Determination of the boron content in polyethylene samples using the reactor Orphee
F. Gunsing, A. Menelle,, O. Aberle
The boron content of two unknown types of polyethylene has been determined relative to a known reference type. Samples of polyethylene, including a known boron-less one, were irradiated with thermal neutrons at the reactor Orph´ee at Saclay in France. Prompt gamma rays were measured with a CeBr3 detector and the intensity of the 478 keV line from the 10B(n,a1g)7Li* reaction was extracted for each sample.
