ActLabs 4F-B : B by PGNAA

ActLabs Code 4F-B: whole rock analysis (WRA) code 4F add-on package for boron (2ppm) by PGNAA

General Methodology:

Samples 1 g in size are encapsulated in a polyethylene vial and placed in a thermalized beam of neutrons produced from a nuclear reactor. Samples are measured for the doppler broadened prompt gamma ray at 478 KeV using a high purity GE detector. Samples are compared to certified reference materials used to calibrate the system. A minimum of four standards are analyzed with every work order. Duplicates are analyzed when samples are provided. The detection limit reported is a function of the counting times required for each.
