The programme consists of a modular system of capsules which are used for Neutron Activation Analysis. The capsules are manufactured from very pure HDPE material. The production takes place with Posthumus Plastics using injection moulding in a clean room environment.
Neutron Activation Analysis (NAA) is an analysis technique capable of determining many elements at the same time at very low levels Neutron Activation Analysis is a method of qualitative and quantitative element analysis, in which the sample material is irradiated with neutrons in a nuclear reactor. In this process, stable isotopes are converted into radioactive isotopes. While these isotopes decay, having half lives varying from seconds to years, they are emitting different kinds of electromagnetic radiation, among which gamma radiation. This gamma radiation is measured with semi-conductor gamma-ray spectrometers. Each radionuclide emits gamma radiation of a certain wavelength or energy. So when you have a peak in your gamma-spectrum at a certain energy, you can determine with which element it corresponds. The peak area gives information about the amount of this element present in the sample.
