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 Ergs per gram

The erg per gram (erg/g) equals exactly 10⁻⁴ Gy and is the CGS-Gaussian unit of absorbed dose. Because 1 rad was originally defined as 100 erg/g, this unit is directly linked to the historical radiation system. Still found in older nuclear physics and health physics texts predating SI adoption. 1 erg/g = 10⁻⁴ Gy = 0.1 mGy.
