Apple Scientists Disclose Self-Driving Car Research (reuters.com)
Apple's first publicly disclosed paper on autonomous vehicles has been posted online by the company's computer scientists. The research describes a new software approach called "VoxelNet" that helps computers detect three-dimensional objects like cyclists and pedestrians while using fewer sensors. Reuters reports: The paper by Yin Zhou and Oncel Tuzel, submitted on Nov. 17 to independent online journal arXiv, is significant because Apple's famed corporate secrecy around future products has been seen as a drawback among artificial intelligence and machine learning researchers. The scientists proposed a new software approach called "VoxelNet" for helping computers detect three-dimensional objects.
Self-driving cars often use a combination of normal two-dimensional cameras and depth-sensing "LiDAR" units to recognize the world around them. While the units supply depth information, their low resolution makes it hard to detect small, faraway objects without help from a normal camera linked to it in real time. But with new software, the Apple researchers said they were able to get "highly encouraging results" in spotting pedestrians and cyclists with just LiDAR data. They also wrote they were able to beat other approaches for detecting three-dimensional objects that use only LiDAR. The experiments were computer simulations and did not involve road tests.

Microwave transmitters do not emit ionizing radiation. Early Klystron based generators did produce X-Rays, but they were largely superseded by designs which did not produce X-Rays as this is a loss of useful output power/transmission inefficiency.
Regardless, in terms of danger; 25mW/cm^2 is where you start feeling heat on your skin after several minutes. Pain is at 1W/cm^2. Burning (ie skin temperature going above 42C) happens at 2.5W/cm^2 but that usually takes 5 minutes or more of exposure.
Radar systems used in cars typically have an output level of 10mW at the source - this decreases as the square of the distance.
A million cars != a million "ionising radiation units". Or maybe they do as I'm assuming "ionising" is a spelling mistake.
