Current MAP requirements allow a 25% ground floor sampling variance from the ANSI-AARST testing protocol. However, if any of the units come back at or above 4 pCi/L, 100% ground floor testing is required. You can find the current radon policy in Chapter 9.5.C of the MAP guide: https://www.hud.gov/sites/documents/4430GHSGG-BM.PDF
Attached is a 2018 radon update from Pat Burke that supplements the existing policy: Radon Technical Updates Pat Burke November 2018
Multifamily has proposed eliminating the 25% sampling variance and requiring 100% ground floor testing. If approved, this change would go into effect when the new MAP guide is published. The guide is still going through review. (from a memo dated Aug 5th, 2020)
The new requirement has now largely passed and is in effect as of this writing (January 1st, 2022) and because of the ongoing pandemic, ScanTech is no longer performing surveys for OCCUPIED multi-family dwellings or nursing facilities. We only perform commercial surveys in unoccupied structures which are typically new builds, though we can still do office buildings under certain conditions such as in conjunction with other forms of indoor air quality testing.

In a rush to test your property for radon gas or radioactivity in natural stone such as granite or marble? Did you know that radon is the 2nd leading cause of lung cancer? (Smoking is 1st and radon gas synergistically increases mortality rates for smokers)
While it is not well known, radon gas levels EXCEED EPA action limits of 4 picoCuries/liter (pCi/L) in up to 10 % of all homes in Dallas county with an additional 14 % falling into the marginal range of 2 – 4 pCi/L. This means that 1 out of 4 homes (10 % + 14 % = 24%) in Dallas either have a radon issue or fall into a caution category. Other counties, such as Tarrant, Collin and Denton are not immune either. (see the link below on Radon FAQ from ScanTech for more details)
Example areas of the Metroplex (not a complete or comprehensive list) which have been found by ScanTech testing to have excess radon levels which are statistically higher than the 24 % quoted above include:
- North Dallas and Far North Dallas
- Lake Highlands
- University Park
- Highland Park
- Park Cities area
