The Big Bottle System is an accessory for the RAD7 that enables users to measure radon in 2.5L water samples with high sensitivity. The lower limit of detection is well below 1 pCi/L (40 Bq/m3) radon concentration in water. The upper operating limit is 10,000 pCi/L (400,000 Bq/m3). For ranges higher than that, the standard RAD H2O accessory is ...
