Gamma counter for the measurement of 210Pb
The laboratory measures the natural gamma radiation in samples from sediment cores for 210Pb and its daughter products and 137Cs. Models are used to determine the sediment rate.
The facility has the capability of measuring 8-10 sediment cores per year with most of the samples (90%) coming from investigators at LU and a small portion of external samples measured. The process is slow and usually takes 2 months once dried sediment material is received from the user. Samples must be changed daily by a person. The prize is dependent on analytical time and amount of samples. Please contact laboratory manager for individual prize.
