No, it is not. According to the U.S. Food and Drug Administration, it is very rare to get injuries resulting from standing in front of a microwave. You will be safe as long as the door is latched, as they are designed to keep the radiation inside the microwave. FDA requires that microwave manufacturers ensure that the ovens have two interlock systems that stop the production of microwaves once the door is opened. They also have a monitoring system that stops the appliance from operating if the interlock systems fail. Therefore, as long as the door is closed and is not damaged, you will be safe.
