Nah - haven't felt a need to do so. The lady who owned the house before me was a health physicist (from what I've read, the first female HP), and I'm sure if there was a concern, she had done so.
The house is pretty neat - it's cast concrete slabs and cinderblock. Sits on a concrete foundation, has a hot water (not steam) boiler and piping in the floor for heat during the winter, but no central air - big windows and fans. It's what's called a flat top - composite roof. A family room and master bedroom were added on to it approximately 35 years ago, that portion is standard frame construction, and has a gas furnace and air conditioner on it. Around a total of 1,700 square feet. They weren't built for comfort - in the original part of the structure, the largest of the three original bedrooms is probably 10x15 feet. The room that I use as my office - well, I couldn't put a queen size mattress in here - it would hit all the walls.
Maybe that is why she moved.
