Radiometric dating detector

The time that it takes for half of a sample to decay is known as the half life of the isotope.

This approach can also be used in a number of other ways to investigate the distribution of radioisotopes in the environment through measurements of a wide range of environmental and ecological samples.

UK Environmental Change Research Centre, University College London ( Before sending samples for analysis it is important to contact either Handong Yang or Neil Rose (see Contacts) regarding up-to-date costs and the time from receipt of samples to reporting as this can vary depending on demand.

One problem is that potassium is also highly mobile and may move into older rocks.

This depends on the decay of uranium-237 and uranium-238 to isotopes of lead.

The UCL Environmental Radiometric Facility is located within the Department of Geography, University College London and uses low-background hyper-pure germanium gamma spectrometers capable of measuring low-level environmental radioactivity. This enables chronologies of 100 - 150 years to be accurately determined.The facility has undertaken these analyses for research projects based in many areas of the world.Some isotopes have half lives longer than the present age of the universe, but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
