If the question is correctly interpreted, then conversion from SSNTD's measurement of radon in water necessitates a Calibration Factor, either by experimental methods or by Monte Carlo Techniques. The same applies for measurement of atmospheric radon with SSNTDs. If an estimation of the contribution from radon in water to radon in air is needed, then a release factor from aqueous phase is also needed.
You can find such information in the following publications of me and my colleague Dr. Louizi:
1.NIKOLOPOULOS D, LOUIZI A, Study of indoor radon and radon in drinking water in Greece and Cyprus: Implications to exposure and dose, Radiat. Meas. 2008 43(7): 1305-1314.
Extensive modelling and analysis of the contribution of radon in water to radon in atmosphere may be found in the following publications:

For measuring correctly you need a good calibration before you conduct the measurements. You must be careful about the leakage of gas from the can or container in which you measure the concentration.
It is also depends on the procedure of sample collection.
There is a ratio between indoor radon and Radon releasing from water depending on the radium content in the water.
