Abstract
A simple and robust method for determination of 222Rn in natural waters is described. A 1.3-L water sample is collected in a plastic (PET) water bottle and shaken with 20 mL mineral oil scintillant for 4 minutes. Radon preferentially migrates to the mineral oil, and the 222Rn activity is determined by counting 222Rn and the short-lived daughter products 214Po and 218Po using an ultra-low-level LS counter via α/β separation technique. The PET method achieves a detection limit of ~3 mBq L-1, making it an ideal method for analysis of surface water and groundwater samples.
