Unit Explanations

GrayGy

Source Unit

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.

1 Gy = 1 J/kg

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.

TerabecquerelTBq

Target Unit

The terabecquerel (TBq) is a unit of radioactivity in the International System of Units (SI). It quantifies the activity of a radioactive substance, specifically measuring the number of disintegrations or decay events that occur per second. One terabecquerel is equal to 10^12 (1 trillion) disintegrations per second. The unit is named after Henri Becquerel, who discovered radioactivity in 1896. The terabecquerel is commonly used in nuclear medicine, radiation safety, and research involving radioactive materials.

1 TBq = 10^12 Bq

Current Use

Today, the terabecquerel is widely used in various fields including nuclear medicine, environmental monitoring, and radiation safety. It helps quantify the radioactivity of materials used in diagnostic imaging and cancer treatment, as well as in research involving radioactive isotopes. Regulatory bodies, such as the International Atomic Energy Agency (IAEA), use the terabecquerel to set safety standards and limits in handling radioactive substances. Its application extends to monitoring nuclear waste and ensuring compliance with safety protocols in nuclear facilities.

Fun Fact

The becquerel, the base unit for radioactivity, was named after Henri Becquerel in recognition of his groundbreaking work in radioactivity.

Terabecquerel

radiationNon-SI

Definition

The terabecquerel (TBq) is a unit of radioactivity in the International System of Units (SI). It quantifies the activity of a radioactive substance, specifically measuring the number of disintegrations or decay events that occur per second. One terabecquerel is equal to 10^12 (1 trillion) disintegrations per second. The unit is named after Henri Becquerel, who discovered radioactivity in 1896. The terabecquerel is commonly used in nuclear medicine, radiation safety, and research involving radioactive materials.

History & Origin

The terabecquerel was introduced in the late 20th century as a larger unit of measurement to quantify high levels of radioactivity more conveniently. It builds on the foundation set by the becquerel (Bq), the SI unit named after Henri Becquerel, who first observed radioactivity. The need for larger units such as the terabecquerel arose as advancements in nuclear technology and medical applications increased the production and use of radioactive isotopes, necessitating a more practical scale for measurement.

Etymology: The term 'terabecquerel' is derived from the prefix 'tera-', which denotes a factor of 10^12, and 'becquerel', named after Henri Becquerel, who is credited with the discovery of radioactivity.
