unit is primarily used in high-energy physics, radiation therapy, and dosimetry. The exagray quantifies the immense amounts of energy that can be deposited in matter, making it crucial for understanding and quantifying radiation effects at extreme levels.
Current Use
Exagray is primarily utilized in high-energy physics experiments, radiological assessments, and advanced radiation therapy protocols, where extremely high doses of radiation are administered to achieve therapeutic effects. It serves as a standard for quantifying radiation levels in large-scale particle accelerator experiments, such as those conducted at CERN. Additionally, the exagray is relevant in nuclear science, where it helps communicate doses received in experimental conditions.
Fun Fact
The exagray is a part of the International System of Units (SI), which standardizes measurements across scientific disciplines.

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

Exagray
radiation • Non-SI
Definition
The exagray (Egray) is a unit of measurement for absorbed radiation dose, defined as the absorption of one joule of radiation energy per kilogram of matter. One exagray equals 10^18 grays, where one gray corresponds to one joule of energy absorbed per kilogram. This unit is primarily used in high-energy physics, radiation therapy, and dosimetry. The exagray quantifies the immense amounts of energy that can be deposited in matter, making it crucial for understanding and quantifying radiation effects at extreme levels.
History & Origin
The concept of measuring radiation doses began in the early 20th century with the discovery of radioactivity. The gray was adopted as the SI unit for absorbed dose in 1975, derived from the earlier unit rad. The exagray was introduced later to accommodate measurements at extremely high doses, particularly relevant in fields such as particle physics and large-scale radiation therapy. This evolution reflects the growing need for precise measurements in increasingly powerful radiation environments.
Etymology: The term 'exagray' combines the prefix 'exa-', denoting a factor of 10^18, with 'gray', named after British physicist Louis Harold Gray, who contributed significantly to radiation dosimetry.
