Frequently Asked Questions

Q. Where should I place my detector?

A. Radon levels vary considerably from location to location within the same building.  Radon frequently enters from the soil underneath the basement or slab, and radon levels are usually highest in the lowest level of the building.

The US EPA uses the terms "lowest level ... suitable for occupancy ... without renovations" in recommending a location to test for radon.  If you have a lowest level with a bedroom, office, or family room, you should set up your radon detector in at least one of these rooms.  If you rarely use the lowest level in your home, set up a radon detector in a frequently used room on the next lowest level.

Place a radon detector in the breathing zone, 2-6 feet above the floor, and away from drafts, exterior walls, windows sumps, drains, or doors.  Radon may enter a building through cracks in the foundation or through sumps or drains and will usually be higher near these entry points.  More detailed instructions are included with each RSSI Alpha-track radon test kit.

Q. What if my detector was moved or opened?

A.  Moving the detector does not effect results if it remains in the breathing zone of the same room.  If your detector has been opened or rattles, call us at 800-762-7774.

Q.  What if I lost my return mailer box?

A. If you lost your mailer, use a padded envelope or small cardboard box and mail it to the address on the detector.
