How soon does the sample need to get to the lab before it is invalid?
If you are using a Liquid Scintillation vial (48-96 hour) test it must be received in the lab within 8 days after the samples closing date.
If you are using a Charcoal Canister it must be received in the lab within 8 days after the samples closing date.
If you are using a Radon in Water test kit it must be received in the lab within 8 days after the samples closing date.
However, if you are taking a Radon water sample in the State of Connecticut it must be received in the lab within 4 days after the samples closing date.

After 30 days the result will be accompanied by the disclaimer "Delay between end of testing period & return to the lab may increase reported radon concentration. Consider retesting." After 60 days the result will be invalid and the comment will be "Unable to report a result due to excessive delay in receipt of test device."
