Pb 210 dating
We provide services for both short-term and long-term detection of radon gas.Short-Term Radon Detection Short-Term detection of radon gas is an average of the levels of radon gas over the past seven days.crystalline lattice), it is the ingrowth of lead-210 activity relative to radium-226 activity that provides a measure of time.In an ideal system there would be no exogenous source of lead-210 and the lead-radium ratio would increase purely from ingrowth.
Once radium-226 is incorporated and isolated by some kind of structure (e.g.
Lead dating - Pb-210 is an isotope in the uranium-238 (U-238) decay series. Although it can occur in secular equilibrium with its grandparent, Pb-210 concentrations are not constant because geo-chemical processes separate Pb-210 from the longer lived parent isotopes in many systems.
This separation and subsequent decay provides the opportunity for the use of Pb-210 as a dating tool.
In conjunction with the Geosciences Advisory Unit at the National Oceanography Centre in Southampton we are able to offer this relatively new technique for precisely dating very recent sediments.
This is particularly applicable in dating sediment accumulation rates for geohazard analysis in subsea engineering projects.
