[Batman] Why Doesn't The Microwave Emitter in Batman Begins Make People Explode?

I just watched this movie for the first time the other day and the whole thing kinda revolves around this Microwave Emitter. They explain that the Microwave Emitter is used to vaporize water and turn it into steam which is evident throughout the movie.
So my question is, with people being made up almost entirely of water, why doesn't it instantly make people pop?

The military has actually has microwave-based weaponry. In Afghanistan, Humvees with large dishes on top utilize something called an active denial system, which emit a 95 GHz wave at a particular target, exciting water and fat molecules via dielectric heating, not unlike your microwave oven. Unlike your microwave, however, this is a highly precise weapon which is accurate over distances. It's not omnidirectional. That's important. 

Imagine the device is set to fire a high-powered wave straight downward and is then placed on an elevated train network which runs directly over the water mainlines of a city. As any citizen of Gotham knows, Wayne tower is the heart of the city, where water, power, and transportation all meet, so it's likely that, close to Wayne tower, you're over water mains. 

Now, did anyone explode? We don't really know. Assuming the microwave weapon was pointed downwards at underground mains, anyone standing under the train as it passed overhead likely would have been bombarded with these waves and very well could have exploded.
