Common questions8 questions, answered from the figures above
Are radon levels high in Saipan County?
No CDC testing statistics are published here for Saipan County, Northern Mariana Islands yet. Radon411 has no EPA zone on file for Saipan County, Northern Mariana Islands. Homes with elevated levels occur in all three zones, so the figures describe the area, not your house. Testing is the only way to know the radon level in a specific building.
How do I get a radon test in Saipan County?
EPA says you can test your home yourself or hire a qualified radon test company, and that either approach takes only a small amount of time and effort. No certified tester listed on Radon411 names Saipan County as a service area yet. Your state radon program is the place to ask about certified testers and any test kit offer.

How radon mitigation worksWhat mitigation costsNorthern Mariana Islands radon program
What EPA radon zone is Saipan County in?
Radon411 has no EPA Map of Radon Zones classification on file for Saipan County, Northern Mariana Islands, so we are not going to state one. EPA's recommendation does not depend on the zone in any case: test every home.
Should I test my home in Saipan County?
Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
When is the best time of year to test?
EPA says short-term tests stay in the home from 2 to 90 days and that all radon tests should run a minimum of 48 hours; long-term tests stay more than 90 days. EPA's guides do not name a best season: they say radon levels tend to vary from day to day and season to season, so a long-term test is more likely than a short-term test to tell you the year-round average.
What does it cost to test?
EPA's Citizen's Guide calls testing easy and inexpensive, and EPA's Home Buyer's and Seller's Guide says passive short-term and long-term devices are generally inexpensive, while active devices may cost more. No national average price is published for this, so Radon411 does not give one. What testing costs.
Which counties border Saipan County?
