About Micrograys

The microgray (µGy) equals 10⁻⁶ Gy. Typical organ doses from diagnostic X-ray procedures: chest X-ray ~0.01-0.1 µGy; mammography mean glandular dose ~1-3 mGy (i.e. 1000-3000 µGy); dental bitewing ~1-5 µGy. IAEA Safety Reports quote entrance surface doses in µGy for patient dose surveys. 1 µGy = 10⁻⁶ Gy.

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.
