Unit Explanations
GrayGy
Source UnitThe gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
Current Use
The gray is widely used in medical fields, particularly in radiation therapy for cancer treatment, where precise dosages are critical for effective treatment while minimizing damage to surrounding healthy tissue. It is also employed in radiological assessments, nuclear power, and safety protocols for radiation workers. Various international organizations, including the International Atomic Energy Agency (IAEA), utilize the gray for consistent communication regarding radiation exposure levels.
Fun Fact
The gray is equivalent to 100 rad, an older unit of absorbed dose.
Disintegration per Seconddps
Target UnitThe disintegration per second (dps) is a non-SI unit used to express the activity of a radioactive substance. It quantifies the number of disintegrations, or decay events, occurring in one second. This unit is essential in nuclear physics and radiological science, providing a clear measure of the radioactivity of materials. One disintegration corresponds to the decay of an unstable atomic nucleus, which transforms into a different state, thereby emitting radiation. The dps is a vital metric for understanding the stability and safety of radioactive materials.
Current Use
The disintegration per second is widely used in nuclear physics, radiology, and health physics to quantify radioactivity. It serves as a key measurement for assessing the safety of radioactive materials in various applications, including medical imaging, cancer treatment, and nuclear power generation. Regulatory agencies use this unit to monitor and control exposure to radiation, ensuring public safety.
Fun Fact
The disintegration per second is closely related to the becquerel, which is the SI unit for radioactivity and is defined as one disintegration per second.

Gray
radiation • SI Unit
Definition
The gray (Gy) is the SI derived unit of absorbed dose of ionizing radiation, defined as the absorption of one joule of radiation energy by one kilogram of matter. It quantifies the amount of energy deposited by radiation in a specified mass of material, which in biological contexts is often human tissue. The gray is crucial in assessing radiation exposure and its potential biological effects, and it serves as a fundamental unit in radiation safety and protection protocols.
History & Origin
The gray was introduced in 1975 by the International System of Units (SI) as the unit of absorbed dose to provide a standardized measurement for radiation exposure. Its creation was a response to the need for a unified system that could facilitate consistency in scientific research and practical applications in radiology, nuclear medicine, and radiation therapy.
Etymology: The unit is named after the British physicist Louis Harold Gray, who made significant contributions to the field of radiation therapy and the study of radiation's effects on biological tissue.
Current Use
The gray is widely used in medical fields, particularly in radiation therapy for cancer treatment, where precise dosages are critical for effective treatment while minimizing damage to surrounding healthy tissue. It is also employed in radiological assessments, nuclear power, and safety protocols for radiation workers. Various international organizations, including the International Atomic Energy Agency (IAEA), utilize the gray for consistent communication regarding radiation exposure levels.
💡 Fun Facts

Disintegration per Second
radiation • Non-SI
Definition
The disintegration per second (dps) is a non-SI unit used to express the activity of a radioactive substance. It quantifies the number of disintegrations, or decay events, occurring in one second. This unit is essential in nuclear physics and radiological science, providing a clear measure of the radioactivity of materials. One disintegration corresponds to the decay of an unstable atomic nucleus, which transforms into a different state, thereby emitting radiation. The dps is a vital metric for understanding the stability and safety of radioactive materials.
History & Origin
The concept of measuring radioactive decay rates emerged in the early 20th century with the discovery of radioactivity by Henri Becquerel in 1896. The term 'disintegration' refers to the breakdown of atomic nuclei, which was later quantified to assess the activity of radioactive materials. The disintegration per second unit became a common way to express these rates, particularly after the establishment of radioactivity as a key field of study in physics and chemistry.
Etymology: The term 'disintegration' comes from the Latin 'disintegratio', meaning 'to break apart or separate'.
Current Use
The disintegration per second is widely used in nuclear physics, radiology, and health physics to quantify radioactivity. It serves as a key measurement for assessing the safety of radioactive materials in various applications, including medical imaging, cancer treatment, and nuclear power generation. Regulatory agencies use this unit to monitor and control exposure to radiation, ensuring public safety.
💡 Fun Facts
- •The disintegration per second is closely related to the becquerel, which is the SI unit for radioactivity and is defined as one disintegration per second.
- •The concept of half-life, which describes the time it takes for half of a radioactive substance to decay, is fundamental in understanding disintegration rates.
- •Radioactive decay is a random process, meaning that it is impossible to predict when a specific atom will disintegrate.
