Extension of the calibration curve for the PGRA facility in Petten

S Nievaart et al. Appl Radiat Isot. 2009 Jul.

Abstract

At the boron neutron capture therapy (BNCT) facility in Petten, the Netherlands, (10)B concentrations in biological materials are measured with the prompt gamma ray analyses facility that is calibrated using certified (10)B solutions ranging from 0 to 210 ppm. For this study, newly certified (10)B solutions ranging up to 1972 ppm are added. MCNP simulations of the setup range to 5000 ppm. A second order polynomial (as already used) will fit (10)B-concentrations less than 300 ppm. Above 300 ppm a fitted third order polynomial is needed to describe the calibration curve accurately.
