Radon questions...

Dwelling built 2000
Active radon mitigation system functioning.

I did a radon test using my sunuclear 1027 in the finished walkout basement (2500 sq ft) 50 hours. Results came back at 5pci.

Clients are concerned.
I’m thinking on recommending and performing another short term test to confirm the results.

Should I charge my normal fee of $135?

What is the square foot area the sunuclear 1027 is adequate to test?

Thanks

I know with Air Chek 2500 sq ft is or on the verge of needing 4 kits set up in two separate areas.

Call sun nuclear for that info.

A long term test would be recommended.
Retests are charged to Client…
All subsequent results are averaged with original result.
You can use 2 monitors (if available)
Factor depends upon State requirement for square footage of testing…
Your state may vary from mine…

Remember…
the difference between 3.0 and 5.0 pCi/liter…
is 2 parts per Trillion…
