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.

ParkerP

Target Unit

The Parker is a unit used to measure radiation exposure, specifically in terms of electrical charge produced by ionizing radiation in a specified volume of air. It quantifies the biological effects of radiation on living tissues, particularly in medical and environmental contexts. One Parker represents the amount of ionizing radiation that produces 1 coulomb of charge in 1 kilogram of air at standard conditions. This unit is crucial for assessing radiation safety and exposure limits.

1 P = 1 C/kg (in air)

Current Use

Currently, the Parker is widely used in medical settings, particularly in radiology and oncology, to measure patient exposure during imaging procedures and treatments. It is also utilized in research laboratories and nuclear facilities to ensure compliance with safety regulations. The Parker serves as a vital tool for radiation safety officers and health physicists in assessing both occupational and environmental exposure levels.

Fun Fact

The Parker unit is named after Dr. John Parker, who made significant contributions to radiation safety.

Gray

radiationSI 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.
