Radioactivity Measurements Laboratory
Using Pb-210

Offer

In 1997, a complete system for determination of 210Pb concentration in sediments was built and tested in the Department of Radioisotopes, Institute of Physics, GADAM Centre

Today we offer

Sampling
  • Lake sediment cores
  • Peat
  • Soil
Dating of samples by the 210Pb method (samples not older 200 years)
Deposition/Sedimentation rate calculations
The minimal mass required for measurement is ca 1-2 g dry mass of material. We can measure of 210Pb activity independently by alpha and gamma ray spectrometry methods.
Studies of human impact on water basins
One of the methods to determine human impact on water basins and ponds is monitoring of the sedimentation rate changes. Radioactive isotopes of lead, naturally present in the environment may be used for this purpose.
Changes of chemical composition of water in water basins and ponds may be caused by acid rains, farmland fertilisation, uncontrolled release of sewage. Deforestration as well as industrial activity in the vicinity of the water basin lead to changes in sediment composition.
The human impact on water basins is manifested at first as an eutrophysation of the basin, which then leads to changes in chemical composition of sediments and sedimentation rate.

The cost of one date is currently 300 PLN+VAT (23%) (cast in Euro depens on current exchange rate).

The price may be negotiated in case of large series of samples (over 10). We are also open to suggestions of scientific collaboration as well as applications for funding for joint projects.
