Measurement Of Gross Alpha And Beta Radioacivity In Ground Water From Some Bore Holes And Wells In Kaduna North Local Government Area Of Kaduna State.

Gross beta determination in drinking water using scintillating fiber array detector

“…The measurement technology of gross alpha and beta in drinking water includes the evaporation concentration method, the co-precipitation method, and real-time monitoring. The evaporation concentration method usually takes a 0.1-2.0 L sample as total dissolved solid, and the sample is evaporated slowly to complete dryness, then the gross alpha and beta radioactivity levels can be calculated by measuring those of the solid residues [6.7] , and the detector can be a proportional counter [8,9] or scintillator detector [10,11] . This method has the advantages of the reliable measurement results and lower detection limit, but the sampling period is long and the sample process is complex, making it rather inefficient, especially in the case of an alert for unexpected radioactive events [12,13] , and this method does not allow for the determination of volatile radionuclides, making the results underestimated.…”
