Driving in your car with the headlights on gives you more exposure to electromagnetic energy than flying with the weather radar on, (in both cases, virtually nil).
Same sort of emissions*, same sort of power, same physical set-up with the transmitters mounted in front of reflectors facing away from you, and which are mounted in front of a metal bulkhead between them and you.
No danger.
*Visible light and microwaves are both electromagnetic waves on the electromagnetic spectrum. Visible light has a higher frequency and energy than microwaves. Microwaves as used by radars are not energetic enough to cause ionisation, (potential tissue damage). Only when you get up to X-rays (in your hospital, and way above visible light), are the energies enough to disrupt molecular bonds.
