Convert Femtograys to Microrads
Convert Femtograys (fGy) to Microrads (µrad) instantly and accurately.
Conversion Formula
µrad = fGy × 1.000000000e-7
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 Microrads
The microrad (µrad) equals 10⁻⁶ rad = 10⁻⁸ Gy. Used in legacy US radiological instrumentation calibration documentation for very low-level survey instrument thresholds; some older NRC and EPA radiation protection records quote environmental dose rates in µrad/h when modern instruments report nGy/h. 1 µrad = 10⁻⁸ Gy = 10⁻² µGy.
