Unit Explanations
Gray SecondGy·s
Source UnitThe gray second (Gy·s) is a derived unit of measurement in the International System of Units (SI), representing the absorption of one joule of radiation energy per kilogram of matter, occurring over a duration of one second. This unit is crucial in the field of radiation physics, as it quantifies the biological effect of ionizing radiation absorbed by living tissue. The gray second is particularly relevant in medical treatments such as radiotherapy, where precise dosages are critical for effective cancer treatment.
Current Use
The gray second is predominantly used in the fields of medical physics, radiation therapy, and radiobiology. It serves as a critical measurement for determining the safe and effective doses of radiation administered to patients undergoing cancer treatment. Additionally, it is utilized in research settings to study radiation effects on biological systems, ensuring compliance with safety standards in environments where radiation exposure occurs.
Fun Fact
The gray is the SI unit that replaced the older, less precise units like the rad, making calculations more standardized.
Femtogray Secondfg·s
Target UnitThe femtogray second (fg·s) is a derived unit of measurement that combines the gray (a unit of ionizing radiation dose) with seconds (a measure of time). One femtogray is equal to 10^-15 grays, making the femtogray second a very small unit applicable in contexts where very low levels of radiation exposure are measured over very short time intervals. This unit is particularly useful in scientific research involving radiation effects at nanoscale levels, enabling precise calculations of radiation exposure and its biological impacts over time.
Current Use
Femtogray seconds are primarily used in scientific research where extremely low levels of radiation are analyzed over short durations. This is particularly relevant in fields such as radiobiology, nuclear medicine, and radiation therapy, where understanding the effects of low-dose radiation over time is crucial for developing safety protocols and treatment plans.
Fun Fact
The femtogray is one of the smallest units of radiation, allowing for extremely precise measurements.

Gray Second
radiation • Non-SI
Definition
The gray second (Gy·s) is a derived unit of measurement in the International System of Units (SI), representing the absorption of one joule of radiation energy per kilogram of matter, occurring over a duration of one second. This unit is crucial in the field of radiation physics, as it quantifies the biological effect of ionizing radiation absorbed by living tissue. The gray second is particularly relevant in medical treatments such as radiotherapy, where precise dosages are critical for effective cancer treatment.
History & Origin
The gray second was introduced in 1975 as part of the International System of Units (SI) to standardize the measurement of absorbed radiation doses. It was named in honor of the British physicist Louis Harold Gray, who made significant contributions to the field of radiation biology. The development of this unit came from the need for a coherent system to evaluate the effects of radiation on living organisms, especially after the increased use of ionizing radiation in medicine and industry.
Etymology: The term 'gray' is derived from the last name of Louis Harold Gray, while 'second' refers to the unit of time, indicating the duration over which the radiation dose is measured.
