Scientists want measurements that are both accurate and precise…but it can be difficult to tell sometimes whether very precise measurements are actually accurate without an independent reference age (see top right image versus bottom right image).

But it is important not to take these ages at face value, and to think critically about whether or not they may be accurate.Be) atoms in a boulder yield measurements of an exposure age with very low uncertainties. This analytical uncertainty does not take into account geological uncertainties – has your boulder rolled over, or has it been reworked and does it contain Be from a previous exposure?These factors may result in you having an exposure age that is both precise and inaccurate.Measuring the environmental dose rate for an OSL sample from Glen Tulla, Scotland.The gamma spectrometer has been put into the sample hole (see the lead going from the gamma spectrometer crystal to the control box).

Geological data frequently has difficulties in dating things, even if the analytical techniques can give very precise answers.
