After that it has to be done with a gas-tight syringe, if example is taken with a syringe. The really initial and also probably the most important manipulation when a representative example requires to be taken is sampling at the place of the water resource. During this procedure a substantial fraction of radon can be shed. Besides sampling, storage space is another essential phase in radon evaluation.
