RATE Research Goals
- Test the assumptions of radioisotope dating.
- Developing alternate models for interpreting radioisotope
- Write technical reports.
Current RATE Projects
- Theoretical models of accelerated alpha & beta decay.
- Search for dating concordance & discordance.
- Search for decay traces of short-half-life isotopes in rocks.
- Measurement of helium diffusion in minerals.
- Measurement of helium and argon content of minerals.
- Measure carbon-14 in coals.
- Very high abundances of radioisotope decay products occur in
- Different dating methods often give discordant dates for the
same rock or mineral.
- Radiogenic gases (argon and helium) occur in higher quantities
in minerals than conventional dating methods assume.
- Helium diffuses rapidly from minerals.
- Halos of short half-life elements occur in many common rocks.
