Femtograys (fGy)
Nanograys (nGy)

Conversion Formula

nGy = fGy × 1.000000000e-6

About Femtograys

The femtogray (fGy) equals 10⁻¹⁵ Gy, used in radiation biology to characterise the dose deposited by a single low-energy Auger electron cascade or a single traversal of a low-LET particle through a cell nucleus. Monte Carlo microdosimetry simulations of targeted radionuclide therapy report subcellular doses at the fGy level. 1 fGy = 10⁻¹⁵ Gy = 10⁻³ pGy.

About Nanograys

The nanogray (nGy) equals 10⁻⁹ Gy. Background cosmic-ray dose rate at sea level is ~0.03-0.05 nGy/s; environmental low-dose-rate studies of DNA damage in cultured cells use nGy doses delivered over days; regulatory derived investigation levels for some radionuclides in food correspond to organ doses in nGy. 1 nGy = 10⁻⁹ Gy = 10⁻³ µGy.
