According to the US Food and Drug Administration, the radiation emitted by X-ray machines is 1 millirad
or less, while the average level we are exposed to in the natural environment is 360 millirad
every year, reported the South China Morning Post.
While the latter offers a monochrome image, it does so with a resolution of one millirad
or approximately 6400 pixels around the vehicle down to the near-infrared spectrum (1.1 micron), although full darkness vision is possible due to an integrated invisible spectrum illuminator.
After an exposure greater than 10 mGy (1000 millirad
), the unborn baby has a fractional risk of developing cancer in childhood.
According to LNT, if a 1 Gy (100 rad) dose gives a cancer risk R, the risk from a dose of 0.01 Gy (1 rad) is R/ 100, the risk from 0.00001 Gy (1 millirad
) is R/100,000, and so on.
