Does the tunnel slightly dry sterilizer have radiation damage to people?

Usually, the equipment is equipped with microwave suppressor, so it is harmless to be one meter away from the equipment.

Just don't put your head and hands into the equipment during the operation, and there will be no problem.

If you are not at ease, you can also buy a simple microwave leak detector. For equipment testing, usually equipment manufacturers will improve the leakage of equipment before leaving the factory.
