Convert Rads to Nanograys
Convert Rads (rad) to Nanograys (nGy) instantly and accurately.
Conversion Formula
nGy = rad × 10000000
About Rads
The rad (rad) equals exactly 0.01 Gy = 100 erg/g. The pre-SI unit of absorbed dose, defined by the ICRU in 1953, still widely used in the US in radiation therapy (cGy = rad numerically), radiation biology, and NRC regulations. Whole-body 50% lethal dose (LD50) for humans ~350-450 rad. 1 rad = 0.01 Gy = 1 cGy.
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.
