I have kept records of all the tests I have done since the middle of 2004.
I have done 162 tests. 41 have come back with high readings.
This is over 25% or 1/4. I believe the national average is 1/16
My highest reading is 27.7
I have tested in 57 different areas.
** Would this be acceptable to say to a client?** I have tested 10 homes in the city of _______ that you are planning on living in. 4 of the homes have tested over the recommended action guideline. The national average is one of 16 homes. Would you like to schedule a radon test today?
