Brief Method Summary
|
This method has been used to collect uranium and radium from fresh water samples at environmental levels. The use of the ion exchange collector concentrates the uranium and radium in the water samples and permits shipment of the samples within national and international regulations. Water samples collected with this system have been sent to EML from locations within the continental U.S., the middle East, and Africa. Similar collection methods for radium are in use elsewhere, notably at the New York University Institute of Environmental Medicine. |
|
Scope and Application
|
This procedure is a simple method for the field collection of uranium and radium in 10 L of fresh water (tap, well, river). |
|
Applicable Concentration Range
|
|
|
Interferences
|
(A) Filter paper pulp must not be used, as the flow rate through the column is too slow. Narrow strips cut from filter discs are recommended. |
|
Quality Control Requirements
|
Environmental sampling quality assurance measures are outlined in EML HASL-300 Procedures Manual (1997) - Quality Assurance. |
|
Sample Handling
|
Resin sampled may be analyzed sequentially for isotopic uranium and radium (see EML HASL-300 Procedure Se-01). |
|
Maximum Holding Time
|
None given. |
|
Relative Cost
|
Less than $50 |
|
Sample Preparation Methods
|
None given. |
