Additional Information |
All radiochemical drinking water samples are analyzed for gross alpha (4002), gross beta (4100), radium 228 (4030) and uranium mass. If the combined gross alpha and radium 228 radioactivity exceeds 5 pCi/L, then radium 226 is also analyzed. If gross beta radioactivity exceeds 50 pCi/L, then the Beta radiochemicals group is scheduled for collection and analysis. |
