The Collins WXR-2100 radar system falls well below the 10 mw/cm2 standard. However, it should be noted that there is some disagreement that the 10 mw/cm2 standard is low enough. Microwave ovens represent a more public safety concern and their leakage standard has been set at 4 mw/cm2. The WXR-2100 power density is half or less than that of the microwave oven standard.
Para 6-44.

The referenced FAA Advisory Circular 20–68B is well out of date and does say that WX Radar is dangerous. The old systems were, to a degree; current models - not at all. Your ATPL courses may have used the FAA Circular.
