Pb-210 and Cs-137 Dating
The CEN radiochronology laboratory offers Pb-210 and Cs-137 dating services for sediments using the HPGe (High-Purity Germanium detector) method.
It is also possible to count the isotopes Am-241, Cd-109, Co-57 as well as Ra-226 (which is the average of Pb-214 and Bi-214).
The laboratory has 2 detectors in operation, reducing waiting times for sample counting.
Sample Preparation and Submission
The sample preparation procedure is as follows:
- Contact us for the plastic vials required for counting.
- Dry your samples.
- Weigh your samples to an accuracy of 0.1 mg.
- Compact the sample as much as possible in the vial. Also, if possible, try to have a fairly similar volume (height) in each of the vials.
We also offer encapsulation (preparation) of your samples if you don't want to do it yourself. Before sending them to us, please make sure they are dry and well identified, in plastic vials or Ziploc bags.
