Frequently Asked Questions
-
What does converting from picogray to femtogray measure?
-
It measures extremely small absorbed radiation doses, allowing detailed quantification of energy deposited at microscopic or single-event scales.
-
In what fields is this unit conversion most useful?
-
It is primarily used in environmental radiation monitoring, microdosimetry, radiobiology, space instrumentation, and particle physics research.
-
Why is the conversion factor 1000 between pGy and fGy?
-
Because 1 picogray equals 10^-12 gray and 1 femtogray equals 10^-15 gray, the conversion factor reflects that 1 pGy corresponds to 1000 fGy.
Key Terminology
-
Picogray (pGy)
-
An SI-derived unit of absorbed dose equal to 10^-12 gray, measuring energy deposited by ionizing radiation per unit mass.
-
Femtogray (fGy)
-
An SI unit of absorbed dose equal to 10^-15 gray, used to quantify extremely small energy depositions by ionizing radiation.
-
Absorbed Dose
-
The amount of radiation energy deposited in a unit mass of matter.
-
Gray (Gy)
-
The SI unit for absorbed radiation dose, defined as one joule of radiation energy deposited per kilogram of matter.
