Abstract
The present invention provides a method for determining a background count rate in liquid scintillation counting. The method comprises measuring external standard spectra of a sample, determining, from the external standard spectra, a triple to double coincidence ratio and a quench parameter, determining, based on the triple to double coincidence ratio and the quench parameter, a background reference parameter, and determining, based on the background reference parameter, the background count rate from a background reference curve.
Claims10
A method for determining a background count rate in liquid scintillation counting, wherein the method comprises:
- measuring external standard spectra of a sample using an external gamma radiation source;
- determining, from the external standard spectra, a triple to double coincidence ratio and a quench parameter;
- determining, based on the triple to double coincidence ratio and the quench parameter, a background reference parameter;
- and
- determining, based on the background reference parameter, the background count rate from a background reference curve.
